Question 60

Which drug form is most rapidly absorbed from the gastrointestinal (GI) tract? a. Capsule b. Sublingual c. Liquid d. Tablet

Answer 60

c. Since liquid drugs do not need to dissolute and dissolve like tablets and capsules, they are absorbed more rapidly. Absorption of drugs is the movement of the drug from the gastrointestinal (GI) tract into the bloodstream after administration. Sublingual drugs enter the blood stream without having to be absorbed by the GI tract.

Question 61

Disintegration of enteric-coated tablets occurs in the:

a. colon. b. liver. c. small intestine. d. stomach.

Answer 61

c. Disintegration of enteric-coated (EC) tablets occur in an alkaline environment of the small intestine. Drugs that are EC resist disintegration in the stomach by the gastric acid.

Question 62

Usually food _______________________ dissolution and absorption of drug. a. increases b. decreases c. has no effect on d. prevents

Answer 62

b. Food usually decrease dissolution and absorption of drugs. However, there are some drugs that are irritating to the gastric mucosa. Food can decrease the irritating effects.

Question 63

Which statement places the four processes of pharmacokinetics in the correct sequence? a. Absorption, metabolism, distribution, excretion

b. Distribution, absorption, metabolism, excretion
c. Distribution, metabolism, absorption, excretion
d. Absorption, distribution, metabolism, excretion

Answer 63

d. Absorption, distribution, metabolism, and excretion are the correct sequence of pharmacokinetic phase. The drug must be absorbed from the GI tract into the bloodstream; drug must be distributed to the tissues; drug must be metabolized into an excretable form; the drug must be excreted.

Question 64

Which type of drug passes rapidly through the gastrointestinal (GI) membrane? a. Lipid-soluble and ionized b. Lipid-soluble and nonionized c. Water-soluble and ionized d. Water-soluble and nonionized

Answer 64

b. Drugs that are lipid-soluble and nonionized can readily pass through the GI membrane. The mucous membrane lining the GI tract is composed of lipids and protein which allows lipid-soluble drugs to pass through. On the other hand, water-soluble drug needs a carrier.

Question 65

Which factor(s) most commonly affect(s) a drug’s absorption? (Select all that apply.) a. Body mass index b. Hypotension c. Pain d. Sleep e. Stress

Answer 65

b, c, e. The gastrointestinal tract is not considered vital to a patient in shock and hypotensive, so blood is shunted away, and drug absorption is slowed. Blood flow is also slowed because of pain and stress, resulting in a prolonged emptying time of the stomach.

Question 66

Two days after starting diazepam for anxiety, the client is started on ampicillin with sulbactam for an infection. Which action will happen to the diazepam in the client’s body? a. The diazepam remains highly protein bound. b. The diazepam is deactivated. c. Most of the diazepam is released, and it be-comes more active.
d. The diazepam is excreted in the urine un-changed.

Answer 66

c. Both drugs are highly protein-bound. When two or more highly protein-bound drugs are taken at the same time, they compete for the protein-binding sites. The more highly bound drug could displace the weakly bound drug; ampicillin/sulbactam could displace diazepam, which results in increase activity of diazepam.

Question 67

Which body organ is the major site of drug metabolism? a. Kidney b. Liver c. Lung d. Skin

Answer 67

b. The liver is the major site of drug metabolism. Kidneys excrete the drug.

Question 68

Which route of drug absorption has the greatest bioavailability? a. Intramuscular b. Intravenous c. Oral d. Subcutaneous

Answer 68

b. The percentage of drug (bioavailability) for therapeutic activity is greatest after intravenous administration. Factors that affect bioavailability of drugs include drug form, route of administration, gastric mucosa and motility, food or other drugs, and liver function.

Question 69

Which is the best description of a drug’s serum half-life? a. The time required for half of a drug dose to be absorbed

b. The time required after absorption for half of the drug to be eliminated
c. The time required for a drug to be totally effective
d. The time required for half of the drug dose to be completely distributed

Answer 69

b. The best description is the time required for half of the drug to be eliminated. Other factors affecting drug’s half-life are amount administered, amount of drug remaining from previous dose, and metabolism.

Question 70

A client is taking a drug that has a half-life of 24 to 30 hours. In preparing discharge teaching, which dosing schedule would the nurse anticipate will be prescribed for this drug? a. Daily b. Every other day c. Twice per day d. Three times per day

Answer 70

a. A drug that has a half-life of 24 to 30 hours will be taken once daily to maintain a steady state.

Question 71

Which type of drug metabolite can be eliminated through the kidneys? a. Enteric-coated b. Lipid-soluble c. Protein-bound d. Water-soluble

Answer 71

d. Kidneys excrete drugs that are water-soluble, drugs that are not bound, and drugs that are un-changed.

Question 72

An older adult client with a glomerular filtration rate (GFR) of less than 30 has been prescribed trimethoprim for a urinary tract infection. If the nor-mal dose is 200 mg per day, which dosing would the nurse anticipate will occur with this client’s dosing regimen? a. The dose will double. b. The dose will decrease by one-half. c. The dose will stay the same. d. The dose will increase to three times per day

Answer 72

b. A decreased eGFR indicates renal dysfunction. Decreased eGFR is expected in older adults be-cause of their decreased muscle mass. Many drugs, including trimethoprim, are eliminated through the kidneys. To prevent toxicity, the dose would need to be decreased.

Question 73

Which statement provides the best determinant of the biologic activity of a drug? a. The fit of the drug at the receptor site b. The misfit of the drug at the receptor site c. The inability of the drug to bind to a specific receptor
d. The ability of the drug to be rapidly excreted

Answer 73

a. Drug is more active if it is able to “fit” at the receptor site. The drug-receptor interactions are similar to the fit of the right key in a lock.

Question 74

Which type of drug prevents or inhibits a cellular response? a. Agonist b. Antagonist c. Cholinergic d. Nonspecific drug

Answer 74

b. An antagonist prevents (inhibits) and/or blocks a response. An agonist activates receptors and/or produces a desired response. A cholinergic is a type of a receptor. Nonspecific drug can either be an antagonist or agonist; depends on the type of receptors the drug affects.

Question 75

A drug effect on receptors located in different parts of the body may initiate a variety of responses de-pending on the anatomic site. Which type of drug responds in this manner? a. Ligand-gated b. Nonselective c. Nonspecific d. Placebo

Answer 75

c. A nonspecific drug affects same type of receptors located throughout the body, producing both antagonist and agonist effects. On the other hand, a nonselective drug affects more than one type of receptors.

Question 76

Which term measures the margin of safety of a drug. a. Therapeutic range b. Therapeutic index c. Duration of action d. Biologic half-life

Answer 76

b. Therapeutic index describes the relationship between the therapeutic dose and the toxic dose.

Question 77

Which measurement checks for the highest plasma/ serum concentration of the drug? a. Peak level b. Minimal effective concentration c. Half-life d. Trough level

Answer 77

a. Measurements that check a drug’s concentration include peak and trough levels; peak level measures the highest serum concentration and the trough level measures the lowest serum concentration of the drug.

Question 78

Which data would be important for the nurse to check in a drug reference book or pamphlet before administering a drug?(Select all that apply.) a. Contraindications b. Half-life c. Maximum effective concentration d. Protein-binding effect e. Therapeutic range

Answer 78

a, b, d, e. The nurse must be completely familiar with any drug being administered, such as contraindications, half-life, protein-binding effect, and therapeutic range. Information needs to be obtained not only on the drug but also on the specific patient’s history. Drug reference books, drug pamphlets/inserts, or a pharmacist may be consulted with questions.

Question 79

Which types of physiologic effects are predictable or associated with the use of a specific drug? a. Severe adverse reactions b. Side effects c. Synergistic effects d. Toxic effects

Answer 79

b. Side effects are secondary effects of all drugs and are often predictable. They may be desirable or undesirable. Adverse reactions, either mild or severe, are unintentional, unexpected reactions that occur at normal dosages. Synergistic effects occur when two or more drugs given together have a combined effect greater than the sum of their separate effects. Toxic effects are undesirable drug effects, often times life-threatening.

Question 80

Which term is illustrated when the nurse gives a large initial dose of a drug to rapidly achieve mini-mum effective concentration in the plasma? a. Therapeutic dose b. Toxic dose c. Loading dose d. Peak dose

Answer 80

c. Loading dose is a larger than usual dose to obtain a therapeutic effect while waiting for the steady state to be achieved.

Answer 81

a, b, c. A time-response curve shows the dose-relationship of the drug’s pharmacodynamics, which include onset, peak, and the duration of the drug’s action.

Question 82

Which intervention(s) regarding drug therapy would the nurse implement? (Select all that apply.) a. Assess for side effects, with a focus on undesirable side effects.

b. Check reference books or drug inserts before administering the medication.
c. Teach the patient to wait 1 week after the appearance of side effects to see if they disappear.
d. Check the patient’s serum therapeutic range of drugs that have a narrow therapeutic range.
e. Evaluate peak and trough levels before administering drugs with a narrow therapeutic range.

Answer 82

a, b, d, e. The nurse should assess the client for side effects (both desirable and undesirable) when administering drugs. This is especially important for drugs that have nonselective actions. The nurse must be familiar with the drug, including its dose range, desired effects, side effects, and ad-verse effects, before administration. This information can be obtained from a variety of sources including current reference books, drug inserts, and pharmacists. If the drug has a narrow therapeutic range or requires peak/trough levels, these should be evaluated before and after administration. Side effects may occur immediately or up to several days after a dose. There is no set time to wait and see if side effects disappear. The health care provider should be notified as soon as possible after the appearance of side effects, especially if they are undesirable.

The nurse noticed a client has been taking ginseng. Which interventions would be appropriate by the nurse? (Select all that apply.) a. Discuss with the client the potential interactions of ginseng with anticoagulants.

b. Tell the patient to stop taking the anticoagulant.
c. Advise the client to continue taking the same brand of herbal therapy.
d. Advise the client to report signs and symptoms of bleeding.
e. Discuss with the client foods to avoid.

Answer 96

a, d, e. The nurse should intervene by discussing with the patient that ginseng can interfere with the anticoagulants and increase the chance of bleeding; therefore, the patient should report any signs or symptoms of bleeding, such as bleeding of gums, black and tarry stools, and blood in the urine. Although educating the patient about the potential food-drug interactions while taking an anticoagulant, it is not appropriate in this specific scenario

Question 97

Which statement(s) by the client reflect(s) prudent use of herbs? (Select all that apply.) a. “Herbs are fine to use when breastfeeding.” b. “Do not take a large quantity of any one herbal product.”

c. “Give the herb time to work for a persistent symptom before seeking care from a health care provider.”
d. “Do not give herbs to infants or young children.”
e. “Brands of herbal products are interchange-able.”

Answer 97

b, d. Large quantities of any one herbal product can lead to an “overdosage” of that product. Because specific doses and quantities are not regulated in this country, it is difficult to determine the correct amount. More is not necessarily better. Infants and children should not receive herbal preparations because of the lack of standardization and testing in a pediatric population.

Question 98

The nurse is caring for a client who takes a variety of herbal products and is starting a prescription antidiabetic drug. The nurse teaches the client knowing that the effects of an antidiabetic drug are altered with which herbal products? (Select all that apply.) a. Astragalus b. Echinacea c. Ginseng d. Milk thistle e. Peppermint

Answer 98

c, d. Ginseng and milk thistle can have an additive effect when used with antidiabetic drugs causing hypoglycemia.

Question 99

Which drug(s) has/have negative interactions with St. John’s wort? (Select all that apply.) a. Anticoagulants b. Anticonvulsants c. Antidepressants d. Birth control drugs e. Paralytic drugs

Answer 99

a, b, c, d. St. John’s wort interacts with multiple drugs including anticoagulants and antiplatelets, anticonvulsants, antidepressants, and drugs for birth control. St. John’s wort can increase bleeding time; it can cause decreased drug levels of anticonvulsants and oral contraceptives; it can increase serotonin levels, leading to serotonin syndrome.

Question 100

A client with a history of hypertension, atrial fibrillation, chronic obstructive pulmonary disease, and insomnia tells the nurse, “I really love the taste of licorice.” What drug-herb interactions should the nurse inform the client can occur when given in combination with licorice? (Select all that apply.) a. Antihypertensive drug effects are decreased. b. Corticosteroid effects are increased. c. CNS depressant drug effects are decreased. d. Digoxin effects are increased. e. Rifampin effects are decreased.

