Correct Answer: A

Rationale: The correct instruction for the nurse to include is to advise the client to avoid using deodorant until the incision heals. Using deodorant can lead to skin irritation, which should be prevented following a mastectomy. Choice B is incorrect because performing arm exercises should typically be delayed until recommended by the healthcare provider to prevent strain on the surgical site. Choice C is incorrect as tight-fitting clothing can increase discomfort and hinder proper healing. Choice D is also incorrect because initiating arm exercises should be based on the healthcare provider's guidance and not a specific timeframe.

Correct Answer: B

Rationale: The correct answer is B: 'Sleep with the head of your bed elevated.' Elevating the head of the bed helps reduce acid reflux by keeping the head higher than the stomach, preventing stomach acid from flowing back into the esophagus. Choices A, C, and D are incorrect. Avoiding eating small, frequent meals, lying down after eating, and drinking fluids with meals can exacerbate GERD symptoms by increasing stomach acid production and promoting acid reflux.

Correct Answer: B

Rationale: Administering lorazepam is the appropriate intervention for a client experiencing acute alcohol withdrawal. Lorazepam helps reduce agitation and prevent complications during this withdrawal phase. Choice A, providing a low-sodium diet, is not directly related to managing alcohol withdrawal symptoms. Choice C, keeping the client in a supine position, is not necessary and may not address the client's withdrawal symptoms. Choice D, placing the client in restraints, should only be considered if the client is at risk of harming themselves or others, but it is not the primary intervention for managing alcohol withdrawal.

Correct Answer: C

Rationale: A sodium level of 125 mEq/L indicates hyponatremia, which can lead to hypotension. Hyponatremia is associated with signs such as confusion and weakness, rather than increased appetite, dry mucous membranes, or hyperreflexia. Therefore, the nurse should expect hypotension as a finding in a client with a sodium level of 125 mEq/L.

Correct Answer: D

Rationale: The correct answer is D: 'Serosanguineous wound drainage.' Serosanguineous drainage should be reported in postoperative clients as it may indicate complications such as infection or impaired wound healing. Options A, B, and C are expected findings in a postoperative client. Bowel sounds present in all four quadrants indicate normal gastrointestinal function, a temperature of 37.5°C (99.5°F) is within the normal range, and scant urine output may be expected initially due to factors like anesthesia and fluid shifts postoperatively.
