Correct Answer: A

Rationale: The correct answer is to check oxygen saturation. This is because checking oxygen saturation provides a direct measure of how well the patient is oxygenating post-surgery. It helps healthcare providers assess if the patient is receiving enough oxygen to meet their body's needs. Auscultating lung sounds (choice B) is important to assess respiratory function but may not provide an immediate indication of oxygenation status. Checking for abnormal breath sounds (choice C) is relevant but does not directly assess oxygenation levels. Checking skin color (choice D) can provide some information about oxygenation, but it is not as precise or direct as measuring oxygen saturation.

Correct Answer: C

Rationale: Asking about alcohol intake is crucial in assessing the client's risk factors and behaviors, especially in the context of a suicide threat. Understanding alcohol consumption patterns can help the nurse evaluate potential substance abuse issues and their impact on the client's mental health. Choices A, B, and D are less pertinent to the immediate concern of assessing suicide risk and conduct disorder symptoms.

Correct Answer: A

Rationale: The correct answer is A: Perform weight-bearing exercises. Weight-bearing exercises are crucial for preventing bone density loss in clients with osteoporosis. These exercises help strengthen bones and reduce the risk of fractures. Option B, avoiding crossing the legs beyond the midline, is not directly related to preventing injury in osteoporosis. Option C, avoiding sitting in one position for prolonged periods, is important for preventing pressure ulcers but does not specifically address preventing injury in osteoporosis. Option D, splinting the affected area, is not a standard recommendation for preventing injury in osteoporosis.

Correct Answer: A

Rationale: When a patient refuses a blood transfusion for religious reasons, the healthcare provider should respect the patient's beliefs. It is crucial to uphold the patient's autonomy and right to make decisions about their care, even if the provider disagrees. Educating the patient on the importance of the transfusion may be appropriate in some cases, but the initial response should always be to respect the patient's decision. Notifying the healthcare provider is not necessary as the decision lies with the patient. Persuading the patient to accept the transfusion goes against the principle of respecting the patient's autonomy and beliefs.

Correct Answer: D

Rationale: The correct instruction the nurse should include is to rotate injection sites within the same anatomical region. This practice helps reduce the risk of lipodystrophy, a condition characterized by fatty tissue changes due to repeated insulin injections in the same spot. By rotating sites, the client ensures better insulin absorption and prevents localized skin changes. Injecting air into the vial before withdrawing insulin (Choice A) is unnecessary and not recommended. Drawing up short-acting insulin before long-acting insulin (Choice B) is not a standard practice and can lead to errors in dosing. Storing unopened insulin vials in the freezer (Choice C) is incorrect as insulin should be stored in the refrigerator, not the freezer, to maintain its effectiveness.