Answer 100

a, b, d. The effects of antihypertensive medications may be decreased. Because licorice may have similar effects to aldosterone and corticosteroids, the effects of corticosteroid drugs may be in-creased. Taking licorice with digitalis may increase the effects of digitalis and lead to digitalis toxicity.

Question 108

The nurse is administering an oral drug with a low pH to a 2-week-old infant. Which action describes the impact of the infant’s age on the absorption of this drug? (Select all that apply.) a. Absorption may be slower in this infant. b. Absorption may be quicker in this infant. c. This drug will be absorbed at the same rate as an older client.
d. Oral drugs should not be administered to this age group.

Answer 108

a, b. Absorption depends on the drug formulation (basic [alkalotic] or acidic). A low pH environment favors acidic drug absorption, whereas a high pH favors basic drug formulations.

Question 109

The 18-month-old child has been prescribed an oral drug that is water-soluble. Based on the nurse’s knowledge of drug distribution, how may the dosage need to be modified for the child to reach therapeutic level? a. Alternate route b. Decreased c. Increased d. No change

Answer 109

c. The dosage for a water-soluble medication may need to be increased in this age group because their bodies are about 70% water up until age 2 years. Therefore, there is more water in which the drug will be distributed

Question 110

Since the blood-brain barrier in infants is immature, which drug outcome is more likely? a. Increased effect of drug b. More side effects from drug c. Quicker results of drug d. Higher toxicity risk

Answer 110

d. Immature blood-brain barrier allows drugs to pass easily into the central nervous system tissue (brain), increasing the risk of toxicity. As a child matures, the blood-brain barrier becomes more impervious to drugs.

Question 111

Which drug action does the nurse know about the rate of absorption for topical drugs to a 3-year-old child? a. The drug will absorb faster. b. The drug will absorb slower. c. There will be no difference. d. It depends on the sex of the child.

Answer 111

a. The drug will absorb faster. One of the factors in which the degree and rate of drug absorption is age. The skin of infants and young children is thinner than that of adults. Furthermore, the ratio of body surface area to body mass is proportionately higher than for adults. Topical drugs are readily absorbed and toxicity can result. Sex of a child does not in-fluence drug absorption.

Question 112

Which components are related to pharmacokinetics? (Select all that apply.) a. Absorption b. Distribution c. Excretion d. Metabolism e. Onset

Answer 112

a, b, c, d. Pharmacokinetics include drug absorption, distribution, metabolism, and excretion.

Question 113

A child has been admitted for nausea, vomiting, and diarrhea, and the health care provider has pre-scribed several drugs. Which concern(s) are appropriate for the nurse to have regarding drug administration? (Select all that apply.) a. Renal tubular function is decreased. b. Dehydration may lead to toxicity. c. The drugs should not be administered by the oral route.

d. Rectal administration will promote quick ab-sorption.
e. Developmental levels must be considered.

Answer 113

a, b, c, e. In early adolescence, renal tubular function decreases, which may lead to impaired excretion and a higher risk for toxicity. Dehydration can also decrease renal function and may lead to toxicity. Because the client is nauseated and vomiting, drugs should not be administered orally. When providing care to any client, developmental levels should be considered.

Question 114

The nurse is teaching a group of parents how to administer drugs to their children. Which element(s) of drug administration will be included in the teaching? (Select all that apply.) a. Allow the child to determine the time of drug administration.

b. Lightly restrain the child as needed. c. Praise the child after successful administration. d. Never threaten the child into taking the drug. e. Never tell the child what to expect; just give the drug.
f. Herbal preparations should not, in general, be given to children.

Answer 114

b, c, d, f. If necessary, a child may be lightly restrained but should not be forcibly held down. The child should be praised for taking the drug. At no time should a child be threatened, forced, or made to view the medication as punishment. Depending on the developmental level of the child, explanations should be given to the child about what to expect, but the child should not be given the option of debating whether to take the drug. Herbal preparations are not usually given to children; however, cultural traditions should be respected as much as possible.

Answer 128

False. Risk factors associated with polypharmacy include over-the-counter (OTC) drugs, in addition to female gender, having multiple health care providers, use of herbal therapies, advanced age, multiple chronic disorders, and frequency of hospitalizations and care transitions.

Question 129

Beers criteria is a document that lists drugs that has negative interactions in older adults when they drink alcohol.

Answer 129

False. Beers criteria is a document developed by the American Geriatric Society listing drugs to avoid among older adults and information on renal dosing and drug-drug interactions.

Question 130

Answer 130

True

Question 131

Polypharmacy increases the risk of falls among older adults.

Answer 131

True

Question 132

Which lab result is an indicator of normal glomerular filtration rate for an adult? a. Creatinine clearance: 100–125 mL/min b. Aspartate aminotransferase: 4–12 mL/min c. Troponin: 80–120 mL/min d. Urea: 1.2–4.5

Answer 132

a. Creatinine clearance is determined by the glo-merular filtration rate (GFR). Normal working kid-neys will have a GFR of 100 to 125 mL/min. Aspar-tate aminotransferase (AST) measures the liver function. Troponin is a type of protein found in skeletal and heart muscles. Urea is a waste product.

Question 133

The safest antihypertensive drugs for older adults have a low incidence of which side effect? a. Constipation b. Electrolyte imbalance c. Loss of appetite d. Vision disturbances

Answer 133

b. Renal function is decreased in older adults, which can cause electrolyte imbalance. Also, decreased renal function can lead to prolonged half-life and elevated drug levels. Certain antihypertensives like ACE-I, potassium-sparing diuretics, and thiazide diuretics can worsen electrolyte imbalance.

Question 134

An older adult client recently started on diphen-hydramine for runny nose, headache, sneezing, and scratchy eyes. List of drugs taken on a daily basis in-cludes digoxin, fluoxetine, and a multivitamin on a daily basis. a. “I cannot work outside anymore because of the digoxin.”

b. “I think I need to find a different allergy drug to take.”
c. “I take fluoxetine because I have depression.” d. “I should not take my wife’s headache drug.”

Answer 134

a. There is no reason that the client cannot work outside while taking digoxin, and the client’s symptoms are not related to the digoxin. Diphenhydramine can be very sedating among older

Question 135

Which drug would have fewer adverse and toxic effects while maintaining its therapeutic effect? a. Half-life of 50 hours b. 90% protein bound c. Half-life of 4 hours d. Fat-soluble

Answer 135

c. Drugs with a shorter half-life will be eliminated from the body faster than drugs with longer half-life without interfering with its therapeutic effect. Quicker elimination will decrease the risk of ad-verse/toxic drug effects. More protein binding the drug has, the less active drug is available to exert its therapeutic effect. Fat-soluble drugs have greater volume of distribution and a prolonged period of action. This can also increase the risk for toxicity.

Question 136

Which lab value(s) will the nurse monitor in an older adult client to assess kidney function? (Select all that apply.) a. BUN b. Creatinine clearance c. CBC d. Lipase e. Triglycerides

Answer 136

a, b. BUN (blood urea nitrogen) and creatinine clearance are assessed to determine renal function.
The ability for the kidneys to excrete drugs de-crease with age. CBC (complete blood count) is a test that evaluates red blood cells, white blood cells, and platelets. Lipase is a pancreatic enzyme. Triglycerides are a type of fat.

Question 137

An older adult client reports feeling dizzy every morning when getting out of bed. Which physio-logical effect does the nurse recognize the client is most likely experiencing? a. Bradycardia b. Intermittent claudication c. Hyperventilation d. Orthostatic hypotension

Answer 137

d. Dizziness when going from a supine to a standing position is referred to as orthostatic hypotension. Although bradycardia may cause dizziness, this is not the most likely cause.

Question 138

Which actions would the nurse recommend to a client who experiences dizziness when arising from bed? a. Change positions slowly. b. Move a chair close to the bed. c. Take deep breaths. d. Measure pulse before standing.

Answer 138

a. Changing positions slowly should assist in de-creasing the dizziness associated with hypotension related to changes in position. Taking a deep breath and checking heart rate will not affect dizziness. Having a chair close to the bed may be beneficial if the client feels dizzy but may also pose a safety risk; the client may strike the chair with fainting.

Question 139

Following hospitalization, the older adult client re-ceives a home visit from the nurse. The client asks if
the drugs taken before hospitalization should continue. Which response would be appropriate by the nurse? a. “Yes, you should continue to take the drugs that you took before going to the hospital.”
b. “You should take one-half the dosage of each drug that you took prior to hospitalization.”
c. “You should take only the drugs that have been prescribed on discharge and not drugs that you took prior to hospitalization unless otherwise indicated.”
d. “You should continue to take those drugs that have been helpful to you.”

Answer 139

c. When a person has been hospitalized, a drug reconciliation has been completed. Depending on the client’s response, drugs may be added to or subtracted from the regimen and dose adjustments may be made. The client should take only those drugs that have been prescribed at discharge.

Question 140

The older adult client has difficulties opening the bottle of celecoxib. Which response is appropriate by the nurse? a. “Please ask your pharmacist to place your drug in a bottle with a non-childproof cap.”

b. “You can keep your drug in a glass cup in the medicine cabinet.”
c. “You could place your drug in an envelope.” d. “A family member could help you with your daily drug regimen.”

Answer 140

a. Although a family member could assist with the daily drug regimen, the client will be able to maintain more independence using a non-childproof cap. Us-ing a non-childproof cap should make the container easier for the older adult client to grasp and open.

Question 141

An older adult client is to take newly prescribed drugs at different times. Which suggestion by the nurse would be appropriate so that the client can adhere with the drug regimen? a. “Line up the bottles of medications on a table and take them in that order.”

b. “Obtain a weekly pill container with multiple time slots from the drugstore and fill the container the day or week before with the drugs.”
c. “Ask a neighbor to give the daily drugs.” d. “Write down the drugs that you have taken each day.”

Answer 141

b. Maintaining independence for as long as possible is crucial for an older adult client. A client who
has visual challenges can, with assistance, fill a drug-dispensing container for the upcoming week. The client must have assistance in the setup to assure that the correct drugs are in each separate compartment. Leaving the drug bottles on the counter could lead to a mix-up if they are dis-placed. Writing down which drugs need to be taken is not beneficial if the patient has visual challenges.

Question 142

In older adults, drug dosages are adjusted based on which factor(s)? (Select all that apply.) a. Amount of adipose tissue b. Height c. Nutritional status d. Laboratory results e. Response to drug

Answer 142

a, c, d, e. Of the listed factors, only height does not have a role in dosage adjustment. Older adults have more adipose tissue, so a greater amount of lipid-soluble drug would be absorbed. Protein is required for binding of some drugs, so if a patient is malnourished, there would be less protein avail-able, leading to more free drug; this can lead to drug toxicity. Laboratory results, specifically those that assess renal and hepatic function, are important to trend, as well as those drug levels (digoxin, INR) needed to measure toxicity. As with any population, it is important to evaluate the client for responsiveness to the drug.

Question 143

Before administering drugs to the older adult, which drug information(s) would the nurse know beforehand? (Select all that apply.) a. Whether the drug is highly protein bound b. Half-life of the drug c. Patient’s last bowel movement d. Serum levels of drugs with a narrow therapeutic range
e. Baseline vital signs

Answer 143

a, b, d, e. Older adults have less protein available for binding, so it is important to know if a drug is highly protein bound. Drugs with a short half-life are less likely to cause problems for the client. Certain drugs (some antibiotics, digoxin, warfarin) have very narrow therapeutic ranges, so they must be monitored closely. Vital signs may vary as a client ages; therefore, it is important to obtain baseline vital signs to know the client’s norm.

Question 159

A client is seen in the emergency department for reportedly swallowing a small balloon full of cocaine. Which clinical manifestations would the nurse expect to see if the balloon ruptured? a. Dilated pupils and restlessness b. Hypotension and tachycardia c. Insomnia and fine tremors d. Respiratory depression and pinpoint pupils

Answer 159

a. Cocaine can cause dilated pupils (not pinpoint pupils) and restlessness. It can also cause hypertension (not hypotension), tachycardia, insomnia, erratic behaviors (not fine tremors), and tachypnea (not respiratory depression).

Question 160

Which drug can be given to aid a client with opioid withdrawal? a. Disulfiram b. Lorazepam c. Methadone d. Naloxone

Answer 160

c. Methadone is a long-acting opioid that is effec-tive in treating persons addicted to opioids by blocking the sensation of euphoria and tranquility produced by opioids, and it prevents opioid with-drawal and craving. Dronabinol is a synthetic can-nabis, lorazepam is a benzodiazepine to decrease anxiety, and naloxone is a reversal agent for opi-oid-induced respiratory depression.

