The nurse is monitoring a patient who is experiencing severe ethanol withdrawal. Which are signs and symptoms of severe ethanol withdrawal (Select all that apply.)
Agitation Drowsiness Tremors Systolic blood pressure higher than 200 mm Hg Temperature over 100° F (37.7° C) Pulse rate 110 beats/min
Agitation
Tremors
Systolic blood pressure higher than 200 mm Hg
Signs and symptoms of severe ethanol withdrawal (delirium tremens) include systolic blood pressure higher than 200 mm Hg, diastolic blood pressure higher than 140 mm Hg, pulse rate higher than 140 beats/min, temperature above 101° F (38.3° C), tremors, insomnia, and agitation. See Box 17-6 for all signs and symptoms of ethanol withdrawal.
The nurse is monitoring drug levels for a patient who is receiving theophylline. The most recent theophylline level was 22 mcg/mL, and the nurse evaluates this level to be:
below the therapeutic level.
at a therapeutic level.
above the therapeutic level.
at a toxic level.
above the therapeutic level.
Although the optimal level may vary from patient to patient, most standard references have suggested that the therapeutic range for theophylline blood level is 10 to 20 mcg/mL. However, most clinicians now advise levels between 5 and 15 mcg/mL.
A patient with end-stage renal failure has been admitted to the hospital for severe anemia. She is refusing blood transfusions. The nurse anticipates drug therapy with which drug to stimulate the production of red blood cells
Folic acid
Cyanocobalamin (vitamin B12)
Epoetin alfa (Epogen)
Filgrastim (Neupogen)
Epoetin alfa (Epogen)
Epoetin alfa is a colony-stimulating factor that is responsible for erythropoiesis, or formation of red blood cells. The other options are incorrect.
A patient tells the nurse that she wants to start taking the herbal product goldenseal to improve her health. The nurse will assess for which potential cautions or contraindications to goldenseal (Select all that apply.)
Taking a proton-pump inhibitor Nasal congestion Hypothyroidism Hypertension Sinus infections Pregnancy
Taking a proton-pump inhibitor
Hypertension
Pregnancy
Goldenseal is contraindicated in patients with acute or chronic gastrointestinal disorders and during pregnancy (because it has uterine stimulant properties). It should be used with caution by those with cardiovascular disorders. Potential drug interactions may occur with gastric acid suppressors such as antacids, histamine H2 blockers (e.g., ranitidine), and proton pump inhibitors (e.g., omeprazole), theoretically because of their reduced effectiveness resulting from the acid-promoting effect of the herb, and with antihypertensive drugs (because of the vasoconstrictive activity of the herb). Goldenseal is potentially useful for sinus infections and chronic nasal allergies.
When educating a patient recently placed on inhaled corticosteroids, the nurse will discuss which potential adverse effects
Fatigue and depression
Anxiety and palpitations
Headache and rapid heart rate
Oral candidiasis and dry mouth
Oral candidiasis and dry mouth
Oral candidiasis and dry mouth are two possible adverse effects of inhaled corticosteroids. The other responses are incorrect.
The nurse is teaching a patient with iron-deficiency anemia about foods to increase iron intake. Which food may enhance the absorption of oral iron forms
Milk Yogurt Antacids Orange juice .
Orange juice
Orange juice contains ascorbic acid, which enhances the absorption of oral iron forms; antacids, milk, and yogurt may interfere with absorption
A patient has received an overdose of intravenous heparin, and is showing signs of excessive bleeding. Which substance is the antidote for heparin overdose
Vitamin E
Vitamin K
Protamine sulfate
Potassium chloride
Protamine sulfate
Protamine sulfate is a specific heparin antidote and forms a complex with heparin, completely reversing its anticoagulant properties. Vitamin K is the antidote for warfarin (Coumadin) overdose. The other options are incorrect.
A patient has been taking an AED for several years as part of his treatment for partial seizures. His wife has called because he ran out of medication this morning and wonders if he can go without it for a week until she has a chance to go to the drugstore. What is the nurse’s best response
“He is taking another antiepileptic drug, so he can go without the medication for a week.”
“Stopping this medication abruptly may cause withdrawal seizures. A refill is needed right away.”
“He can temporarily increase the dosage of his other antiseizure medications until you get the refill.”
“He can stop all medications because he has been treated for several years now.”
Stopping this medication abruptly may cause withdrawal seizures. A refill is needed right away.”
