ATI Proctored Pharmacology Test

1. A client has a new prescription for Efavirenz, an NNRTI. Which of the following instructions should the nurse include?

A. Take this medication at bedtime to prevent drowsiness.
B. Take this medication with a glass of milk.
C. Take this medication with a glass of juice.
D. Take this medication at the same time every day.

Correct answer: A

Rationale: The correct instruction is to take Efavirenz at bedtime to prevent drowsiness and manage central nervous system side effects like dizziness and vivid dreams. While it is important to take the medication at the same time daily for consistent blood levels, the emphasis should be on bedtime to minimize the impact of these side effects. Choices B and C suggesting taking the medication with milk or juice are incorrect and not relevant to optimizing Efavirenz therapy.

2. When preparing to administer IV Acyclovir for Herpes Zoster, what action should the nurse take?

A. Infuse the medication over 1 hour.
B. Monitor the client's blood pressure every 15 minutes during infusion.
C. Administer a stool softener.
D. Monitor the client's blood glucose level every 4 hours during infusion.

Correct answer: A

Rationale: The correct action for the nurse is to infuse IV Acyclovir over at least 1 hour to prevent nephrotoxicity. Rapid infusion can lead to adverse effects, so a slow infusion rate is crucial for patient safety. Monitoring blood pressure, administering a stool softener, or monitoring blood glucose levels are not directly related to the administration of IV Acyclovir for Herpes Zoster.

3. What is the correct definition of drug absorption?

A. Movement of a drug from the site of administration to various tissues of the body
B. Describes the absorption, distribution, metabolism, and excretion of drugs
C. These types of drugs can be taken over the counter
D. This addresses how various drugs affect different forms of the body

Correct answer: A

Rationale: The correct definition of drug absorption is the movement of a drug from the site of administration into various tissues of the body. It is the process by which a drug is taken up and enters the systemic circulation. Choice B describes the pharmacokinetics of drugs, including absorption, distribution, metabolism, and excretion, but it is not a specific definition of drug absorption. Choice C is unrelated to drug absorption, as it refers to over-the-counter drugs. Choice D is too vague and does not specifically address the process of drug absorption.

4. A client has a new prescription for Atenolol. Which of the following instructions should the nurse provide?

A. Take this medication with grapefruit juice.
B. Monitor your blood pressure and heart rate regularly.
C. You may experience a rapid heart rate.
D. Increase your intake of potassium-rich foods.

Correct answer: B

Rationale: The correct answer is B: 'Monitor your blood pressure and heart rate regularly.' Atenolol is a beta-blocker used to treat hypertension and other cardiovascular conditions. Patients should monitor their blood pressure and heart rate regularly to assess the medication's effectiveness and check for adverse effects like bradycardia or hypotension. Choice A is incorrect because Atenolol should not be taken with grapefruit juice, which can interfere with its absorption. Choice C is incorrect because Atenolol typically causes a decrease in heart rate, not a rapid heart rate. Choice D is incorrect because there is no specific need to increase potassium-rich foods while taking Atenolol.

5. What are the Therapeutic Effects of Lithium?

A. Prevents or decreases the incidence of acute manic episodes
B. Maintenance of blood glucose
C. Control of hyperglycemia in diabetic patients
D. Diminished seizure activity

Correct answer: A

Rationale: The therapeutic effect of lithium is that it prevents or decreases the incidence of acute manic episodes in patients with bipolar disorder. Lithium is commonly used as a mood stabilizer in the treatment of bipolar disorder due to its ability to reduce the frequency and severity of manic episodes. Choices B, C, and D are incorrect as lithium is not used for the maintenance of blood glucose, control of hyperglycemia in diabetic patients, or to diminish seizure activity. These effects are not associated with the use of lithium as a medication.