Question 161

The client has decided to quit smoking. Which key point(s) must the nurse include in the teaching plan? (Select all that apply.) a. Assess that the client is motivated to quit. b. Assist in setting a quit date of 1 month. c. Help the client identify what increases the de-sire to smoke.

d. Advise the client to use chewing tobacco as a substitute.
e. Provide the client with a list of smoking cessation aids.

Answer 161

a, c, e. A client must be ready and motivated to quit any addictive substance, or the likelihood of success is decreased. This is a difficult process that will re-quire the client’s commitment. Certain triggers, like places where a person smokes or times that trigger the craving for a cigarette, should be identified and alternatives determined. There are a variety of aids, both pharmacologic and nonpharmacologic, that can be utilized to help a client quit smoking. Ideally, a quit date of 1 to 2 weeks should be set so the client stays motivated. Tobacco in any form is still addictive, so chewing tobacco or smoking tobacco in a pipe instead of a cigarette is still abusing tobacco. Although it is difficult, some clients prefer to quit smoking “cold turkey” or without the use of aids.

Question 162

Which percentage of nurses abuse drugs and demonstrate impaired practice attributable to that abuse? a. 1–2% b. 3–6% c. 7–10% d. 10–15%

c. “Crush the drugs and throw them in the trash.” d. “Throw them in the trash after mixing the drugs with unpalatable nonfood substance.”

Answer 173

d. Unused drugs should not be disposed in a manner that is connected to the sewage. Instead, it is best to dispose of them by taking the drug to a facility that has a “take-back” program. If this is not available, then drugs should be mixed whole in an unpalatable nonfood substance, such as kitty litter or dirt prior to placing them in the regular trash. It should not be crushed prior to mixing it.

Question 207

A client with asthma asks the nurse how albuterol inhaler will work to help breathe better. Which response by the nurse best explains the action of the drug? a. “Albuterol will increase your heart rate so you will feel like you are able to breathe better.”

b. “Albuterol causes the airways to open up more in the lungs, improving function.”
c. “Albuterol will cause an increase in urinary output to remove extra fluid from the lungs.”
d. “Albuterol causes bronchial smooth muscle contraction that forces air into the lungs.”

Answer 207

a, c, d. Complications associated with TPN include air embolism, hyperglycemia, and pneumothorax. Air embolism can occur when air enters the central line catheter. TPN consists of hypertonic dextrose solution which can increase serum glucose. Pneumothorax is air or gas in the pleural space causing the lungs to collapse. This can occur due to punctured lung during the procedure in inserting the central line. Aspiration can occur with enteral tube feeding, not because of TPN.

Question 208

A client presents to the clinic with a swollen face and tongue, difficulty breathing, and audible wheezes after eating a peanut butter sandwich for lunch. Which action would the nurse first take? a. Ensure a patent airway. b. Obtain an electrocardiogram (ECG). c. Administer 1 mg of 1:1000 epinephrine subcutaneously.
d. Start an intravenous (IV) normal saline.

Answer 208

. Ensuring a patent airway is the first step in providing care to any client. There is no indication currently for an electrocardiogram. Although epinephrine is beneficial in allergic reactions, 1 mg of 1:1000 exceeds the subcutaneous dosage. Establishing an IV would not be the first action to take.

Question 209

A client calls the home health agency to tell the nurse about shaking and trembling after using the albuterol inhaler. Which question would the nurse first ask the client? a. “Are you having any other symptoms?” b. “How long ago did this start?” c. “When was the last time you used your inhaler?”
d. “How many puffs on the inhaler did you take?”

Answer 209

d. Although all pieces of information are important, the nurse should ask the client how many puffs of the inhaler were taken to determine that the client did not overdose on the drug. Other side effects of albuterol, besides shaking and trembling, include sweating, nausea, headaches, blurred vision, and flushing.

Question 210

Which drug(s) is/are classified as beta blockers? (Select all that apply.) a. Albuterol b. Atenolol c. Propranolol d. Amphetamine e. Acebutolol

Answer 210

Question 211

The nurse discovers an intravenous (IV) site has infiltrated on a client receiving intravenous (IV) dopamine. The nurse prepares to administer which drug as an antidote. a. dobutamine b. epinephrine c. phentolamine d. reserpine

Answer 211

c. Dopamine is a vasopressor (adrenergic agonist) that acts on alpha1-and beta1-receptor sites. Dopamine can cause tissue necrosis. Phentolamine mesylate is an adrenergic antagonist and is an antidote to stop further tissue necrosis. Dobutamine and epinephrine are also adrenergic agonists that can cause tissue necrosis. Although reserpine is an adrenergic neuron antagonist, it is used to treat hypertension.

Question 212

When completing the client health history, the nurse finds a history of narrow-angle glaucoma. When performing the drug reconciliation, which drug would concern the nurse? (Select all that apply.) a. Pseudoephedrine b. Midodrine c. Albuterol d. Carvedilol

Question 213

Some over-the-counter (OTC) drugs for cold symptoms contain substances that have sympathetic properties. These drugs are contraindicated in clients with which disease process? a. Allergic rhinitis b. Hypertension c. Orthostatic hypotension d. Chronic bronchitis

Answer 213

b. Many OTC drugs, such as nasal decongestion, contain pseudoephedrine, which is a sympathomimetic; they can worsen hypertension.

Question 214

Which adrenergic drug used in emergency settings does not decrease renal function? a. Norepinephrine b. Dopamine c. Phenylephrine d. Dobutamine

Answer 214

b. Dopamine acts primarily on dopaminergic receptors and are located in renal, mesenteric, coronary, and cerebral arteries. These dopaminergic receptors can only be activated by dopamine. When these receptors are stimulated, vasodilation and increased blood flow occur, which can increase renal flow.

Question 215

Beta1 receptors are located in which area of the body? (Select all that apply.) a. Gastrointestinal tract b. Lungs c. Kidneys d. Brain e. Heart

Answer 215

Bethanechol is a direct-acting cholinergic agonist and is used to treat urinary retention. Metoclopramide, a direct-acting cholinergic agonist, is used to treat gastrointestinal (GI) symptoms.

Question 222

The pediatric client has urinary retention. Which cholinergic drug does the nurse anticipate will be prescribed to increase urination? a. Bethanechol b. Edrophonium chloride c. Metoclopramide d. Neostigmine bromide

Answer 222

a. Bethanechol, a direct-acting cholinergic agonist, is used to treat urinary retention. Metoclopramide, a direct-acting cholinergic agonist, is used to treat gastrointestinal (GI) symptoms. Neostigmine bromide is used to treat myasthenia gravis.

Question 223

Anticholinergic eyedrops are used for which purpose? a. Constrict the pupils b. Dilate the pupils c. Decrease the intraocular pressure d. Detect astigmatism

Answer 223

b. Anticholinergics inhibit the acetylcholine receptors and include muscarinic and nicotinic receptors. Anticholinergic eyedrops causes dilated pupils (mydriasis). Cholinergic agonists will constrict pupils. Direct-acting cholinergic agonists will de-crease intraocular pressure.

Question 224

A client with narrow-angle glaucoma is prescribed an anticholinergic drug. Which action would be a priority by the nurse? a. Administer the medication as ordered after verifying the patient’s identity.

b. Give only one-half of the prescribed dose. c. Hold the dose and contact the health care provider.
d. Wait until after the patient has taken glaucoma medication and then give the drug.

Answer 224

c. Anticholinergic drugs are contraindicated in a client with glaucoma because they increase the intraocular pressure. Therefore, the nurse should hold the drug and contact the prescriber.

Question 225

Which statement describes the mechanism of action for Bethanechol? a. Inhibits muscarinic receptors b. Inhibits nicotinic receptors c. Stimulates muscarinic receptors d. Stimulates nicotinic receptors

Answer 226

c. Bethanechol, a direct-acting cholinergic agonist, works on the muscarinic receptor. Nicotinic receptors work on skeletal muscles. Anticholinergics inhibits muscarinic and nicotinic receptor.

Question 227

The client who was prescribed Bethanechol asks the nurse how it works. Which response would be most appropriate by the nurse? a. “This drug decreases bladder tone.” b. “This drug inhibits bladder contraction.” c. “This drug promotes contraction of the bladder.” d. “This drug stimulates urine production.

Answer 227

c. Bethanechol, a direct-acting cholinergic agonists stimulates the muscarinic receptors to contract bladder which increases urination.

Question 228

Which outcome to the body would occur from receiving large doses of cholinergic drugs? (Select all that apply.) a. Decreased blood pressure b. Decreased salivation c. Increased bronchial secretions d. Mydriasis e. Urinary retention

Answer 228

a, c. Cholinergic drugs are parasympathomimetic in that they mimic the parasympathetic responses. One response is the dilation of blood vessels, which decreases blood pressure. Other responses include pupillary constriction (miosis), bronchoconstriction and increased bronchial secretions, decreased heart rate, increased gastrointestinal peristalsis and secretions, bladder contraction, and increased salivation.

Question 229

The client has been prescribed Bethanechol and is experiencing decreased urinary output. Which action would be a priority by the nurse? a. Catheterize the client to drain the bladder and
measure output.
b. Encourage the client to increase fluid intake to increase urinary output.
c. Encourage the client to relax when urinating. d. Notify the health care provider with current in-take and output values.

Answer 229

d. Bethanechol is used to treat urinary retention but will not be effective and should not be used in the case of a mechanical obstruction. If this client was prescribed Bethanechol for urinary retention and the urine output is decreasing, the health care provider should be notified to investigate another cause

Question 230

The client has been taking Bethanechol and is experiencing flushing, sweating, nausea, and abdominal cramps. Which action would be best for the nurse to take? a. Document the client’s manifestations. b. Give the client a laxative. c. Increase the client’s fluid intake. d. Obtain an order to administer atropine.

Answer 230

d. Bethanechol is a cholinergic agonist. The client is experiencing an adverse response, and the treatment of choice is atropine. The nurse should obtain an order to administer atropine, the antidote for cholinergic overdose. The nurse should document the client’s experiences, but it is not the best action by the nurse. Abdominal cramps is due the action on the muscarinic receptors, not due to constipation. Increasing fluid intake will not relieve the side effects of Bethanechol.

Question 231

Which drug treats myasthenia gravis by increasing muscle strength? a. Bethanechol b. Edrophonium chloride c. Neostigmine bromide d. Pilocarpine

Answer 231

c. Neostigmine bromide is used to treat myasthenia gravis (MG). Bethanechol is used to treat urinary retention. Pilocarpine is used to treat glaucoma.

Question 232

The nurse is taking care of five clients in the emergency department. Which client(s) would be candidate(s) to receive atropine? (Select all that apply.) a. A client having surgery for appendicitis b. A client with a heart rate of 38 beats/minute and dizziness
c. A client with paralytic ileus d. A client with urinary retention e. A client with gastric ulcers

Answer 232

a, b. Atropine would be beneficial as a preoperative drug to help control oral secretions. It is also used for clients who are symptomatic with a heart rate less than 50 beats per minute and is symptomatic of decreased cardiac output. Bethanechol is for urinary retention. Benztropine is for paralytic ileus. Propantheline bromide is used for gastric ulcers.

Question 233

The nurse would question an order for atropine for which client? a. A client with a peptic ulcer b. A client with parkinsonism c. A client with cirrhosis d. A client with narrow-angle glaucoma

Answer 233

d. Atropine-like drugs should not be administered to clients with narrow-angle glaucoma because they will increase the intraocular pressure.

Question 234

The client with new diagnosis of peptic ulcers was prescribed propantheline. Which substance would the nurse teach that is a priority point for nutrition? a. Calcium b. Fat c. Fiber d. Protein

Answer 234

c. Because of the decrease in gastrointestinal motility that can be associated with propantheline, the client should be encouraged to eat foods that are high in fiber and drink adequate amounts of liquid to prevent constipation.

Question 235

Which teaching point(s) will the nurse include for a client taking hyoscyamine for irritable bowel syndrome? (Select all that apply.) a. Ensure adequate fluid intake. b. Do not drive until you are aware of how this drug will affect your vision.

c. Sucking on hard candy may help with dry mouth.
d. Increased sweating is a common side effect. e. Report a rapid heart rate to your health care provider.

