1. Before administering lithium to a client with bipolar disorder who has been taking the medication for 1 year, the nurse should check to see that which of the following tests has been completed?

Correct answer: A

Rationale: The correct answer is to check the thyroid hormone assay. Long-term lithium use can result in thyroid dysfunction, making it crucial to monitor the client's thyroid function regularly to detect any abnormalities early and prevent potential complications. Liver function tests (choice B) are not specifically associated with lithium therapy. Erythrocyte sedimentation rate (choice C) is a nonspecific test for inflammation and not directly related to lithium therapy. Brain natriuretic peptide (choice D) is a test used to diagnose heart failure and is not relevant to monitoring lithium therapy.

2. Which of the following drugs has a therapeutic effect that prevents thromboembolic events?

Correct answer: A

Rationale: The correct answer is Warfarin. Warfarin is an anticoagulant medication that helps prevent thromboembolic events by inhibiting the formation of blood clots. It is commonly used to reduce the risk of strokes or heart attacks in patients at risk for thrombosis.

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

Correct answer: C

Rationale: The correct instruction for a client prescribed Verapamil is to avoid drinking grapefruit juice. Grapefruit juice can inhibit the metabolism of Verapamil, leading to increased blood levels of the medication. This can result in a higher risk of adverse effects, such as hypotension and bradycardia. Therefore, it is essential for the client to avoid grapefruit juice while taking Verapamil to prevent potential complications. Choices A, B, and D are incorrect because taking Verapamil at bedtime, monitoring for signs of hyperglycemia, and increasing potassium-rich foods intake are not specific instructions related to Verapamil therapy and do not address the potential interaction with grapefruit juice.

4. When teaching a client with a new prescription for Timolol how to insert eye drops, which instruction should the nurse include?

Correct answer: C

Rationale: The correct way to administer eye drops is by instructing the client to drop the prescribed amount of medication into the center of the conjunctival sac. This technique helps in proper distribution and absorption of the medication. Choice A is incorrect as pressing the inside corner of the eye is not necessary. Choice B is incorrect because applying eye drops directly on the cornea can cause irritation and discomfort. Choice D is incorrect as wiping the eyes immediately after application can remove the medication and reduce its effectiveness.

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

Correct answer: A

Rationale: The correct instruction the nurse should provide is to rinse the mouth after each use of Beclomethasone. This practice helps reduce the risk of developing oral fungal infections associated with inhaled corticosteroids. Choice B is incorrect because there is no need to limit fluid intake while taking this medication. Choice C is incorrect as there is no specific indication to increase vitamin B12 intake with Beclomethasone. Choice D is incorrect as Beclomethasone should be used according to the prescribed schedule, not as needed.
