Rationale: Maintaining a consistent sodium intake is crucial for clients taking lithium because changes in sodium levels can impact lithium concentrations, potentially leading to toxicity. It is essential to avoid excessive sodium intake, as both low and high levels can affect lithium levels. Choices A, B, and D are incorrect. A high potassium diet is not a concern with lithium therapy. While taking lithium with food can help reduce gastrointestinal side effects, it is not the most important instruction.

Rationale: The most appropriate nursing intervention for a client with schizophrenia experiencing auditory hallucinations is to encourage them to engage in reality-based activities. This intervention helps manage auditory hallucinations by redirecting the client's focus away from the hallucinations. Choice A is not recommended as it may exacerbate the hallucinations or distress the client. Choice B is incorrect because denying the reality of the voices can invalidate the client's experiences. Choice D, asking the client to focus on positive thoughts, may not be effective in addressing the auditory hallucinations directly.

Correct Answer: B

Rationale: The most important teaching point for the LPN/LVN to reinforce is to avoid drinking alcohol while taking lorazepam (Ativan). Alcohol can enhance the sedative effects of lorazepam, increasing the risk of severe side effects and complications. Choice A is incorrect because lorazepam can be taken with or without food. Choice C is not the most critical teaching point, although it is essential to avoid activities that require mental alertness until the effects of the medication are known. Choice D is incorrect because abruptly stopping lorazepam can lead to withdrawal symptoms and should only be done under medical supervision.

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: 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.
