1. A client has a prescription for Clonidine to treat hypertension. Which of the following instructions should the nurse include?

A. Discontinue the medication if you experience dry mouth.
B. Take the medication at the same time each day.
C. Double the dose if you miss a dose.
D. Avoid drinking orange juice while taking this medication.

Correct answer: B

Rationale: Correct Answer: Taking Clonidine at the same time each day is crucial to ensure consistent blood levels and effectively manage blood pressure. Consistency in timing helps optimize the medication's effectiveness in controlling hypertension.

2. Which of the following drugs is associated with Stevens-Johnson syndrome?

A. Valproic acid
B. Quinidine
C. Isoniazid
D. Ethosuximide

Correct answer: D

Rationale: Stevens-Johnson syndrome is a severe skin reaction that can be associated with Ethosuximide.

3. When caring for a client prescribed warfarin, which laboratory test should the nurse monitor to evaluate the therapeutic effect of the medication?

A. aPTT
B. Platelet count
C. BUN
D. PT/INR

Correct answer: D

Rationale: The correct laboratory test to monitor the therapeutic effect of warfarin is the PT/INR. Warfarin affects blood clotting, and the PT/INR levels indicate the effectiveness of the medication in preventing clot formation. Therefore, monitoring PT/INR levels helps ensure that the client is within the therapeutic range and is protected from potential complications related to clotting. Choice A (aPTT) is incorrect because while it measures the clotting time, it is not the preferred test for monitoring warfarin therapy. Choice B (Platelet count) is incorrect as it assesses the number of platelets and not the medication's therapeutic effect. Choice C (BUN) is unrelated to monitoring the effects of warfarin therapy and is primarily used to assess kidney function.

4. 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.

5. In which of the following cases is Lansoprazole not used?

A. Gastritis
B. Peptic Ulcers
C. Zollinger-Ellison syndrome
D. Thalamus hypertrophy

Correct answer: D

Rationale: Lansoprazole is a proton pump inhibitor mainly used to treat conditions related to the stomach, such as gastritis, peptic ulcers, and Zollinger-Ellison syndrome. Thalamus hypertrophy is not a condition that Lansoprazole is indicated for; it is used for gastrointestinal issues and not neurological conditions.
