Question 15

The nurse is preparing to administer a medication for sleep. Which intervention applies to the administration of a non-benzodiazepines, such as tartrate (sublinox)

A) these drugs need to be taken about 1 hour before bed time

B) because of their rapid onset, these drugs need to be taken just before bedtime

C) the patient needs to be cautioned about the high incidence of morning drowsiness that may occur after taking these drugs

D) these drugs are less likely to interact with alcohol

Answer 15

The correct answer is:

B) Because of their rapid onset, these drugs need to be taken just before bedtime.

Non-benzodiazepine sleep medications, such as tartrate (Sublinox), are known for their fast-acting properties. They are designed to be taken just before bedtime, as they work quickly to induce sleep. It is important for the nurse to follow the recommended dosing instructions and administer the medication at the appropriate time to ensure its maximum effectiveness in helping the patient fall asleep. This intervention ensures that the medication is timed appropriately to align with the patient’s desired sleep schedule

Question 16

For a patient taking a muscle relaxant the nurse will monitor for which adverse effect?

A) CNS depression

B) hypertension

C) peripheral Edema

D) blurred vision

Answer 16

The correct answer is A) CNS depression.

Muscle relaxants are medications that are commonly used to treat conditions such as muscle spasms, muscle strains, and musculoskeletal injuries. They work by reducing muscle tone and relaxing muscles, which can result in various effects on the central nervous system (CNS).

One of the main adverse effects of muscle relaxants is CNS depression, which refers to a decrease in the functioning of the central nervous system. This can cause symptoms such as drowsiness, sedation, impaired coordination, and slowed reflexes. It is important for nurses to monitor patients taking muscle relaxants for signs of CNS depression, as it can impair their ability to perform activities that require alertness, such as driving or operating machinery, and may increase the risk of falls or accidents.

treatment for migraine headaches. Which condition, if present, may be a contraindication to triptan therapy?
a. Cardiovascular disease
b. Chronic bronchitis
c. History of renal calculi
d. Diabetes mellitus type 2

Answer 24

a. Cardiovascular disease

Cardiovascular disease may be a contraindication to triptan therapy, including sumatriptan succinate (Imitrex), as it can increase the risk of adverse cardiovascular events. Triptans work by constricting blood vessels in the brain, and they can also cause constriction of blood vessels in other parts of the body, including the heart and blood vessels

Question 25

The nurse is reviewing medication therapy with the parents of an adolescent with ADHD. Which statement(s) is/are correct? (Select all that apply.) a. “Be sure to have your child blow his nose before adminis- tering the nasal spray.” b. “This medication is used only when symptoms of ADHD are severe.” c. “The last dose should be taken 4 to 6 hours before bed- time to avoid interference with sleep.” d. “Be sure to contact the physician right away if you notice expression of suicidal thoughts.” e. “We will need to check your child’s height and weight periodically to monitor physical growth.” f. “If adverse effects become severe, stop the medication for 3 to 4 days.”

Answer 25

The correct statements are: a. "Be sure to have your child blow his nose before administering the nasal spray." c. "The last dose should be taken 4 to 6 hours before bedtime to avoid interference with sleep." d. "Be sure to contact the physician right away if you notice expression of suicidal thoughts." e. "We will need to check your child's height and weight periodically to monitor physical growth." Statement b is incorrect, as medication therapy for ADHD is typically used as part of a comprehensive treatment plan and not only for severe symptoms. Medication for ADHD is usually prescribed based on the severity of the symptoms, overall health status of the patient, and other individual factors, as determined by the healthcare provider. Statement f is also incorrect, as stopping medication abruptly without consulting the healthcare provider can result in withdrawal effects or recurrence of symptoms. Any changes to the medication regimen should be discussed with the healthcare provider.

Question 26

A patient with narcolepsy is having problems with excessive daytime sleepiness. The nurse expects which drug to be pre- scribed to improve the patient’s wakefulness? a. phentermine (Ionamin) b. almotriptan (Axert) c. modafinil (Provigil) d. methylphenidate (Ritalin)

Answer 27

a. digoxin (Lanoxin®) Digoxin is a medication used to treat heart failure and certain heart rhythm abnormalities. Carbamazepine (Tegretol) is known to interact with several medications, including digoxin, potentially leading to decreased effectiveness or increased side effects of either medication

Question 28

1. The nurse is preparing to give medications. Which of the following is the most appropriate nursing action for intrave- nous (IV) phenytoin (Dilantin)? a. Give IV doses via rapid IV push. b. Administer in normal saline solutions. c. Administer in dextrose solutions. d. Ensure continuous infusion of drug

Answer 28

b. Administer in normal saline solutions. The most appropriate nursing action for IV phenytoin (Dilantin) is to administer it in normal saline solutions. Phenytoin is not compatible with dextrose solutions, as it can precipitate and become ineffective. Additionally, IV phenytoin should not be given as a rapid IV push, as it can cause cardiovascular adverse effects

Question 29

Which response would the nurse expect to find in a patient with a phenytoin (Dilantin) level of 35 mcg/L? a. Ataxia b. Hypertension c. Seizures d. No unusual response; this level is therapeuti

Answer 29

a. Ataxia Phenytoin (Dilantin) is an antiepileptic medication used to treat and prevent seizures. Therapeutic drug monitoring, including measuring blood levels of phenytoin, is commonly performed to ensure that the medication is within the therapeutic range and to minimize the risk of adverse effects. The therapeutic range for phenytoin levels is typically between 10 to 20 mcg/L for most patients

Question 30

4. A patient is taking pregabalin (Lyrica) but does not have a history of seizures. The nurse recognizes that this drug is also indicated for which of the following? a. Postherpetic neuralgia b. Viral infections c. Parkinson’s disease d. Depression

Answer 31

d. lorazepam (Ativan)

Question 32

8. The nurse is providing education for a patient who will be taking an AED for the first time. Which statement by the patient indicates that further teaching is indicated? a. “I will take the medicine at the same time every day.” b. “I will check with my doctor before taking any over-the- counter drugs.” c. “I will keep the appointments to check my bloodwork.” d. “I can drive to work again once my drug levels are normal.

Answer 32

d. “I can drive to work again once my drug levels are normal." This statement indicates a misunderstanding about the effects of anti-epileptic drugs (AEDs). AEDs are prescribed to control seizures and prevent their recurrence, but they do not necessarily normalize drug levels in the blood. Driving restrictions for patients taking AEDs are usually based on factors such as the type and frequency of seizures, response to treatment, and relevant laws and regulations in the patient's jurisdiction.

Question 33

6. The nurse is administering an AED and will follow which guidelines? (Select all that apply.) a. Monitor the patient for drowsiness. b. Stop medications if seizure activity disappears. c. Give the medication at the same time every day. d. Give the medication on an empty stomach. e. Notify the prescriber if the patient is unable to take the medication

Answer 33

Right a. Monitor the patient for drowsiness. c. Give the medication at the same time every day. e. Notify the prescriber if the patient is unable to take the medication. Wrong b. Stop medications if seizure activity disappears - This statement is not accurate. AEDs should not be stopped abruptly without consulting the healthcare provider, even if seizure activity disappears. Abrupt discontinuation of AEDs can lead to rebound seizures or withdrawal symptoms. d. Give the medication on an empty stomach - This statement is not accurate. Whether AEDs should be given on an empty stomach or with food depends on the specific medication and its instructions. Some AEDs are recommended to be taken with food to minimize potential gastrointestinal side effects, while others may be taken on an empty stomach. The nurse should follow the specific instructions provided by the prescriber or the medication's package insert for proper administration.
