Correct Answer: A

Rationale: The best response by the nurse is to explain that the medication will help stabilize the client's mood and prevent mood swings. This response provides the client with a clear understanding of how the medication works in managing bipolar disorder. Choice B is not the best response as it may cause unnecessary worry about lifelong medication dependence. Choice C is not as specific in addressing the purpose of the medication for bipolar disorder. Choice D is not as focused on the effect of the medication on mood stabilization, which is crucial in managing bipolar disorder.

Correct Answer: D

Rationale: The correct answer is D. Believing that the nurse is trying to poison him with pills is a clear indication of delusional paranoia, a common symptom in paranoid schizophrenia. Choices A, B, and C do not directly relate to paranoid delusions and are more indicative of hallucinations or other forms of delusions not specific to paranoia.

Correct Answer: B

Rationale: Encouraging the client to discuss their compulsions is the best nursing intervention when caring for a client with OCD who spends excessive time on hand-washing. This approach can help the client identify underlying anxieties and triggers associated with the compulsive behavior. Restricting access to soap and water (Choice A) can lead to increased anxiety and worsen the obsession. Allowing the client to continue the behavior (Choice C) can perpetuate the compulsive cycle. Scheduling distracting activities (Choice D) may provide temporary relief but does not address the root cause of the behavior.

Correct Answer: A

Rationale: The correct answer is A: 'You need to come in for regular blood tests.' Clozapine can cause agranulocytosis, a potentially life-threatening condition, so regular blood tests are required to monitor the client's white blood cell count. Choice B is incorrect because clozapine is associated with weight gain, not weight loss. Choice C is incorrect because the client should never stop taking clozapine abruptly due to the risk of withdrawal symptoms and symptom relapse. Choice D is incorrect because avoiding foods high in tyramine is typically associated with MAOIs, not clozapine.

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.
