Correct Answer: A

Rationale: The correct answer is A: Drinking grapefruit juice. Grapefruit juice can increase the risk of statin toxicity by interfering with the enzyme that metabolizes statin medications, leading to higher drug levels in the body. This interaction can potentially cause adverse effects. Therefore, patients should be advised to avoid consuming grapefruit juice while taking statins. Choices B, C, and D are incorrect. Consuming high-protein meals, exercising regularly, and taking the medication in the morning are not contraindicated while on statin therapy. In fact, following a healthy diet, engaging in physical activity, and taking the medication at a consistent time each day can be beneficial for patients prescribed statins.

Correct Answer: A

Rationale: The correct answer is A: Decreased deep tendon reflexes. Magnesium sulfate toxicity can lead to diminished deep tendon reflexes, respiratory depression, and decreased urine output. Diminished deep tendon reflexes are an early sign of magnesium toxicity and indicate the need to discontinue the infusion. Elevated blood pressure (choice B) is not typically associated with magnesium toxicity. Increased urinary output (choice C) is also not a common finding in magnesium toxicity. Hyperreflexia (choice D) is not consistent with the expected findings of magnesium toxicity, which typically causes decreased reflexes.

Correct Answer: B

Rationale: The correct instruction the nurse should provide to a client prescribed ferrous sulfate is to take it with fluids other than coffee or tea. Coffee and tea can inhibit iron absorption. Therefore, choices A, C, and D are incorrect. Avoiding strawberries, citrus fruits, and melon is not necessary for improving absorption of ferrous sulfate, taking it on a full stomach is not recommended, and doubling the dose if a dose is missed can lead to an overdose.

Correct Answer: B

Rationale: The correct answer is to instruct the client to reduce potassium intake. Clients with chronic kidney disease should limit potassium intake to prevent hyperkalemia, as the kidneys may struggle to remove excess potassium. Increasing protein intake between dialysis sessions (Choice A) is not recommended as it can increase urea production, adding to the workload of the kidneys. Avoiding iron supplements (Choice C) is not necessary unless iron levels are high. Expecting weight gain after each dialysis session (Choice D) is incorrect as patients typically experience weight loss due to fluid removal during dialysis.

Correct Answer: C

Rationale: The psychomotor domain involves physical activity and motor skills, such as ambulation, making it the correct domain for this goal. Choices A, B, and D are incorrect: Affective domain focuses on emotions and attitudes, physical domain is not a recognized domain in Bloom's taxonomy, and cognitive domain pertains to knowledge and intellectual skills, none of which directly relate to the physical act of ambulation.
