Correct Answer: A

Rationale: Setting a specific limit on the checking behavior is the most appropriate intervention for a client with OCD who repeatedly checks the door and seeks reassurance. This approach helps the client gradually reduce the compulsive behavior, promotes independence, and supports progress in treatment. Choice B is not the most suitable intervention as it does not directly address the compulsive checking behavior. Choice C, providing consistent reassurance, may reinforce the compulsive behavior and hinder treatment progress. Choice D of ignoring the behavior does not actively assist the client in managing their symptoms and addressing the underlying disorder.

Correct Answer: D

Rationale: During an exacerbation of schizophrenia symptoms, the nurse should prioritize assessing for safety risks. This is critical because individuals with schizophrenia may experience heightened risks to themselves or others during this period. Encouraging adherence to the medication regimen (Choice A) is important but ensuring immediate safety takes precedence. Increasing social interactions with peers (Choice B) and providing a high-stimulation environment (Choice C) can potentially exacerbate symptoms and should be avoided during an exacerbation.

Correct Answer: C

Rationale: The correct side effect that the nurse should monitor for in an elderly client diagnosed with delirium and treated with antipsychotic medication is orthostatic hypotension. Antipsychotic medications can lead to a drop in blood pressure upon standing, particularly in elderly individuals. Akathisia (choice A) refers to a movement disorder characterized by a feeling of inner restlessness and a compelling need to be in constant motion, which can be a side effect of antipsychotic medications but is not specific to elderly clients with delirium. Hallucinations (choice B) are sensory perceptions that appear real but are created by the mind, and while they can be associated with certain conditions or medications, they are not a common side effect of antipsychotic medications in elderly clients with delirium. Drowsiness (choice D) is a general CNS depressant effect that can occur with antipsychotic medications but is not the specific side effect that the nurse should be monitoring for in this case.

Correct Answer: B

Rationale: Acknowledging the impact of the sister's comments on the client helps validate the client's feelings and supports therapeutic dialogue.

Correct Answer: B

Rationale: Monitoring vital signs is the priority action to ensure the physiological stability of a client with delirium tremens. In this scenario, the client's dehydration, confusion, and other symptoms necessitate close monitoring of vital signs to assess their condition accurately. Encouraging oral fluids (Choice A) is important for hydration but does not directly assess physiological stability. Keeping the room dark (Choice C) may help with hallucinations but is not the primary intervention for physiological stability. Applying ice to the tongue (Choice D) addresses a symptom but is less critical compared to monitoring vital signs in this situation.
