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.

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: A

Rationale: When a client presents with signs of distress and potential safety concerns, the priority is to provide a safe environment. Offering a safe place to relax can help the client feel secure and ready for further assessment and support. This action allows the nurse to establish rapport, ensure the client's immediate safety, and create a trusting relationship before delving into the details of the situation. Asking the client to describe why she is being stalked (Choice B) may exacerbate her distress and should come after ensuring her safety. Recommending that the client talk with a social worker (Choice C) is important but should follow immediate safety measures. Assuring the client that the healthcare provider will see her today (Choice D) is less critical than addressing her safety concerns and emotional state.