Answer 235

a, b, c, e. Hyoscyamine is an anticholinergic drug that will have similar side effects to the prototype drug atropine. Adequate fluid intake will help pre-vent constipation. Vision may be blurry, and the client should be advised not to drive until the effects of the drug on the vision are known. Sucking on hard candy or sugar-free ice pops, as well as increased fluid intake, may help with dry mouth. The client should be educated as to baseline heart rate and advised to report tachycardia (rates above 100 beats/minute) to the health care provider. In-creased sweating is not a common side effect.

Question 236

Anticholinergic drugs are contraindicated in clients with which disease processes? (Select all that apply.) a. Coronary artery disease b. Diabetes mellitus c. Gastrointestinal obstruction d. Supraventricular tachycardia

Answer 236

a, c, d. Anticholinergic drugs block the normal parasympathetic responses of the pupils, lungs, heart, blood vessels, gastrointestinal tract, bladder, and salivary glands. Therefore, anticholinergic drugs are contraindicated in clients with any heart disease and diabetes mellitus.

Question 237

A specific group of anticholinergics may be pre-scribed in the early treatment of which neuromuscular disorder? a. Multiple sclerosis b. Muscular dystrophy c. Myasthenia gravis d. Parkinsonism

Answer 237

d. Anticholinergics, such as biperiden and benztropine, are used to treat early Parkinson. Anticholinesterase, not anticholinergics, are used to treat myasthenia gravis.

Question 238

The older adult client is taking benztropine for symptoms associated with parkinsonism. The nurse will instruct the client to report which clinical manifestation(s) to the health care provider? (Select all that apply.) a. Diarrhea b. Dizziness c. Hallucinations d. Hyperthermia e. Palpitations

Answer 238

b, c, d, e. Common side effects of anticholinergic drugs, like benztropine, may include dry mouth, constipation, and urinary retention. Dizziness and hallucinations should be reported to the health care provider because these may become dangerous to the client. Because there is a decreased ability to perspire,
life-threatening hyperthermia may develop. Palpitations may be due to tachycardia.

Question 250

The client has been prescribed phentermine hydrochloride for obesity. The client also has Parkinson disease and takes selegiline. Which nursing action would the nurse do before the client starts the new
drug? a. Contact the client’s primary health care provider to
verify the prescription.
b. Have baseline lab work drawn to assess liver function.
c. Tell the client to immediately stop taking the selegiline.
d. Tell the client to increase fluid intake with the next meal

Answer 250

a. Phentermine hydrochloride should not be taken within 14 days of monoamine oxidase inhibitors (MAOIs) such as selegiline. Combinations of the two drugs intensify the stimulation and vasopressor effects of phentermine that can cause severe cardiovascular and cerebrovascular responses. There-fore, the nurse should contact the health care provider to verify the prescription.

b. Anesthetic
c. Sedative-hypnotic
d. Triptan

Answer 275

c. Sedative-hypnotics are commonly prescribed to treat sleep disorders. Analeptics are CNS stimulants. Anesthetics are CNS depressants and are not prescribed for sleep. Triptans help with migraines.

Question 276

Which drugs may be prescribed to control seizures?

a. Intermediate-acting barbiturates
b. Long-acting barbiturates
c. Short-acting barbiturates
d. Ultra–short-acting barbiturates

Answer 276

b. Long-acting barbiturates, such as phenobarbital, are used to control seizures. Intermediate-acting barbiturates, such as butobarbital, use useful to sustain sleep. Short-acting, such as secobarbital, may be used for sedation. Ultra-short-acting barbiturates, such as methohexital sodium, are used for anesthesia induction.

Question 277

A client returns to the unit after having surgery with spinal anesthesia. Which action(s) would be best for the nurse to take to decrease the possibility of spinal headache? (Select all that apply.) a. Administer morphine 1 to 2 mg intravenously (IV).

b. Ambulate the client as soon as she regains sensation.
c. Encourage the client to stay flat in bed. d. Increase fluid intake. e. Position the patient in high-Fowler’s position.

Answer 277

c, d. Postdural-puncture headache can occur because of a decrease in pressure due to fluid leakage from the cerebrospinal space. Maintaining the client flat in bed for 24 to 48 hours and encouraging adequate oral fluid intake as tolerated may help prevent a spinal headache. The client may also re-quire IV fluids to supplement oral intake.

Question 278

The client who will be receiving spinal anesthesia for surgery is positioned with the back arched. The client asks “Why do I have to sit a certain way? Why can’t I just be comfortable?” Which statement would be best for the nurse to provide to the client?

a. “It is easier for the anesthesiologist if you sit this way.”
b. “Because of your age, you have to sit straight up.”
c. “The anesthesia is injected in a specific area so it distributes evenly.”
d. “You can sit however you like.”

Answer 278

c. By explaining the reason for positioning (either seated with an arched back or fetal position), the client will feel more control. The nurse can reassure the client that assistance in her maintaining the proper position will be provided.

Question 279

The client is postoperative day 3 from major orthopedic surgery and is unable to sleep. If nonpharmacologic measures have not been effective, what drug does the nurse anticipate may be ordered?
a. Flumazenil b. Phenobarbital c. Triazolam d. Zolpidem

Answer 279

d. Zolpidem may be ordered. It is a nonbenzodiazepine for short-term treatment of insomnia. Flumazenil is an antidote for benzodiazepine overdose. Phenobarbital, a long-acting barbiturate, is used to treat seizures. Triazolam is a benzodiazepine. While this class of drug can help with insomnia, a nonbenzodiazepine is a better choice.

Question 280

Which type(s) of anesthesia is/are administered using lidocaine? (Select all that apply.)

a. General
b. Inhaled
c. Intravenous
d. Local
e. Spinal

Answer 280

d, e. Lidocaine is used for local and spinal anesthesia that has a rapid onset with its effects long-lasting.

Question 281

The client works 12-hour night shifts one week and 12-hour day shifts the next week. the client tells the nurse that “some kind of sleeping pill from the drugstore” is used to help with sleep. What does the nurse suspect is the most likely main ingredient in the over-the-counter sleep drug?
a. Antihistamines b. Barbiturates c. Benzodiazepines d. Opioid agonists

Answer 281

a. Antihistamines, such as diphenhydramine, are the primary ingredient in over-the-counter sleep aids.

Question 282

The 71-year-old client presents to the health care provider with complaints of inability to go to sleep and inability to stay asleep. Which question(s) will the nurse ask to further evaluate the complaint? (Select all that apply.)

a. “What are your bedtime routine?”
b. “How many caffeinated beverages do you drink per day?”
c. “Do you take naps?”
d. “Do you sleep with the windows open?”
e. “Are you taking diuretics?”

Answer 282

a, b, c, e. Older clients may have more problems with Stage 3 and Stage 4 nonrapid eye movement (NREM) sleep and awaken frequently. Establishing a bedtime routine, maintaining a schedule of going to bed and arising in the morning, and avoiding caffeine and alcohol at bedtime may help. Al-though it sounds intuitive to take naps, they may hinder a client from obtaining a good night’s sleep if the naps last longer than 20–30 minutes. Diuretics should be taken in the morning and fluids should be limited at bedtime to prevent frequent trips to the bathroom, which may interrupt sleep.

It is strongly recommended that the patient check with the health care provider before taking ______________ products

Answer 291

over-the-counter

Question 292

Administration of phenytoin via the (oral/intramuscular/intravenous) route is not recommended because of its erratic absorption rate. (Circle correct answer.)

Answer 292

intramuscular

Question 293

The client with a history of bipolar disorder recently experienced tonic-clonic seizures. Which drug would the nurse expect to be prescribed for this client? (Select all that apply.) a. Carbamazepine

b. Diazepam
c. Ethosuximide
d. Acetazolamide

Answer 293

a, b. Carbamazepine and diazepam are given for tonic-clonic seizures. Ethosuximide and acetazolamide are indicated for absence seizures.

Question 294

The client has a seizure disorder and has just dis-covered that she is pregnant. At her first prenatal visit, she tells the nurse, “I quit taking all of my drugs because I don’t want anything to be wrong with my baby.” What is the nurse’s best response? a. “You can’t do that. You have to take your medications.”

b. “What drugs have been prescribed for you?”
c. “How long have you had seizures?”
d. “When was your last seizure?”

Answer 294

b. Although it is important to know the client’s medical history regarding seizures, the best response is asking about the drugs that have been prescribed. Most Antiseizure drugs have terato-genic properties. Women with seizure history are at increased risk for seizures during pregnancy. The risk versus the benefits need to be discussed. Abruptly stopping Antiseizure drugs can also in-crease the risk of seizures.

Question 295

Which anticonvulsant(s) is/are appropriate for status epilepticus? (Select all that apply.)

a. Fosphenytoin
b. Carbamazepine
c. Phenobarbital
d. Diazepam
e. Topiramate

Answer 295

a, c, d. Hydantoins, such as Fosphenytoin, barbiturates, such as phenobarbital, and benzodiazepines, such as diazepam or lorazepam are used for status epilepticus. Diazepam is the drug of choice. Carbamazepine and topiramate are indicated for tonic-clonic and partial seizures.

Question 296

The client has just been diagnosed with epilepsy and will be starting phenytoin. The client’s spouse asks how this drug works in the body. What is the nurse’s best response?

a. “It inhibits the enzyme that destroys one of the neurotransmitters.”
b. “It helps stop the entry of sodium into the cell.”
c. “It has not been determined exactly how it prevents seizures.”
d. “It increases the amount of calcium that enters the cell.”

Answer 296

b. Phenytoin prevents sodium from entering the cells. This reduces the activities of cells. Antiseizure drugs inhibit neurotransmitters; they do not destroy them. Antiseizure drugs suppress entry of calcium; they do not increase the influx.

Question 297

The client has just been diagnosed with a seizure disorder and has been started on valproic acid. What statement(s) by the client indicate(s) to the nurse more instruction regarding the drug is needed? (Select all that apply.)

a. “I just have to remember to take it once a day.”
b. “I do not have to worry about labs.”
c. “I need to take it at the same times every day.”
d. “This drug will cure my seizures.”

Answer 297

a, b, d. Valproic acid is taken in divided doses. Doses start at 10–15 mg/kg/day and increase to a maximum of 60/mg/kg/day until seizures are controlled. Frequent labs are needed to monitor serum levels and liver functions. Antiseizure drugs control the frequency and severity of seizures, it does not cure.

Question 298

The nurse has received an order to administer an initial dose of intravenous (IV) phenytoin to a client with new-onset seizures. What will the nurse check before administering the first dose? (Select all that apply.)

a. Hourly urine output
b. Blood glucose levels
c. Cardiac rhythm
d. Blood pressure measurements

Answer 298

b, c, d. An absolute contraindication is heart block and bradycardia. Cautious use is recommended for clients with hypoglycemia and hypotension. Dilantin is excreted in small amounts in the urine. Urine output should be monitored afterward, but not hourly.

Question 299

The client receiving intravenous (IV) phenytoin for grand mal seizures complains of burning at the IV site. What is the nurse’s best action?

a. Call the health care provider immediately to change the drug to oral.
b. Continue the infusion and reassure the patient.
c. Flush the line with 10 mL of normal saline and continue the infusion.
d. Discontinue the IV and restart the IV infusion at a different site.

Answer 299

d. Intravenous phenytoin is irritating to the tissue, and the nurse should discontinue the IV and restart the infusion at a different site. It is recommended that a central line or peripherally inserted central catheter (PICC) line be utilized when possible. The health care provider does not need to be notified immediately to change the medication to oral form. Continuing the infusion, even with a saline flush, may cause sloughing of the tissue.

Question 300

A client was started on an Antiseizure drug for a seizure disorder of unknown cause and asks how
long the drug will need to be taken. Which response is appropriate by the nurse?
a. “You will need to take an anticonvulsant of some type for your lifetime.”
b. “This drug should be taken until you haven’t had a seizure for a month.”
c. “Seizures are unpredictable and so is the duration of the treatment.”
d. “You will only need to take it for a short period of time because antiseizures will cure the seizure disorder.”

Answer 300

a. Although a variety of antiseizures may be utilized over a client’s lifetime, at this time, there is no cure for seizure disorders. The client will most likely need to take an Antiseizure for one’s lifetime.