Abrupt discontinuation of antiepileptic drugs can lead to withdrawal seizures. The other options are incorrect. The nurse cannot change the dose or stop the medication without a prescriber’s order.
A patient has been taking phenobarbital for 2 weeks as part of his therapy for epilepsy. He tells the nurse that he feels tense and that “the least little thing” bothers him now. Which is the correct explanation for this problem
These are adverse effects that usually subside after a few weeks.
The drug must be stopped immediately because of possible adverse effects.
This drug causes the rapid eye movement (REM) sleep period to increase, resulting in nightmares and restlessness.
This drug causes deprivation of REM sleep and may cause the inability to deal with normal stress.
This drug causes deprivation of REM sleep and may cause the inability to deal with normal stress.
Barbiturates such as phenobarbital deprive people of REM sleep, which can result in agitation and the inability to deal with normal stress. A rebound phenomenon occurs when the drug is stopped (not during therapy), and the proportion of REM sleep increases, sometimes resulting in nightmares. The other options are incorrect.
The nurse has given medication instructions to a patient receiving phenytoin (Dilantin). Which statement by the patient indicates that the patient has an adequate understanding of the instructions
“I will need to take extra care of my teeth and gums while on this medication.”
“I can go out for a beer while on this medication.”
“I can skip doses if the side effects bother me.”
“I will be able to stop taking this drug once the seizures stop.”
“I will need to take extra care of my teeth and gums while on this medication.”
Scrupulous dental care is necessary to prevent gingival hypertrophy during therapy with phenytoin. Alcohol and other central nervous system depressants may cause severe sedation. Consistent dosing is important to maintain therapeutic drug levels. Therapy with AEDs usually must continue for life and must not be stopped once seizures stop.
A patient is taking intravenous aminophylline for a severe exacerbation of chronic obstructive pulmonary disease. The nurse will assess for which therapeutic response
Increased sputum production
Increased heart rate
Increased respiratory rate
Increased ease of breathing
Increased ease of breathing
The therapeutic effects of bronchodilating drugs such as xanthine derivatives include increased ease of breathing. The other responses are incorrect.
The nurse notes in a patient’s medication history that the patient is taking allopurinol (Zyloprim). Based on this finding, the nurse interprets that the patient has which disorder
Rheumatoid arthritis
Gout
Osteoarthritis
Systemic lupus erythematosus
Gout
Allopurinol is indicated for the treatment of gout but is not indicated for the other disorders listed.
A patient has a 9-year history of a seizure disorder that has been managed well with oral phenytoin (Dilantin) therapy. He is to be NPO (consume nothing by mouth) for surgery in the morning. What will the nurse do about his morning dose of phenytoin
Give the same dose intravenously.
Give the morning dose with a small sip of water.
Contact the prescriber for another dosage form of the medication.
Notify the operating room that the medication has been withheld.
Contact the prescriber for another dosage form of the medication.
If there are any questions about the medication order or the medication prescribed, contact the prescriber immediately for clarification and for an order of the appropriate dose form of the medication. Do not change the route without the prescriber’s order. There is an increased risk of seizure activity if one or more doses of the AED are missed.
A patient has experienced insomnia for months, and the physician has prescribed a medication to help with this problem. The nurse expects which drug to be used for long-term treatment of insomnia
Secobarbital (Seconal), a barbiturate
Diazepam (Valium), a benzodiazepine
Midazolam (Versed), a benzodiazepine
Eszopiclone (Lunesta), a nonbenzodiazepine sleep aid
Eszopiclone (Lunesta), a nonbenzodiazepine sleep aid
Eszopiclone (Lunesta) is one of the newest prescription hypnotics to be approved for long-term use in treatment of insomnia. Barbiturates and benzodiazepines are not appropriate for long-term treatment of insomnia; midazolam is used for procedural (moderate) sedation.
When giving dextromethorphan, the nurse understands that this drug suppresses the cough reflex by which mechanism of action
Causing depression of the central nervous system
Anesthetizing the stretch receptors
Having direct action on the cough center
Decreasing the viscosity of the bronchial secretions
Having direct action on the cough center
Dextromethorphan suppresses the cough reflex through a direct action on the cough center. The other options are incorrect.
The nurse notes in the patient’s medication orders that the patient will be starting anticoagulant therapy. What is the primary goal of anticoagulant therapy
Stabilizing an existing thrombus
Dissolving an existing thrombus
Preventing thrombus formation
Dilating the vessel around a clot
Preventing thrombus formation
Anticoagulants prevent thrombus formation but do not dissolve or stabilize an existing thrombus, nor do they dilate vessels around a clot.
