Correct Answer: A

Rationale: The client has a plan to read until feeling sleepy, indicating an intention to sleep. Therefore, offering a PRN sedative-hypnotic (C) is unnecessary, especially since it is a stronger sleep aid. Option (D) is not needed as the client already has a plan to address his sleeplessness. Assessing the surgical dressing (B) is not relevant to the client's immediate need for sleep. Leaving the room and closing the door (A) is the appropriate action to provide a conducive environment for the client to rest.

Correct Answer: B

Rationale: The best response for the nurse is to inform the client that gradual tapering must be used to discontinue the medication. Abrupt cessation of antidepressants can lead to withdrawal symptoms or a recurrence of depressive symptoms. Choice A is not the best response as it does not address the need for a proper discontinuation plan. Choice C is not the best response as it focuses solely on the side effects and does not address the discontinuation process. Choice D is not the best response because while side effects may diminish over time, the focus here should be on the safe discontinuation of the medication to prevent adverse effects.

Correct Answer: B

Rationale: The correct answer is B because the absence of patellar and triceps reflexes indicates potential magnesium toxicity, requiring immediate intervention. Nausea and lethargy are common side effects of elevated magnesium levels and should be reported, but they are not as critical as the loss of deep tendon reflexes. Decreased breath sounds suggest the need for coughing and deep breathing to prevent atelectasis, which is important but not as urgent as addressing magnesium toxicity.

Correct Answer: A

Rationale: The correct answer is A. The patient should be placed near the nurse's station if confused to allow close monitoring by the staff. To help improve serum sodium levels, water intake is restricted, so a patient with hyponatremia should not be placed near a water fountain. Peaked T waves are a sign of hyperkalemia, not hyponatremia, so telemetry for this purpose is unnecessary. Placing a confused patient in a semi-private room could be disruptive to the other patient. Additionally, the patient needs sodium replacement, not a low-salt diet.

Correct Answer: A

Rationale: The correct answer is A: Daily alcohol intake. Hypomagnesemia is often associated with alcoholism, making it crucial for the nurse to assess the patient's alcohol consumption. Protein intake is not directly related to magnesium levels. The use of over-the-counter laxatives and multivitamin/mineral supplements would typically increase magnesium levels, which are not the focus when dealing with hypomagnesemia.
