Correct Answer: D

Rationale: The correct answer is D: Inappropriate affect. Inappropriate affect refers to emotions that are not congruent with the situation. In this case, the patient's laughing while describing a horrifying image indicates a disconnect between his emotions and the context. This behavior is commonly seen in schizophrenia, where there is a lack of appropriate emotional response. A: Confusion does not accurately describe the patient's behavior, as he is able to describe the picture and his emotional response to it. B: Ambivalence refers to conflicting emotions or attitudes, which is not evident in the patient's behavior. C: Depersonalization involves feeling detached from oneself or reality, which is not evident in the patient's behavior. In summary, the patient's inappropriate laughter in response to a horrifying image is indicative of inappropriate affect, a common feature of schizophrenia.

Rationale: The correct answer is D because the nurse would expect the patient to demonstrate functional independence in activities like transferring from a wheelchair to the bed despite having a leg in a cast. This response indicates good mobility and strength, which are positive signs of recovery. Choices A, B, and C are incorrect as they do not directly address the functional assessment of the patient. Choice A provides historical information, choice B focuses on pain management, and choice C mentions a self-care routine that is not related to functional ability.

Correct Answer: A

Rationale: The correct answer is A: Administering supplemental oxygen as needed. This is the priority intervention for a patient with COPD because it helps improve oxygenation and relieve respiratory distress, which is the main concern in COPD. Supplemental oxygen also helps reduce the workload on the heart and other organs. Encouraging physical activity (B) is important for overall health but may not be the priority in acute exacerbations. Administering antibiotics regularly (C) is not necessary unless there is a documented infection. Providing increased fluid intake (D) is important for maintaining hydration but is not the priority intervention in this case.