A patient taking entacapone (Comtan) for the first time calls the clinic to report a dark discoloration of his urine. After listening to the patient, the nurse realizes that what is happening in this situation
This is a harmless effect of the drug
.
The patient has taken this drug along with red wine or cheese.
The patient is having an allergic reaction to the drug.
The ordered dose is too high for this patient.
This is a harmless effect of the drug
.
COMT inhibitors, including entacapone, may darken a patient’s urine and sweat.
The nurse is reviewing new medication orders for a patient who has an epidural catheter for pain relief. One of the orders is for enoxaparin (Lovenox), a low–molecular-weight heparin (LMWH). What is the nurse’s priority action
Give the LMWH as ordered.
Double-check the LMWH order with another nurse, and then administer as ordered.
Stop the epidural pain medication, and then administer the LMWH.
Contact the prescriber because the LMWH cannot be given if the patient has an epidural catheter.
Contact the prescriber because the LMWH cannot be given if the patient has an epidural catheter
LMWHs are contraindicated in patients with an indwelling epidural catheter; they can be given 2 hours after the epidural is removed. This is very important to remember, because giving an LMWH with an epidural has been associated with epidural hematoma.
The nurse is reviewing herbal therapies. Which is a common use of the herb feverfew
Muscle aches
Migraine headaches
Leg cramps
Incision pain after surgery
Migraine headaches
Feverfew is commonly used for migraine headaches, menstrual problems, arthritis, and fever. Possible adverse effects include muscle stiffness and muscle and joint pain.
While monitoring a depressed patient who has just started SSRI antidepressant therapy, the nurse will observe for which problem during the early time frame of this therapy
Hypertensive crisis
Self-injury or suicidal tendencies
Extrapyramidal symptoms
Loss of appetite
Self-injury or suicidal tendencies
In 2005, the U.S. Food and Drug Administration (FDA) issued special black-box warnings regarding the use of all classes of antidepressants in both adult and pediatric patient populations. Data from the FDA indicated a higher risk for suicide in patients receiving these medications. As a result, current recommendations for all patients receiving antidepressants include regular monitoring for signs of worsening depressive symptoms, especially when the medication is started or the dosage is changed. The other options are incorrect.
A patient was diagnosed with pancreatic cancer last month, and has complained of a dull ache in the abdomen for the past 4 months. This pain has been gradually increasing, and the pain relievers taken at home are no longer effective. What type of pain is the patient experiencing
Acute pain
Chronic pain
Somatic pain
Neuropathic pain
Chronic pain
Chronic pain is associated with cancer and is characterized by slow onset, long duration, and dull, persistent aching. The patient’s symptoms are not characteristics of acute pain, somatic pain, or neuropathic pain.
A patient is taking flurazepam (Dalmane) three to four nights a week for sleeplessness. She is concerned that she cannot get to sleep without taking the medication. What nonpharmacologic measures should the nurse suggest to promote sleep for this patient
Providing a quiet environment
Exercising before bedtime to become tired
Consuming heavy meals in the evening to promote sleepiness
Drinking hot tea or coffee just before bedtime
Providing a quiet environment
Nonpharmacologic approaches to induce sleep include providing a quiet environment, avoiding heavy exercise before bedtime, avoiding heavy meals late in the evening, and drinking warm decaffeinated drinks, such as warm milk, before bedtime.
A 38-year-old male patient stopped smoking 6 months ago. He tells the nurse that he still feels strong cigarette cravings and wonders if he is ever going to feel “normal” again. Which statement by the nurse is correct
“It’s possible that these cravings will never stop.”
“These cravings may persist for several months.”
“The cravings tell us that you are still using nicotine.”
“The cravings show that you are about to experience nicotine withdrawal.”
These cravings may persist for several months.”
Cigarette cravings may persist for months after nicotine withdrawal. The other statements are false.

Drowsiness, headache, weight loss
Dizziness, insomnia, nausea
Peripheral edema, fatigue, syncope
Heart palpitations, hypotension, urinary retention
Heart palpitations, hypotension, urinary retention
Common adverse reactions associated with carbidopa-levodopa include palpitations, hypotension, urinary retention, dyskinesia, and depression. The other effects may occur with other antiparkinson drugs.
