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

Correct Answer: B

Rationale: Increasing fluid intake is essential when taking allopurinol to prevent the formation of kidney stones. Allopurinol can increase the levels of uric acid in the body, which can lead to kidney stone formation. By increasing fluid intake, the client can help flush out excess uric acid and prevent the development of kidney stones. It is important to drink plenty of water throughout the day to maintain adequate hydration and reduce the risk of kidney stone formation. Choices A, C, and D are incorrect. Taking allopurinol with food or in the morning does not specifically relate to preventing kidney stone formation. Avoiding dairy products is not a standard recommendation when taking allopurinol.

Correct Answer: B

Rationale: The correct answer is to instruct the client to avoid drinking alcohol. Isoniazid can cause liver damage, and alcohol consumption can increase this risk. Therefore, it is crucial to avoid alcohol while taking isoniazid to prevent potential liver complications. Choice A is incorrect because isoniazid is typically taken with food to reduce gastrointestinal upset. Choice C is incorrect because antacids can decrease the absorption of isoniazid. Choice D is incorrect as there is no specific recommendation to increase leafy green vegetable intake when taking isoniazid.

Correct Answer: C

Rationale: The correct answer is C: Heat intolerance. Heat intolerance is a sign of levothyroxine toxicity and requires immediate attention. Weight loss may actually be an expected outcome of levothyroxine therapy as it can help regulate metabolism in hypothyroidism. Insomnia can occur as a side effect of levothyroxine but is not as concerning as heat intolerance. Dry skin is a common symptom of hypothyroidism and may improve with levothyroxine therapy, so it is not a priority finding to report to the provider.

Correct Answer: B

Rationale: The correct answer is to instruct the client to monitor their heart rate daily when taking atenolol. Atenolol can lead to bradycardia, a slow heart rate. By monitoring heart rate daily, the client can promptly identify any significant changes and seek medical attention if necessary. This proactive approach enables early detection of potential adverse effects of atenolol, contributing to the client's safety and well-being. Choices A, C, and D are incorrect because taking atenolol at bedtime, increasing potassium-rich foods intake, or avoiding dairy products are not specific instructions related to the potential side effects of atenolol.

Correct Answer: C

Rationale: Increasing folic acid intake is crucial when taking methotrexate because the medication can lead to folic acid deficiency. Folic acid supplementation helps counteract this deficiency and reduces the risk of adverse effects associated with methotrexate therapy. Choices A, B, and D are incorrect. Avoiding dairy products is not specifically necessary for methotrexate therapy. Methotrexate is usually taken with food to reduce gastrointestinal side effects, so taking it on an empty stomach is not recommended. Monitoring for signs of hyperglycemia is not directly related to methotrexate use.