Question 301

Which result is within the therapeutic range for phenytoin? a. 8 mcg/mL of bound phenytoin

b. 18 mcg/mL of bound phenytoin
c. 28 mcg/mL of unbound phenytoin
d. 38 mcg/mL of unbound phenytoin

Answer 301

b. 18 mcg/mL is within the therapeutic range of 10 to 20 mcg/mL for bound phenytoin and 1 to 2 mcg/ mL for unbound/free drugs. 8 mcg/mL is below the therapeutic range and the client may be at risk for seizure. 28 and 38 mcg/mL are too high, drug toxicity can occur.

Question 302

Which information would the nurse document after witnessing a client having seizure?? (Select all that apply.)

a. Types of movements
b. Duration of movements
c. Ability to stop movements
d. Progression of movements
e. Preceding events

Answer 302

a, b, d, e. Documenting the types of movements (tonic/clonic), the duration of seizure activity, and the locations where the movements started and progressed are important pieces of gathering the history of the seizure event. It is important to know, if possible, what the client had been doing before the event and if the client reported any warning before the seizure. The client is unable to stop true seizure activity voluntarily.

Question 303

The nurse is preparing discharge teaching for a client who has been started on phenytoin for a seizure disorder. Which information about the side effects of this drug will the nurse provide to the client and family member?

a. “There may be a green discoloration of the patient’s urine.”
b. “It is best to use a hard-bristle toothbrush for dental care.”
c. “Nosebleeds and sore throats should be reported to the health care provider.”
d. “The patient should get up slowly to prevent fainting.”

Answer 303

c. Nosebleeds and sore throats may be a sign of blood dyscrasias and should be reported to the health care provider. A reddish pink discoloration of the urine may be expected. To prevent injury to the gums, a soft toothbrush should be utilized. Orthostatic hypotension is not associated with phenytoin use.

Question 304

Which effect would the nurse expect to see if the client is experiencing a common side effect of phenytoin?

a. Gingival hyperplasia
b. Excessive thirst
c. Weight gain
d. Muscle tremors

Answer 304

a. Gingival hyperplasia is a common side effect of phenytoin. Excessive thirst and weight gain are not common with phenytoin.

Question 305

A client presents to the emergency department in status epilepticus. Which drug would the nurse anticipate being ordered first?

a. Diazepam
b. Midazolam
c. Propofol
d. Phenobarbital

Answer 305

a. The first-line drug of choice for status epilepticus is diazepam. Midazolam, Propofol, and high-dose phenobarbital are administered for continued seizures

Question 306

Which statement(s) is/are true about seizures and Antiseizure uses in pregnancy? (Select all that apply.)

a. Seizures may increase up to 33% in women with history of seizures.
b. Many Antiseizure drugs have teratogenic properties.
c. Antiseizure drug use increases the loss of folic acid.
d. Antiseizure drugs increase the effects of vitamin K.
e. Valproic acid causes malformation in 40% to 80% of fetuses.

Answer 306

a, b, c. Up to 33% of women with history of seizures can have increased seizure activity during pregnancy. Many Antiseizure drugs have teratogenic properties. Antiseizure drugs increase the excretion of folic acid; therefore, pregnant individuals should take daily folate supplement. Anti-seizure drugs inhibit vitamin K, contributing to bleeding.

Question 307

Which Antiseizure drug may also be used as prophylaxis for migraine headaches?

a. Diazepam
b. Phenytoin
c. Valproic acid
d. Clorazepate

Answer 307

c. Valproic acid and topiramate are indicated for migraine. Diazepam can be used additionally to those with spasms, anxiety, and alcohol withdrawal. Clorazepate can be used for anxiety and alcohol withdrawal.

Question 318

An example of a Food and Drug Administration (FDA)–approved anticholinergic drug used for Parkinson disease is __________________.

Answer 318

trihexyphenidyl (also benztropine)

Question 319

A client taking carbidopa-levodopa tablets for parkinsonism is complaining of dizziness, diarrhea, anxiety, and nasal stuffiness. Which complaints would the nurse recognize as a possible side effect of carbidopa-levodopa?

a. Dizziness
b. Diarrhea
c. Anxiety
d. Nasal stuffiness

Answer 319

a. Dizziness is a common side effect of carbidopa-levodopa. Constipation is a side effect, not diarrhea. Anxiety and nasal stuffiness are not a side effect of carbidopa-levodopa

Question 320

The nurse is teaching a client with parkinsonism about extended-release carbidopa-levodopa. Which statement(s) by the client indicate(s) the need for further teaching? (Select all that apply.)

a. “This drug may make my movements smoother.”
b. “My skin may turn yellow if I miss too many doses.”
c. “If I have trouble swallowing, I can crush my drug and mix it with applesauce.”
d. “I must take this medicine on an empty stomach.”
e. “I need to check my blood sugar regularly while taking this drug.”

Answer 320

b, c, d, e. Carbidopa-levodopa may make the client’s movements smoother, although at high doses, dyskinesia may be noted. Jaundice will not result from missing doses. Extended release drugs should not be crushed or cut; if the client is unable to swallow tablets, then other preparations, such as liquid or oral disintegrating tablets, are available. Nausea and vomiting are side effects, so taking the drug with meals may be beneficial. There is no indication that carbidopa-levodopa affects glucose levels.

Question 321

The nurse is helping a family prepare for a grocery shopping trip for a client who has been prescribed selegiline for Parkinson disease. Which food(s) should be avoided? (Select all that apply.)

a. Aged cheeses
b. Chocolate
c. Peanut butter
d. Wheat bread
e. Yogurt

Answer 321

a, b, e. Tyramine rich foods should be avoided, such as, aged cheeses, chocolate, and yogurt. These foods should be avoided when taking selegiline to prevent a hypertensive crisis from occurring. Peanut butter and wheat bread are not high in tyramine.

Question 322

A client with Alzheimer disease is taking rivastigmine and has also been started on a drug for de-pression. Which order will the nurse question be-fore administering the new drug?

a. Atypical antidepressant
b. Monoamine oxidase inhibitor (MAOI) antidepressant
c. Selective serotonin reuptake inhibitor (SSRI) antidepressant
d. Tricyclic antidepressant

Answer 322

d. An order for tricyclic antidepressant should be questioned. Tricyclic antidepressants decrease the effect of rivastigmine.

Question 323

A client with parkinsonism currently takes carbidopa-levodopa, and the client’s health care provider adds entacapone to the drug regimen. Which change in the dosing of carbidopa-levodopa would the nurse expect to occur?

a. There should be no change in the drug dosage.
b. Both carbidopa and levodopa dosages should be decreased.
c. Only the levodopa dosage should decrease.
d. Only the carbidopa dosage should decrease.

Answer 323

c. The nurse understand that levodopa only will be decreased. When taken with levodopa, COMT inhibitors like entacapone will increase the levodopa combination in the brain.

Question 324

Anticholinergics are contraindicated for which client?

a. A client with glaucoma
b. A client with shingles
c. A client with urinary frequency
d. A client with diabetes
e. A client with angina

Answer 324

a. Anticholinergic drugs are contraindicated in persons with glaucoma. Extreme caution is warranted for persons with heart problems and those with urinary retention, not urinary frequency. Shingles and diabetes are not contraindications.

Question 325

A client with a history of Parkinson disease is brought into the emergency department after the family reports the client is talking to “rabbits coming out of the walls” at home. Which drug does the nurse suspect may have caused this symptom? (Select all that apply.)

a. Bromocriptine mesylate
b. Selegiline hydrochloride
c. Pramipexole dihydrochloride
d. Tolcapone

Answer 325

a, c. Even though most drugs for Parkinson disease can cause hallucinations, they are more common with bromocriptine and pramipexole.

Question 326

A client’s wandering and hostility levels have increased per family reports. Which dosing information would concern the nurse in this client who is taking memantine 10 mg/day?
a. The dose is too high a daily dose to maintain mental status.
b. The client has taken an overdose of the drug.
c. The client is not taking enough of the drug.
d. A combination of memantine and amantadine
may be needed.

Answer 326

c. Memantine is prescribed for the treatment of mild to severe Alzheimer disease. Increased wandering and hostility can indicate that the disease is progressing and an increase in the dose may be beneficial. The maximum dose for memantine is 20 mg per day.

Question 327

Which statement by the client indicates an under-standing of how to relieve some of the side effects associated with the use of benztropine mesylate?

a. “I can suck on hard candy or chew sugarless gum to prevent dry mouth.”
b. “I need to take my drug every 6 hours so I don’t get constipated.”
c. “I should decrease the doses of all of my other drugs so I don’t get dizzy.”
d. “I should urinate after meals so I do not retain urine.”

Answer 327

a. Sucking on hard candy or chewing sugarless gum may help with dry mouth associated with anticholinergic drugs such as benztropine mesylate. This drug is initially taken at bedtime and twice per day in divided doses as a maintenance dose. The nurse should remind the client that all drug adjustments need to be made by the health care provider. Urinary retention is a side effect of anticholinergic drugs; however, the nurse should encourage the client to urinate when the urge is felt and not on a set schedule.

Answer 332

decrease; increase

Question 333

Identify the affected neuromuscular site(s) for each of the autoimmune neuromuscular disorders and the drugs to treat the disorders.

Myasthenia gravis

Answer 333

Myasthenia gravis is an autoimmune disorder that involves an antibody response against acetylcholine receptor (AChR) sites, eventually destroying the receptor sites for acetylcholine (Ach). Drugs used to treat myasthenia gravis (MG) are the acetylcholinesterase (AChE) inhibitors (cholinesterase inhibitors and anticholinesterase), such as neostigmine or pyridostigmine. They inhibit the action of AChE, which allows more activation of the cholinergic receptors.

Question 334

Multiple sclerosis

Answer 334

Multiple sclerosis (MS) is an autoimmune disorder that attacks the myelin sheath of the nerve fibers of the central nervous system, resulting in plaques. Drugs used to treat MS include corticosteroids and immunomodulators, such as teriflunomide, alemtuzumab, and glatiramer acetate.

Question 335

The nurse is assessing a client who is receiving treatment for myasthenia gravis with pyridostigmine. Which clinical manifestations would be
noted if the drug is working? 
a. Increased salivation 
b. Maintenance of muscle strength 
c. Miosis 
d. Tachycardia

Answer 335

b. Pyridostigmine increases muscle strength in clients with myasthenia gravis. Increased salivation and miosis are signs and symptoms of overdose. Bradycardia, not tachycardia can be an adverse drug effect.

a. Anxiety disorders
b. Depressive disorders
c. Psychotic disorders
d. Psychosomatic disorders

Answer 346

c. Neuroleptics are considered antipsychotics that modify psychotic behaviors and exert antipsychotic effects. Anxiolytics treat anxiety and insomnia. Antidepressives treat depressive disorders; anti-psychotics worsen depression.

Question 347

A client who was started on antipsychotic drugs asks the nurse when the drug will take effect. Which response is best by the nurse?

a. “It may take up to one week to start to feel the full effects.”
b. “Responses vary, but it may be about 6 weeks.”
c. “You will only feel better when you start psychotherapy, too.”
d. “You should start to feel better within 30-60 minutes.”

Answer 347

b. The nurse should inform the client that antipsychotic drugs can take 3 to 6 weeks before full therapeutic effects occur. While psychotherapy may help, it is not required for antipsychotics to have therapeutic effects. While the onset may be minutes to hours, its full therapeutic effect does occur until weeks later.

Question 348

a. “A therapeutic response to this drug will be immediate.”
b. “Change positions slowly from sitting to standing to prevent orthostatic hypotension.”
c. “It is all right to have alcohol when taking this drug.”
d. “This drug may be stopped abruptly as soon as your pain stops.”

Answer 348

b. Orthostatic hypotension may occur with phenothiazines and nonphenothiazines drugs within this class. The client should be encouraged to change positions slowly to prevent orthostatic hypotension. Clients should abstain from alcohol while on antipsychotics, it can worsen drowsiness, dizziness, and hypotension. Any antipsychotics should not be abruptly stopped.

Question 349

Typical antipsychotics may cause extrapyramidal symptoms (EPS) or pseudo parkinsonism. Which symptom is considered an extrapyramidal symptom?

a. Downward eye movement
b. Intentional tremors
c. Loss of hearing
d. Shuffling gait

Answer 349

d. Pseudoparkinsonism, major side effect of typical antipsychotics, are symptoms similar to Parkinson disease. Shuffling gait is one example of EPS. Other EPS include masklike facies, rigidity, tremors at rest (not intentional tremors), pill-rolling, motions of the hands, and bradykinesia.

