Correct Answer: A

Rationale: Acute confusion is the priority problem as it directly affects the client's ability to process information and make safe decisions. In this scenario, the client's disorientation, disorganization, and confusion indicate an immediate cognitive issue that requires attention to ensure her safety and stability. Choices B, C, and D are not the priority problems in this case. Ineffective community coping, disturbed sensory perception, and self-care deficit, while important, are secondary to the client's acute confusion, which poses an immediate risk to her well-being.

Correct Answer: D

Rationale: Reassessing the client's mental status is the most important intervention as it is crucial to address the client's delusional thinking. By assessing the client's thought processes and content, the nurse can gain insight into the client's beliefs and tailor interventions accordingly. Reassuring the client that no harm will come to her, asking the healthcare provider to give the medication, or simply explaining the importance of taking the medication may not effectively address the underlying issue of delusional beliefs.

Correct Answer: D

Rationale: The correct response is D. Respecting the client's privacy while acknowledging the difficulty of the situation and explaining the professional obligation to maintain confidentiality is the most therapeutic approach. This response shows empathy, understanding, and a commitment to confidentiality, which can help build trust and encourage the client to open up. Choices A, B, and C do not effectively address the client's concerns or emphasize the importance of confidentiality in a sensitive manner, making them less therapeutic responses in this situation.

Correct Answer: D

Rationale: A negative view of self and the future (D) is a prominent characteristic of depression. It reflects the core symptoms of low self-esteem and hopelessness that are commonly associated with this condition. Grandiose ideation (A) and suspiciousness of others (C) are more indicative of other mental health disorders like paranoia. While self-destructive thoughts (B) can be present in depression, they are not as specific and common as the negative self-view and hopelessness, making option (D) the most indicative characteristic of depression.

Correct Answer: B

Rationale: The correct answer is to instruct the client to drink plenty of fluids, especially during hot weather. Maintaining adequate hydration is crucial for clients taking lithium as dehydration can lead to lithium toxicity. Choice A is incorrect because while it is important to monitor sodium intake, staying hydrated is more critical. Choice C is incorrect as lithium is usually recommended to be taken with food to reduce stomach upset. Choice D is also important but not the most crucial instruction compared to ensuring proper hydration.
