1. A client has a new prescription for Labetalol. Which of the following instructions should the nurse include?

A. Take this medication at bedtime.
B. Avoid sudden discontinuation of the medication.
C. Increase your intake of sodium-rich foods.
D. Avoid drinking grapefruit juice.

Correct answer: B

Rationale: The correct instruction for a client on Labetalol is to avoid sudden discontinuation of the medication. Labetalol is a beta-blocker that, if abruptly stopped, can lead to rebound hypertension and other cardiac issues. It is essential for patients to taper off this medication under medical supervision to prevent adverse effects.

2. A client has a new prescription for Clopidogrel. Which of the following instructions should the nurse include?

A. Monitor for signs of bleeding.
B. Avoid taking the medication with food.
C. Expect to have increased urination.
D. Take the medication with an antacid.

Correct answer: A

Rationale: Corrected Rationale: Clopidogrel is an antiplatelet medication that increases the risk of bleeding. The client should monitor for any signs of bleeding, such as easy bruising, prolonged bleeding from cuts, blood in urine or stool, and report them promptly to their healthcare provider for further evaluation and management. Choice B is incorrect because Clopidogrel can be taken with or without food. Choice C is incorrect as increased urination is not a common side effect of Clopidogrel. Choice D is incorrect as taking Clopidogrel with an antacid may reduce its effectiveness.

3. What is the pharmacological action of metformin?

A. Blocks stimulation of beta1 and beta2.
B. Blocks vasoconstriction and aldosterone.
C. Acts at many levels in the CNS to produce an anxiolytic effect.
D. Decreases hepatic glucose production.

Correct answer: D

Rationale: The correct answer is D: Decreases hepatic glucose production. Metformin's primary pharmacological action is to decrease hepatic glucose production, leading to lower blood sugar levels and improved insulin sensitivity in the liver. Choices A, B, and C are incorrect because metformin does not block stimulation of beta1 and beta2 receptors, vasoconstriction, aldosterone, or act in the CNS to produce an anxiolytic effect. Therefore, these options are not reflective of metformin's mechanism of action.

4. A healthcare professional is teaching a client who has a new prescription for Clopidogrel. Which of the following laboratory values should the healthcare professional monitor to assess for potential adverse effects?

A. White blood cell count
B. Platelet count
C. Hemoglobin
D. Blood glucose

Correct answer: B

Rationale: Clopidogrel is an antiplatelet medication that works by preventing blood clots. Monitoring the patient's platelet count is essential because a decrease in platelet count can increase the risk of bleeding. By assessing the platelet count, the healthcare professional can detect any potential adverse effects related to the medication and take appropriate actions to prevent complications. White blood cell count, hemoglobin, and blood glucose levels are not directly affected by Clopidogrel, so they are not the primary values to monitor for potential adverse effects of this medication.

5. A drug ending in the suffix (navir) is considered a ______.

A. Antidepressant
B. Protease inhibitor
C. Beta antagonist
D. H antagonist

Correct answer: B

Rationale: When a drug name ends in the suffix -navir, it indicates that the drug is a protease inhibitor. Protease inhibitors are commonly used in antiviral therapy to treat infections by inhibiting viral replication. Therefore, the correct answer is B: Protease inhibitor.
