D: Having a bag prepared with essentials ensures the victim can swiftly leave if required. A: Purchasing a gun can escalate violence and is not a recommended safety strategy.

Correct Answer: D

Rationale: In a situation where a client is agitated and physically aggressive, the priority for the RN is to ensure the safety of the client and others. Seeking assistance from other staff members is crucial as it allows for a prompt response to manage the situation effectively and according to the facility's protocol. Choices A, B, and C do not address the immediate need for safety or involve the collaboration of other staff members, which is essential in handling aggressive behaviors in a healthcare setting.

Correct Answer: B

Rationale: The correct answer is B. Elevated BUN levels may indicate renal impairment, which is crucial to report for clients on lithium due to its potential kidney effects. Option A, a serum lithium level of 0.8 mEq/L, is within the therapeutic range for lithium and does not require immediate reporting. Option C, a serum sodium level of 138 mEq/L, is within the normal range and not directly related to lithium therapy. Option D, urine output of 800 mL in 24 hours, may indicate a need for further assessment but is not the most critical finding to report compared to potential renal impairment indicated by an elevated BUN level.

Correct Answer: A

Rationale: Assessing the history of recent drug use is crucial when admitting a client with a history of substance abuse. Understanding recent drug use helps in managing potential withdrawal symptoms, preventing drug interactions with the new treatment, and ensuring appropriate care. Assessing current employment status (choice B) is important for social and financial support but is not as crucial as assessing recent drug use in this scenario. Family history of mental illness (choice C) and recent weight changes (choice D) are also important aspects of assessment but are not as immediate and critical as evaluating recent drug use in a client with a history of substance abuse.

Correct Answer: B

Rationale: The most important goal to achieve within the first three days of treatment is to ensure the client can sleep at least 6 hours a night. Adequate sleep is essential for stabilizing mood and improving overall functioning. Choice A is not as urgent as improving sleep patterns. Choice C is important but not as immediate as addressing the sleep deficit. Choice D is unrelated to the immediate treatment goal of improving sleep and managing symptoms of depression.
