1. A client is starting a new prescription for verapamil. Which of the following instructions should be included?

• A. Take the medication with a full glass of water.
• B. Avoid grapefruit juice.
• C. Monitor blood pressure regularly.
• D. Monitor heart rate daily.

Correct answer: B

Rationale: Clients prescribed verapamil should be advised to avoid grapefruit juice as it can potentiate the drug's effects, leading to adverse reactions. Grapefruit juice can inhibit the metabolism of verapamil, resulting in higher blood levels of the medication and an increased risk of side effects. Instructions such as taking the medication with a full glass of water (Choice A) are not specific to verapamil and are generally recommended. While monitoring blood pressure regularly (Choice C) is important for clients on antihypertensive medications, it is not a direct concern related to verapamil. Monitoring heart rate daily (Choice D) is not a primary consideration when starting verapamil, as it is more commonly used for its effects on blood pressure and arrhythmias rather than heart rate.

2. A client has been on levothyroxine therapy for several months. Which of the following findings indicates a therapeutic response to the medication?

• A. Decrease in level of thyroxine (T4)
• B. Increase in weight
• C. Increase in hours of sleep per night
• D. Decrease in level of thyroid stimulating hormone (TSH)

Correct answer: D

Rationale: A therapeutic response to levothyroxine is indicated by a decrease in the level of TSH. This decrease signifies that the body requires less stimulation to produce thyroid hormone, reflecting a normalization of thyroid function due to the medication's effectiveness. Choices A, B, and C are incorrect as an increase in T4 levels, weight gain, and increased sleep hours are not indicative of a therapeutic response to levothyroxine therapy.

3. What is the primary action of warfarin as an anticoagulant?

• A. Prevents the formation of blood clots
• B. Dissolves existing blood clots
• C. Dilates coronary arteries
• D. Treats rhythm disturbances

Correct answer: A

Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.

4. Which of the following is not related to drug toxicity of Atenolol?

• A. CHF
• B. Tachycardia
• C. AV block
• D. Sedative appearance

Correct answer: B

Rationale: Atenolol, a beta-blocker, is not typically associated with tachycardia. Instead, drug toxicity of Atenolol is more commonly linked to bradycardia due to its beta-blocking effects on the heart's electrical conduction system. Symptoms of Atenolol toxicity may include heart failure (CHF), AV block, and a sedative appearance, but not tachycardia.

5. A client has a new prescription for Levothyroxine to treat hypothyroidism. Which of the following instructions should be included in the teaching?

• A. Take this medication with food.
• B. Take this medication at bedtime.
• C. Expect to see results in 1 week.
• D. Do not discontinue the medication without consulting the provider.

Correct answer: D

Rationale: The correct instruction for a client with a new prescription for Levothyroxine to treat hypothyroidism is not to discontinue the medication without consulting the provider. Abrupt cessation could lead to the return of hypothyroid symptoms, emphasizing the importance of medical guidance when considering any changes to the treatment plan. Choice A is incorrect because Levothyroxine should be taken on an empty stomach, typically in the morning. Choice B is incorrect as it contradicts the timing of administration for Levothyroxine. Choice C is inaccurate as it usually takes a few weeks for the full effects of Levothyroxine to be seen, not just 1 week.