Question 350

Which drug would the nurse expect to give to decrease extrapyramidal symptoms (EPS)?

a. Benztropine
b. Bethanechol
c. Buspirone hydrochloride
d. Doxepin

Answer 350

a. Benztropine, an anticholinergic antiparkinsonian drug. Bethanechol is an antispasmodic for urinary retention. Buspirone is an anxiolytic. Doxepin is an antidepressant.

Which drug would the nurse expect to administer to a young client with enuresis?
a. Citalopram b. Fluvoxamine c. Imipramine d. Sertraline

Answer 363

c. Imipramine, a tricyclic antidepressant (TCA) is also indicated for enuresis, involuntary urination while sleeping.

Question 364

The client has been taking phenelzine for several months for depression, which has not improved. Which dose is the maximum daily dose for this drug?
a. 15 mg/day b. 45 mg/day c. 60 mg/day d. 90 mg/day

Answer 364

d. The maximum daily dose of phenelzine is 90 mg. The initial dose is 15 mg/day in three divided doses.

Question 365

The client has been prescribed amitriptyline as an adjunct to therapy for depression. Which information will the nurse include in the health teaching regarding this drug?

a. “Check your heart rate daily. It may become very slow.”
b. “Stand up slowly because your blood pressure can drop suddenly.”
c. “You should start to feel less depressed within 12 hours.”
d. “Take your drug in the morning because it will make you alert.”

Answer 365

b. Orthostatic hypotension is a frequent side effect of tricyclic antidepressants (TCAs). The client should be encouraged to change positions slowly to avoid this side effect. Amitriptyline can cause tachycardia, not bradycardia. The onset of amitriptyline is 1-3 weeks, not 12 hours. Since amitriptyline has an anticholinergic action, it should be taken at night, not during the day.

Question 366

Which food(s) or beverage(s) is/are contraindicated in a client that is prescribed isocarboxazid? (Select all that apply.) a. Bananas b. Chocolate c. Chicken d. Milk e. Wine

Answer 366

a, b, e. Foods high in tyramine, such as bananas, chocolate, and wine are contraindicated in a client who is taking a monoamine oxidase inhibitor (MAOI), such as isocarboxazid. Other foods that are high in tyramine include aged cheeses, processed meats, and soybeans or soy products. These foods have sympathomimetic-like effects and can cause hypertensive crisis.

Question 367

A client who has been taking fluoxetine and “some herb” for depression is complaining of a severe headache. The client is diaphoretic and restless. Which herb does the nurse suspect the client has been taking?

a. Ephedra
b. Ginseng
c. Garlic
d. St. John’s wort

Answer 367

d. St. John’s wort is a common herbal remedy for depression. St. John’s wort, when taken in com-bination with selective serotonin reuptake inhibitor (SSRI) drugs, such as fluoxetine, can precipitate serotonin syndrome, which presents as headache, sweating, and agitation. Ephedra and ginseng can cause palpitations, heart attack, and hypertensive crisis when taken with MAOIs, not SSRIs.

Question 368

Which effect is an advantage of taking selective serotonin reuptake inhibitors (SSRIs) over tricyclic antidepressants (TCAs)?

a. Fewer sexual side effects
b. Increased appetite
c. Less sedation
d. Less tachycardia

Answer 368

c. SSRIs has less sedative effect. They also do not cause hypotension, anticholinergic effects, or cardiotoxicity. However, SSRIs can cause sexual dysfunction.

Question 369

Which nursing intervention is most important for a client taking lithium?

a. Advising the client that the drug can be stopped when not in a manic phase
b. Emphasizing the importance of client-adjusted dosage
c. Monitoring for excessive thirst, weight gain, and increased urination
d. Teaching the client to limit fluid intake to prevent weight gain

Answer 369

c. Monitoring the client is one of the most important roles of the nurse. Trending vital signs, weight, and lab work will be important to the client’s ongoing care. The client needs to maintain a fluid intake of 2–3 L of fluid/day initially and must be especially vigilant to maintain an adequate intake in hot weather. Clients during manic phase frequently stop taking their drug when they feel better. They must be advised to continue taking the drug even if they feel better.

Question 370

The client is currently taking lithium for bipolar disorder, manic phase. Which laboratory value would the nurse monitor?

a. BUN
b. Blood glucose
c. INR
d. Platelet count

Answer 370

a. Monitoring hepatic and renal function in a client taking lithium should be completed with weekly blood work, which includes BUN and creatinine level measurements.

Question 371

The client has been taking lithium 1800 mg/day in three divided doses for 10 days. The client remains agitated and hyperactive, with a lithium level of 0.7 mEq/L. Which client condition would the nurse suspect is occurring?

a. The patient is experiencing lithium toxicity.
b. The patient’s lithium level is subtherapeutic.
c. The patient’s lithium level is therapeutic.
d. The patient is allergic to lithium.

Answer 371

b. The client’s lithium level is still subtherapeutic, and he remains in a manic phase. Therapeutic range for lithium is 0.8 to 1.2 mEq/L.

Question 372

The nurse is teaching the client about lithium. Which statement by the client indicates a need for more education? a. “I can stop my drug if I have not been manic for 2 weeks.”

b. “I should avoid caffeine products that may aggravate the manic phase.”
c. “I should take my drug with food.”
d. “It is important that I wear or carry ID indicating that I am taking lithium.”

Answer 372

a. The client needs further education requiring the purpose of the drug. Lithium may be used in bipolar disorder as a mood stabilizer, but its effect is on the manic phase. The drug should be taken with food. Tyramine rich foods, such as caffeine should be avoided.

Question 373

The client has been prescribed venlafaxine for generalized anxiety disorder. Which statement by the client indicates the need for further health teaching?

a. “I need to take my drug even if I am not feeling anxious.”
b. “I need to wear sunscreen when I am outdoors.”
c. “If I have any issues with my sexual performance, I can ask my health care provider.”
d. “It is OK if I keep taking my herbal drugs for my depression and anxiety.”

Answer 373

d. Venlafaxine is a serotonin-norepinephrine reup-take inhibitor (SNRI). Side effects of venlafaxine may include drowsiness, insomnia, photosensitivity, and ejaculatory dysfunction, among others. Taking St. John’s wort while taking venlafaxine increases the risk of serotonin syndrome or neuroleptic malignant syndrome.

Question 374

The client with a history of bipolar disorder and is taking lithium is considering pregnancy. Which teratogenic effects can occur when taking lithium while pregnant? (Select all that apply.)

a. Congenital anomaly
b. Excessive weight gain
c. Hyperemesis gravidarum
d. Heart defects
e. Multiple gestation

Answer 374

a, d. Some studies have linked lithium to a congenital anomaly involving the tricuspid valve of the heart if taken during the first trimester of pregnancy.

Question 375

Answer 375

injury; infection

Question 376

The five cardinal signs of inflammation are ________________, ________________, ________________, ________________, and ________________.

Answer 376

redness (erythema); swelling (edema); heat; pain; loss of function

Question 377

Leukocyte infiltration of the inflamed tissue occurs during the ________________ phase of inflammation.

Answer 377

delayed

Question 378

The half-life of each NSAID (does/does not) differ greatly. (Circle correct answer.)

Answer 378

does

Question 379

When using NSAIDs for inflammation, the dosage is generally ________________ than that for pain relief

Answer 379

higher (or increased)

Question 380

Corticosteroids are indicated to control __________ flareups.

Answer 380

arthritic

Question 381

Which body response occurs during the vascular phase of inflammation?

a. Leukocyte and protein infiltration into inflamed tissue
b. Vasoconstriction with leukocyte infiltration into inflamed tissue
c. Vasoconstriction and fluid influx into the interstitial space
d. Vasodilation with increased capillary permeability

Answer 381

d. The vascular phase of the inflammation is associated with vasodilation and increased vascular permeability. This allows leukocyte and other sub-stances to filter into the inflamed tissue.

Question 382

A client who is taking nonsteroidal anti-inflammatory drugs (NSAIDs) for arthritis complains of persistent heartburn.
What further question(s) should the nurse ask the client about the heartburn?
(Select all that apply.)
a. “Do you take your drug with food?” b. “Have you been drinking an increased amount of water?”
c. “Have you noticed a change in the color of your bowel movements?”
d. “What dosage of the NSAID are you taking?”
e. “Where is the heartburn located?”

Answer 382

a, c, d, e. Heartburn can be a side effect of NSAIDs. Taking NSAIDs with food may help decrease heartburn. Dark, tarry, or bloody bowel movements are an indication of GI bleeding, which is an adverse effect of NSAID use. The dosage range for NSAIDs varies from drug to drug, but large doses may cause erosive esophagitis, which would cause indigestion-type pain. There are many types of heartburn, including those associated with acute myocardial infarction. Not all heartburn is of GI origin attributable to a drug effect.

Question 383

When preparing discharge teaching for a client who has been prescribed ibuprofen for arthritis, Which statement would the nurse provide to the client on the mechanism of action?

a. “Ibuprofen is a COX-2 inhibitor, so it blocks prostaglandin synthesis.”
b. “Ibuprofen inhibits prostaglandin synthesis.”
c. “Ibuprofen binds with opiate receptor sites.”
d. “Ibuprofen promotes vasodilation to increase blood flow.”

Answer 383

b. NSAIDs inhibit the production of prostaglandin, thereby, decreasing inflammation and pain. Ibuprofen is not a COX-2 inhibitor. Ibuprofen does not bind to opiate receptor sites and it does not pro-mote vasodilation.

Question 384

A client with a complicated medical history including hypertension, atrial fibrillation, and arthritis calls the health care provider’s office to speak with a nurse about “all of these bruises I have all of a sudden.” Which potential drug interaction should concern the nurse with these symptoms? a. Aspirin and warfarin

b. Sulfasalazine and acetaminophen
c. Tolmetin and propranolol
d. Meloxicam and amlodipine

Answer 384

a. Warfarin is an anticoagulant that may be taken by clients with atrial fibrillation. Aspirin displaces warfarin from its protein-binding site. This increases the anticoagulant effect and may lead to excessive bleeding, which may initially be indicated by bruising. Although the other drugs may have drug-drug interactions, they do not cause in-creased anticoagulant effects, as evidenced by the bruising.

Question 385

A 4-year-old child was brought to the emergency room for continued fever despite taking aspirin. Which statement is correct about a 4-year-old receiving aspirin?

a. Aspirin has the potential to cause gastrointestinal (GI) bleeding in children.
b. Aspirin has the potential to cause ringing in the ears in children.
c. Aspirin has the potential to cause hyperglycemia in children.
d. Aspirin has the potential to cause Reye syndrome in children.

Answer 385

d. Aspirin should not be given to young children due to the risk of Reye syndrome, which can be fatal. Hypersensitivity reactions, such as ringing in the ears can occur in any person, but it is not the most concerning. Side effects, such as GI distress can occur in anyone taking NSAIDs, but it is not the most concerning.

Question 386

A client with a history of asthma has been pre-scribed sulfasalazine, a salicylate derivative, for arthritis. Which effects can salicylic acid and salicylate derivatives cause that would concern the nurse?

a. Tachycardia
b. Increased secretions
c. Bronchospasm
d. Fluid retention

Answer 386

c. Sulfasalazine, a salicylate derivative, can cause bronchospasms in a client with asthma; therefore, its use is contraindicated to those with known sensitivity.

Question 387

Which statement is correct about the positive aspect of ibuprofen in relation to other nonsteroidal anti-inflammatory drugs (NSAIDs)?

a. It tends to cause less gastrointestinal (GI) irritation.
b. It may be taken between meals.
c. It has a long half-life of 20–30 hours.
d. It has no drug-drug interactions.

Answer 387

a. Ibuprofen is a propionic acid derivative, which has a decreased risk of GI disturbances. Ibuprofen should be taken with food. It has a short half-life
and is highly protein bound. There are many drug-drug interactions. Ibuprofen can increase bleed time when taken with warfarin. When taken with aspirin, the effects of the ibuprofen are decreased.

Question 388

A client has been prescribed ibuprofen 400 mg three times a day (tid) for arthritis. Which statement by the client would indicate a need for further education?

a. “This drug may cause gastrointestinal (GI) upset.”
b. “Now I won’t have to drink so much water.”
c. “I know this drug might cause some diarrhea.”
d. “I will need to stop taking this drug if I get pregnant.”

Answer 388

b. Since ibuprofen is excreted in the urine, adequate fluid intake and urine output should be maintained. Ibuprofen can have negative consequences during early pregnancy and is contraindicated during third trimester. It can cause GI upset and diarrhea.

