Soaking feet in warm water daily (choice A) may increase the risk of skin breakdown and infection. Wearing shoes one size larger than normal (choice B) can lead to friction and cause blisters.

Correct Answer: B

Rationale: The correct answer is B because spironolactone is a potassium-sparing diuretic, which means it helps the body retain potassium. Instructing the client to avoid foods high in potassium helps prevent hyperkalemia, a potential side effect of spironolactone. Choice A is incorrect because taking spironolactone with a potassium supplement can increase the risk of hyperkalemia. Choice C is not directly related to spironolactone use. Choice D is also incorrect as spironolactone does not need to be taken on an empty stomach.

Correct Answer: B

Rationale: The correct answer is B. Levothyroxine should be taken every morning before breakfast to enhance absorption and maintain consistent thyroid hormone levels. Option A is incorrect because levothyroxine should be taken on an empty stomach. Option C is incorrect because chest pain is not a common side effect of levothyroxine and stopping the medication abruptly can be harmful. Option D is incorrect because taking levothyroxine at bedtime may result in decreased absorption due to interactions with food and other medications.

Correct Answer: B

Rationale: Verifying the client's blood type and Rh factor is crucial before administering blood products to ensure compatibility and prevent adverse reactions.

Option C is incorrect as PRBCs are usually administered through a larger gauge catheter to prevent hemolysis. Option D is incorrect because PRBCs are typically administered with normal saline and not lactated Ringer's solution.
