A client with tuberculosis is prescribed rifampin. What side effect should the nurse inform the client about?

Correct Answer: B

Rationale: The correct answer is B. Rifampin can cause red-orange discoloration of bodily fluids, including urine, saliva, and tears. This is a harmless side effect, but clients should be informed beforehand to prevent alarm. Choice A is incorrect as orange-colored urine is not a sign of kidney dysfunction related to rifampin. Choice C is incorrect because rifampin is more commonly associated with liver toxicity rather than kidney dysfunction. Choice D is incorrect as vision changes are not a typical side effect of rifampin.

Correct Answer: B

Rationale: The correct teaching for a client prescribed warfarin is to report any signs of bleeding, such as unusual bruising, nosebleeds, or blood in the urine or stool. Warfarin is an anticoagulant that increases the risk of bleeding, so it is crucial for the client to promptly report any bleeding-related symptoms for evaluation by a healthcare provider. Choices A, C, and D are incorrect. Avoiding foods high in vitamin K, such as spinach, is more relevant for clients taking warfarin to maintain consistent vitamin K intake. Warfarin should be taken with food to avoid gastrointestinal upset, so taking it on an empty stomach is not recommended. Monitoring for changes in blood pressure is not directly related to warfarin therapy; instead, the focus should be on monitoring for signs of bleeding.

Correct Answer: D

Rationale: The correct answer is D: Take iron supplements with vitamin C to improve absorption. Vitamin C enhances iron uptake, making it more bioavailable for the body. It is essential to avoid taking iron supplements with milk (choice B) as calcium-rich foods can hinder iron absorption. Taking iron supplements with meals (choice A) can help reduce stomach upset, but the optimal way to enhance absorption is with vitamin C. Black, tarry stools (choice C) are not a typical side effect of iron supplements and should be reported to the healthcare provider.

Correct Answer: C

Rationale: The correct intervention for a client with Crohn's disease reporting diarrhea is to encourage a high-fiber diet and regular physical activity. A high-fiber diet helps manage diarrhea in Crohn's disease by adding bulk to the stool and promoting more regular bowel movements. Instructing the client to drink clear fluids and avoid solid foods (Choice A) may not be appropriate as it can further exacerbate diarrhea. Administering antidiarrheal medication (Choice B) without addressing the underlying cause may not be the best initial approach. Encouraging a high-fiber diet and physical activity (Choice C) is beneficial for managing symptoms. Restricting fluid intake and monitoring electrolytes (Choice D) is not recommended as it can lead to dehydration, which is a concern in clients with diarrhea.

Correct Answer: B

Rationale: The correct answer is B. Levothyroxine should be taken at the same time every day to maintain stable thyroid hormone levels and ensure effective management of hypothyroidism. Consistent dosing is critical for preventing fluctuations in hormone levels. Choice A is incorrect because levothyroxine is usually recommended to be taken on an empty stomach for optimal absorption. Choice C is incorrect because increased sensitivity to cold is not a common side effect of levothyroxine. Choice D is incorrect because adjusting the dosage without healthcare provider guidance can be dangerous and should not be done independently.