Question 389

What advantage does piroxicam have over other nonsteroidal anti-inflammatory drugs (NSAIDs)?

a. Piroxicam does not cause any GI irritation
b. Piroxicam has fewer drug-drug interactions
c. Piroxicam has a long half-life
d. Piroxicam has a rapid onset

Answer 389

c. Piroxicam has a long half-life (50 hours). Be-cause of its long half-life, it is taken once daily. Like other NSAIDs, it can cause GI irritation. It has many drug-drug interactions, and its onset is delayed.

Question 390

By which action does colchicine relieve the symptoms of gout?

a. Colchicine inhibits the migration of leukocytes to the inflamed area.
b. Colchicine blocks reabsorption of uric acid.
c. Colchicine blocks prostaglandin release.
d. Colchicine inhibits uric acid synthesis.

Answer 390

a. Colchicine inhibits the migration of leukocytes to the inflamed area; thereby decreasing inflammation. Colchicine does not inhibit the synthesis of uric acid nor does it block the reabsorption or re-move uric acid. Colchicine does not block the re-lease of prostaglandins.

Question 391

Which mechanism of action is primary for probenecid in the treatment of gout?

a. Probenecid is used for the retention of urate crystals in the body
b. Probenecid is used for the inhibition of the reabsorption of uric acid
c. Probenecid is used for the promotion of uric acid removal in the ureters
d. Probenecid is used for the increasing the release of uric acid

Answer 391

b. Probenecid is used for the inhibition of the reabsorption of uric acid in the kidneys; thereby, increasing the excretion. Its primary action is not the retention of urate crystals. Ureters are tubes for the pathway of urine; it is not the primary action of probenecid.

Question 392

Which describes the mechanism of action for etanercept for the treatment of severe rheumatoid arthritis?

a. Etanercept neutralizes tumor necrosis factor (TNF), thereby altering the inflammatory response.
b. Etanercept inhibits IL-1 from binding to interleukin receptor sites in cartilage and bone.
c. Etanercept blocks COX-2 receptors, which are needed for biosynthesis of prostaglandins.
d. Etanercept promotes uric acid reabsorption

Answer 392

a. Etanercept neutralizes tumor necrosis factor (TNF). This neutralizing alters the inflammatory process. Anakinra, not etanercept, inhibits IL-1 from binding to interleukin receptors found in bones and cartilages. Celecoxib inhibits COX-2 receptors to alter the inflammatory process. Uricosurics, such as probenecid, blocks the reabsorption of uric acid.

Question 393

When discontinuing steroid therapy, which time frame would the dosage be tapered?

a. No tapering is necessary
b. 1–4 days
c. 5–10 days
d. More than 10 days

Answer 393

c. Steroids should be tapered over 5-10 days.

Question 394

A client has started taking corticosteroids for an arthritic condition. Which information should the
nurse include in a health teaching plan? (Select all that apply.)
a. Corticosteroids are used to control arthritic flare-ups in severe cases.
b. Corticosteroids have a short half-life.
c. Corticosteroids are usually administered once a day.
d. Corticosteroids are tapered over the course of 5–10 days.
e. Corticosteroids may not be taken with prostaglandin inhibitors.

Answer 394

a, c, d. Corticosteroids may be used for a variety of disease processes including flare-ups of arthritic conditions. They have a long half-life and are usually taken once a day in a large prescribed dose and then the dose is tapered for 5–10 days. Lengthy corticosteroid therapy is never stopped abruptly. They may be given in combination with other drugs including prostaglandin inhibitors.

Question 395

Which information should the nurse include when teaching about antigout drug? (Select all that apply.)

a. Include large doses of vitamin C supplements.
b. Increase fluid intake.
c. Avoid alcoholic beverages.
d. Avoid foods high in purine.
e. Take the drug with food.
f. Avoid direct sunlight.

Answer 395

b, c, d, e. Fluid intake should be increased to pro-mote uric acid excretion. Avoiding alcohol is important because alcohol causes an overproduction, as well as an underexcretion, of uric acid. Purine is required to synthesize uric acid. Taking the drug with food will help avoid GI upset. Some studies have shown that vitamin C may help increase uric acid elimination; however, large doses of supple-mental vitamin C are not recommended, and since vitamin C is an acid, there is a higher risk of kidney stone formation.

Question 396

A client who has been prescribed infliximab for severe rheumatoid arthritis has developed temperature of 101.9° F, chills, nausea, vomiting, and dizziness. Which advise would the nurse provide for the client to do?

a. The nurse does not need to advise anything. These are common side effects of infliximab.
b. Instruct the client take a cool bath.
c. The client should wait 24 hours and, if symptoms continue, call the clinic back.
d. The client should contact the health care provider for further evaluation.

Answer 396

d. Although side effects of infliximab may include headache, dizziness, cough, nausea, and vomiting, an adverse reaction to the drug is severe infection attributable to immunosuppression. A fever of 101.9° F in an adult who is taking infliximab needs to be evaluated.

alcohol; cigarettes

Question 422

Phosphodiesterase inhibitors promote which actions in treating heart failure?

a. Increase serum sodium and potassium levels
b. Promote negative inotropic action
c. Promote positive inotropic action
d. Promote vasoconstriction

Answer 422

c. Phosphodiesterase inhibitors, such as milrinone, promote positive inotropic response and vasodilation, not vasoconstriction. Phosphodiesterase inhibitors do not increase serum sodium and potassium levels. Increasing serum sodium can promote water retention, which will worsen heart failure.

d. “It will slow down the speed of your heart so that it will work more effectively.”

Answer 423

d. Quinidine is a fast sodium channel blocker that decreases sodium influx into cardiac cells. The response is slowed conduction speed, suppressed automaticity, and increased repolarization time.

Question 424

Which is more effective when other drugs are ineffective in treating ventricular fibrillation.

a. Amiodarone
b. Atropine
c. Acebutolol HCl
d. Propafenone HCl

Answer 424

a. Amiodarone prolongs repolarization and is given intravenously in emergency treatment for ventricular dysrhythmias when other antidysrhythmics are not effective. Atropine is for symptomatic brady-cardia; acebutolol is for premature ventricular con-tractions and is given orally.

Question 425

What is lidocaine primarily used to treat?

a. Atrial fibrillation
b. Bradycardia
c. Complete heart block
d. Ventricular dysrhythmias

Answer 425

d. Lidocaine is used to treat ventricular dysrhythmias. Atrial fibrillation, bradycardia, and complete heart block are atrial dysrhythmias.

Question 426

A client with angina has been prescribed verapamil. Which priority teaching point(s) will the nurse include regarding this drug? (Select all that apply.)

a. “Eat lots of fiber to avoid constipation.”
b. “High blood pressure can be caused by verapamil.”
c. “This drug is taken three times per day.”
d. “Wear sunscreen due to photosensitivity.”
e. “You should not take this drug if you are diabetic.

Answer 426

a, c. Constipation is a side effect of verapamil, which is taken three times per day. Verapamil may cause hypotension, not hypertension.

Question 427

A client has been prescribed amlodipine to help control hypertension. Which laboratory values must be monitored carefully when on amlodipine?

a. Arterial blood gasses
b. Blood glucose
c. Complete blood count
d. Liver enzymes

Answer 427

d. Calcium channel blockers can affect kidney and liver function, so baseline liver enzymes and renal function should be obtained and trended.

Question 428

Abnormal levels of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) indicate which disease process?

a. Aneurysm
b. Cerebrovascular accident
c. Heart failure
d. Myocardial infarction

Answer 428

c. ANP and BNP are elevated in persons with HF. Both are secreted from the atrial cells of the heart.

Question 429

A client taking digoxin daily along with several other drugs has a brain natriuretic peptide (BNP) level of 630 pg/mL. What concerns the nurse about this level?

a. It is below the normal/reference range for her age.
b. Nothing. It is within the normal range.
c. It is slightly elevated.
d. It is markedly elevated.

Answer 429

d. Normal values are less than 100 pg/mL. Greater than 100 pg/mL is considered elevated. Older women tend to have higher normal BNP levels than older men; however, a level of 630 pg/mL is markedly elevated and is of concern for heart failure.

Question 430

The nurse knows that digitalis is usually prescribed for which abnormal rhythm?

a. Atrial fibrillation
b. Paroxysmal atrial tachycardia
c. Second-degree heart block
d. Ventricular tachycardia

Answer 430

a. Digitalis drugs, such as digoxin, can be used for heart failure or atrial fibrillation. Atrial fibrillation
is a cardiac dysrhythmia of the atria.

Question 431

What is the usual maintenance dose of digoxin? a. 0.125-5 mg/d b. 0.025-1 mg/d c. 0.05-1.75 mg/d d. 6–10 mg/d

Answer 431

a. The usual maintenance dose of digoxin is 0.125-0.5 mg/d. Answers b and c are too low and answer d is too high of a dose. The therapeutic serum level for digoxin is 0.8 to 2 ng/mL.

Question 432

A client, who has been on digoxin, presents to the clinic complaining of nausea, malaise, and “just not feeling well.” The nurse suspects digoxin toxicity. What is a therapeutic digitalis level? a. 0.15–0.5 ng/mL b. 0.8–2 ng/mL c. 2–3.5 ng/mL d. 3.5–4 ng/mL

Answer 432

b. Digoxin has a long half of 30-40 hours and has low protein-binding power of 20-30%. Because of these, drug accumulation can occur causing digoxin toxicity. Serum digoxin levels are drawn to assess for possible toxicity. The therapeutic serum level when taken for dysrhythmias is 0.8 to 2 ng/ mL. When it is taken for heart failure, the therapeutic level is 0.5 to 1 ng/mL.

Question 433

What is the antidote for digitalis toxicity?

a. Cardizem
b. Digoxin immune Fab
c. Gamma globulin
d. Protamine

Answer 433

b. Digoxin-immune Fab can be given to treat severe digitalis toxicity. This drug binds with digoxin so that it can be excreted in the urine.

Question 434

The nurse is reviewing the patient’s medication administration record (MAR). Which drug(s) on the MAR will concern the nurse, given that the patient is taking digitalis? (Select all that apply.)

a. Cortisone
b. Furosemide
c. Hydrochlorothiazide
d. Nitroglycerin
e. Potassium supplement

Answer 434

a, b, c. Cortisone, furosemide, and hydrochlorothiazide all promote loss of potassium, which increases the effect of digitalis and can lead to digitalis toxicity. A person taking a potassium-wasting diuretic or cortisol should avoid hypokalemia by eating potassium-rich foods or taking potassium supplements.

Question 435

The nurse is providing health teaching to a client prescribed digoxin for heart failure. Which food(s) will the nurse tell the client to avoid? (Select all that apply.)

a. Apples
b. Celery
c. Hot dogs
d. Lettuce
e. Potatoes

Answer 435

c. There are no specific drug-food contraindications for digoxin. The client should be encouraged to eat foods high in potassium such as fruits and vegetables (including potatoes). A client with heart failure should avoid hot dogs because of their high sodium content.

Question 436

What is the duration of action of a nitroglycerin transdermal patch?

a. 6–8 hours
b. 10–12 hours
c. 18–24 hours
d. 36–48 hours

Answer 436

c. The duration of action for NTG patch is 18-24 hours. However, clients should be instructed to remove the patch nightly to allow for an 8-12 hours nitrate-free interval to avoid building tolerance.

Question 437

Chapter 38

Question 438

Which group(s) of diuretics is/are frequently pre-scribed to treat hypertension and congestive heart failure? (Select all that apply.)

a. Carbonic anhydrase inhibitors
b. Loop diuretics
c. Osmotic diuretics
d. Potassium-sparing diuretics
e. Thiazide diuretics

Answer 438

b, d, e. Diuretics are classified according to their mechanisms of action. Loop diuretics promote the loss of potassium and sodium; potassium-sparing diuretics promote the loss of sodium while retaining potassium; and thiazide diuretics promote the loss of sodium and some potassium. All diuretics promote the loss of water. While osmotic diuretics promote the loss of water and sodium, they are not used to treat hypertension and congestive heart failure; instead, they are used to decrease edema, especially cerebral edema. Carbonic anhydrase inhibitors also promote water and bicarbonate loss with minimal influence on electrolytes. Their use is to decrease intraocular pressure, not hypertension and heart failure.

Question 439

What is the pharmacologic action of spironolactone?

a. Increase potassium and sodium excretion
b. Promote potassium retention
c. Promote potassium and calcium retention
d. Promote potassium excretion and sodium retention

Answer 439

b. Spironolactone is a potassium-sparing diuretic. It promotes potassium retention in the renal tubules.

