Correct Answer: D

Rationale: When a postoperative client's respiratory rate increases, it is essential to determine the underlying cause. Pain, anxiety, and fluid accumulation in the lungs can lead to tachypnea (increased respiratory rate). Therefore, the priority intervention is to assess if pain is the contributing factor. Encouraging increased ambulation may worsen oxygen desaturation in a client with a rising respiratory rate. Offering a high-carbohydrate snack is not indicated as it can increase carbon metabolism; instead, consider providing an alternative energy source like Pulmocare liquid supplement. Forcing fluids may exacerbate respiratory congestion in a client with a compromised cardiopulmonary system, potentially leading to fluid overload. Therefore, determining the role of pain in tachypnea is crucial for appropriate management.

Correct Answer: D

Rationale: The nurse's initial step should be to assess the client's adherence to the original instructions. By asking the client to describe the routine they are following, the nurse gains more specific information than relying solely on a sleep diary. This information will help the nurse identify any deviations or areas needing adjustment in the technique. Encouraging the client to persist with an unsuccessful routine without evaluation is not beneficial. Adding regular exercise, although important for overall sleep health, should come after ensuring the correct execution of the relaxation technique.

Correct Answer: A

Rationale: Performing range-of-motion exercises is beneficial in reducing contractures around joints, maintaining joint mobility, and preventing stiffness in immobile clients. This intervention helps preserve muscle strength and joint function. Options B, C, and D are incorrect because: Option B suggesting decreasing fluid intake to prevent diarrhea is not relevant to preventing complications of immobility and could lead to dehydration; Option C, massaging the client's legs to reduce embolism occurrence, is not a recommended practice as massage can dislodge blood clots and increase the risk of embolism; Option D, turning the client from side to back every shift, is not sufficient as it does not address the need for maintaining joint mobility and preventing contractures in immobile clients.

Correct Answer: B

Rationale: When a nurse is assigned to care for a close friend, it is essential to maintain professional boundaries to ensure the best care for the client and the nurse. The most appropriate action for the nurse to take first is to explain the relationship to the charge nurse and ask for reassignment (B). This is important to avoid potential conflicts of interest and maintain objectivity in the care provided. Option A, notifying the friend about confidentiality, may not address the underlying issue of the conflict of interest. Option C, asking the client if the assignment is uncomfortable, may not be appropriate as it puts the client in a difficult position. Option D, accepting the assignment but protecting the client's confidentiality, does not address the conflict of interest and potential ethical issues that may arise from caring for a close friend.

Correct Answer: A

Rationale: Implementing suicide precautions is the most critical intervention in this scenario as it directly addresses the patient's safety and the prevention of self-harm. The patient's significant weight loss, chronic low self-esteem, suicide plan, and recent initiation of an antidepressant medication indicate a high risk of self-harm. Suicide precautions involve close monitoring, removing harmful objects, and ensuring a safe environment to prevent the patient from acting on suicidal thoughts. While offering high-calorie snacks and fluids, assisting the patient in identifying personal strengths, and observing for therapeutic effects of the antidepressant are important aspects of care, they do not directly address the immediate risk of self-harm that implementing suicide precautions does.
