Correct Answer: C

Rationale: The correct answer is C: Persecutory delusion. Persecutory delusions involve beliefs of being conspired against, watched, or harassed by others, which is a common symptom in schizophrenia. In this scenario, the client's belief that her brain is controlled by the CIA aligns with persecutory delusions as she feels targeted or manipulated by an external entity. Choices A, B, and D are incorrect. Somatic delusions involve false beliefs about one's body functions or sensations, paranoid delusions involve irrational suspicions and mistrust of others, and grandiose delusions involve exaggerated beliefs of one's importance or abilities.

Correct Answer: B

Rationale: The correct answer is B. Buspirone typically takes 2 to 4 weeks to become fully effective. It is essential to inform the client that it may take some time before they notice an improvement. Choice A is incorrect because buspirone does not work immediately. Choice C is also incorrect as buspirone does not provide immediate relief. Choice D is incorrect as it suggests a longer duration of treatment than necessary.

Correct Answer: A

Rationale: The most appropriate nursing intervention for a client with schizophrenia experiencing auditory hallucinations is to encourage the client to focus on reality-based activities. This intervention helps redirect their attention away from hallucinations, promoting engagement with the environment. Choice B is incorrect as telling the client that the voices are not real may invalidate their experiences and worsen the therapeutic relationship. Choice C may increase the client's distress by focusing on the hallucinations. Choice D might not be helpful as interacting with others who are not experiencing hallucinations may not address the client's current needs.

Correct Answer: A

Rationale: Encouraging the client to attend at least one group session is the best nursing intervention in this scenario. By gently encouraging participation, the nurse can help the client start to engage with others, which may gradually improve their mood and social interaction. Choice B, respecting the client's wish to remain isolated, may further exacerbate the client's withdrawal and depression by reinforcing avoidance behavior. Choice C, arranging for individual therapy sessions, can be beneficial but may not address the specific need for social interaction. Choice D, offering a list of activities to choose from, does not directly address the client's difficulty in participating in group activities and may not provide the necessary support in overcoming social withdrawal.

Correct Answer: C

Rationale: Initially, the nurse should allow time for the ritualistic behavior (C) to prevent anxiety. Administering an antianxiety medication (A) may help reduce the client's anxiety temporarily but will not address the underlying issue of ineffective coping mechanisms leading to the behavior. While assisting the client in identifying triggers (B) is important for long-term therapy, the immediate focus should be on managing the behavior. Teaching relaxation and thought-stopping techniques (D) is beneficial but might be more effective once the client is more stable and receptive to learning new coping strategies.