Question 440

What is the classification of furosemide?

a. Loop diuretic
b. Osmotic diuretic
c. Potassium-sparing diuretic
d. Thiazide diuretic

Answer 440

a. Furosemide is a loop diuretic, which promotes excretion of water, sodium, and potassium, primarily in the loop of Henle and some in the distal renal tubules. Other electrolytes that are excreted include magnesium, ammonium, phosphate, and calcium.

Question 441

A client has been prescribed spironolactone 100 mg/day to treat an irregular heart rhythm. Which statement by the client indicates an under-standing of the drug teaching the nurse provided?

a. “I need sodium so my heart beats regularly.”
b. “This drug is dangerous if you have had a heart attack.”
c. “It helps keep potassium so my heart does not get irregular.”
d. “I need to take it with lots of bananas to keep my potassium up.”

Answer 441

c. Spironolactone blocks the action of aldosterone and inhibits the sodium-potassium pump, so potassium is retained. This is important in maintaining a regular cardiac rhythm. It is frequently prescribed and is not contraindicated in clients who have had a myocardial infarction. Sodium is excreted with this drug. Clients should be advised not to overindulge in foods rich in potassium such as bananas, because this could cause above-normal levels of potassium (hyperkalemia).

Question 442

The nurse has received an order to administer 40 mg of furosemide intravenously (IV) to the client. What does the nurse know about how this drug should be administered?

a. It must be mixed in 50 mL of normal saline.
b. It can only be given in a central line.
c. The patient must be on a cardiac monitor.
d. It should be given over 1–2 minutes.

Answer 442

d. To prevent hearing loss, furosemide must be administered by slow IV push over at least 1–2 minutes. It does not need to be diluted and does not require a central line for administration. Cardiac monitoring is not essential, because furosemide does not generally cause arrhythmias.

Question 443

Which lab value(s) should a nurse monitor in a client receiving chlorothiazide? (Select all that apply.)

a. Potassium
b. Sodium
c. Bicarbonate
d. Calcium
e. AST/ALT

Answer 443

a, b, d. Hypokalemia, or low serum potassium level, is a risk for clients taking thiazides. This could be a life-threatening condition. Sodium is also lost, causing hyponatremia. Calcium level is elevated be-cause thiazides block calcium excretion. There is minimal effect on bicarbonate levels. Cautious use in hepatic failure clients is recommended, but trending of AST/ALT levels is not always indicated. Baseline values may be beneficial.

Question 444

A client who has had an acute myocardial infarction has been started on spironolactone 50 mg/day. When evaluating routine laboratory work, the nurse discovers the client has a potassium level of 5.8 mEq/L. What is the priority intervention to be implemented?

a. The spironolactone dose should be held and the intake of foods rich in potassium should be restricted.
b. The spironolactone dose should be continued and the patient should be encouraged to eat fruits and vegetables.
c. The spironolactone dose should be increased and the patient instructed to decrease foods rich in potassium.
d. Instruct the patient to continue with the current dose of spironolactone and report any signs or symptoms of hypokalemia

Answer 444

a. The normal range for serum potassium level is 3.5–5 mEq/L. A level of 5.8 mEq/L is considered hyperkalemia. The dose of spironolactone may need to be held or decreased, and the client should decrease intake of potassium-rich foods such as bananas, apricots, leafy greens, and salmon.

Question 445

Which type of acid-base imbalance could occur if a patient is taking high doses of acetazolamide or uses the drug constantly?

a. Metabolic acidosis
b. Metabolic alkalosis
c. Respiratory acidosis
d. Respiratory alkalosis

Answer 445

a. Acetazolamide is a carbonic anhydrase inhibitor. It blocks the action of carbonic anhydrase, which is an enzyme that affects hydrogen ion balance. If the action is blocked, more bicarbonate will be excreted, leading to metabolic acidosis.

Question 446

The client with heart failure has been prescribed hydrochlorothiazide. Which statement by the client indicates understanding of the dosing regimen?

a. “I need to take it on an empty stomach for it to work.”
b. “I really only need to take my medicine when I am having a hard time breathing.”
c. “It may take several weeks before it starts to work.”
d. “I should take it in the morning so I don’t have to go to the bathroom at night.”

Answer 446

d. Because the onset of action HCTZ is 2 hours, it may be best to take the drug when the client will be awake for several hours so sleep is not disturbed. Hydrochlorothiazide can be taken with food to prevent GI upset. The drug needs to be taken consistently, even if the client is not having symptoms of heart failure.

Question 447

The client with a complicated medical history including heart failure, cardiac arrhythmias, arthritis, and depression was started on furosemide for heart failure. Which drug would be of major concern to the nurse?

a. Amiodarone
b. Acetaminophen
c. Amitriptyline
d. Zolpidem

Answer 447

a. Furosemide will cause an increased loss of potassium (hypokalemia) when given with amiodarone, which may predispose the client to ventricular arrhythmias.

Question 448

A client taking furosemide reports being weak, having severe leg cramps, and unable to ambulate. Knowing the mechanism of action of furosemide, the nurse is concerned about which electrolyte imbalance?

a. Hyponatremia
b. Hypermagnesemia
c. Hypokalemia
d. Hyperchloremia

Answer 448

c. Muscle weakness, abdominal distention, severe leg cramping, and cardiac arrhythmias are indications of hypokalemia (low potassium levels). Low potassium levels may occur with the use of loop diuretics.

Question 449

In which client are loop diuretics contraindicated?

a. The client with anuria
b. The client with asthma
c. The client with allergy to ceftriaxone
d. The client with gastric ulcers

Answer 449

a. Loop diuretics are contraindicated in clients with anuria. Giving diuretics to a client without any urine output will not force urine production. Clients allergic to sulfa drugs should not take furosemide or bumetanide; these are derivatives of sulfonamides.

Question 450

A client diagnosed with hypertension and diabetes was started on hydrochlorothiazide. Which statement by the client indicates understanding of the drug teaching the nurse has provided?

a. “It will start working within minutes.”
b. “I don’t need to monitor my blood sugar.”
c. “I should take my drug on an empty stomach so it works better.”
d. “I need to keep track of my weight and blood pressure at home.”

Answer 450

d. Daily weights and vital signs need to be trended at home on a daily basis. The client and family should be educated on how to take these measurements or arrangements should be made for assessment by home health services, at least initially. The onset of action for hydrochlorothiazide is 2 hours. Hyperglycemia is a side effect of hydrochlorothiazide, so blood sugar level should be monitored. This medication can be taken with food to prevent nausea.

Question 451

When hypertension cannot be controlled nonpharmacological, antihypertensive drugs may be prescribed. Three of the five sympatholytic groups are ________________, ________________, and ________________.

Answer 451

beta-adrenergic blockers; centrally acting alpha2 agonists; alpha-adrenergic blockers; also adrenergic neuron blockers, alpha1-and beta1-adrenergic blockers

Question 452

Two categories of antihypertensives in addition to the sympatholytic are __________________ and _________________

Answer 452

diuretics, direct-acting arteriolar vasodilators; also ACE inhibitors, angiotensin II-receptor blockers, and calcium channel blockers

Question 453

Thiazide diuretics may be combined with other antihypertensive drugs. Examples of other antihypertensives include ________________ and ________________.

Answer 453

beta blockers; ACE inhibitors; also angiotensin II–receptor blockers, potassium-sparing diuretics, centrally acting alpha2 agonist

Question 454

Many antihypertensive drugs can cause fluid retention. To decrease body fluid, the drug group often administered with antihypertensive drugs is _______________

Answer 454

diuretics

Question 455

Beta-adrenergic blockers reduce cardiac output by diminishing the sympathetic nervous system response. With continued use of beta blockers, vascular resistance is (increased/diminished) and blood pressure is (lowered/in-creased). (Circle correct answers.)

Answer 455

diminished; lowered

Question 456

Atenolol and metoprolol are examples of (cardioselective/noncardioselective) antihypertensive drugs. (Circle correct answer.

Answer 456

cardioselective

Question 457

The alpha blockers are useful in treating hypertensive patients with lipid abnormalities. The effects they have on lipoproteins include (decreased/increased) VLDL and LDL; and (decreased/increased) HDL. (Circle correct answers.)

Answer 457

decreased; increased

Question 458

Which client would be most suited for treatment with a nonselective alpha-adrenergic blocker?

a. A client with mild to moderate renal failure
b. A client with hypertension associated with pheochromocytoma
c. A client with hyperlipidemia
d. A client with type 2 diabetes

Answer 458

b. Nonselective alpha-adrenergic blockers are used for severe hypertension associated with pheochromocytomas (catecholamine-secreting tumors of the adrenal medulla).

Question 459

Where in the body do direct-acting vasodilators act to decrease blood pressure?

a. Cardiac valves
b. Dopaminergic receptors in kidneys
c. Renal tubules
d. Smooth muscles of the blood vessels

Answer 459

d. Direct-acting vasodilators relax the smooth muscles of the blood vessels, mainly the arteries, resulting in vasodilation. This promotes blood flow to the brain, kidneys, and other vital organs. Vasodilation causes the blood pressure to decrease.

Question 460

With use of direct-acting vasodilators, sodium and water are retained and peripheral edema occurs. Which category of drugs should be given to avoid fluid retention?

a. Anticoagulants
b. Antidysrhythmics
c. Cardiac glycosides
d. Diuretics

Answer 460

d. Diuretics are frequently given with a variety of antihypertensive to decrease fluid retention and peripheral edema.

Question 461

Which is/are action(s) of angiotensin II–receptor blockers (ARBs)? (Select all that apply.)

a. Block angiotensin II
b. Cause vasodilation
c. Decrease peripheral resistance
d. Increase sodium retention
e. Slow heart rate

Answer 461

a, b, c. Angiotensin II binds to cell receptors to in-crease blood pressure. Angiotensin II also causes vasoconstriction and increases vascular resistance. ARBs inhibit the binding of angiotensin II at receptor sites; thereby, decreasing blood pressure. With-out the binding, vasoconstriction does not occur and the peripheral resistance is not increased. ARBs do not increase sodium retention or decrease heart rate.

Question 462

An angiotensin II–receptor blocker (ARB) can be combined with the thiazide diuretic hydrochlorothiazide. What is the purpose of combining these two drugs?

a. To decrease rapid blood pressure drop
b. To enhance the antihypertensive effect by promoting sodium and water loss
c. To increase sodium and water retention for controlling blood pressure
d. To promote potassium retention

Answer 462

b. ARBs inhibit the binding of angiotensin II to receptor sites; thereby blood pressure does not increase. Diuretics, such as thiazides, assist in lowering blood pressure by promoting water and sodium loss.

Question 463

Angiotensin II–receptor blockers (ARBs) may be prescribed for hypertensive clients instead of an angiotensin-converting enzyme (ACE) inhibitor. What is the most limiting factor in the use of ACE inhibitors?

a. Coughing
b. Dizziness
c. Shortness of breath
d. Sneezing

Answer 463

a. The primary side effect of ACE inhibitors is a constant, irritated cough and may be relieved upon discontinuation of the drug. ARBs do not have the side effect of coughing.

Question 464

A nurse is preparing to administer cardiac drugs to several clients. The nurse would be concerned about administering an ACE inhibitor as a mono-therapy to which client?

a. A Hispanic client
b. An Asian client
c. A Caucasian client
d. A African American client

Answer 464

d. African Americans are not as responsive to ACE inhibitors as monotherapy but may respond better if they are combined with a diuretic.

Question 465

A African American client presents to a health care provider for continued high blood pressure. Which group of drugs would be more effective for this client?

a. Angiotensin II blockers
b. Beta blockers
c. Calcium blockers
d. Direct renin inhibitor

Answer 465

c. Calcium channel blockers and alpha1 blockers may be more effective in African American clients for treating hypertension. They do not respond well to direct renin inhibitors, beta blockers, and ACE inhibitors. ARBs have similar mechanism of actions as ACE inhibitors, affecting the RAAS.

Question 466

Which drug-herb interaction can occur when Mahuang (ephedra) is taken concomitantly with an antihypertensive drug?

a. A decrease or counteraction of the effects of the antihypertensive drug
b. A decrease in the hypertensive state
c. An increase in the hypotensive effects of the antihypertensive drug
d. No effect on the action of the antihypertensive drug

Answer 466

a. Mahuang decreases or counteracts the effects of antihypertensives and can even increase the hypertensive state.
