Correct Answer: D

Rationale: A mental status examination is the most important assessment for the nurse to obtain in this scenario. It provides a comprehensive view of the client's current cognitive functioning, including their level of alertness, orientation, memory, attention, and thought process. Understanding the client's mental status is crucial for developing an appropriate treatment plan. The other options, such as motivation for treatment, history of substance use, and medication compliance, are important aspects to consider but may not directly address the client's current cognitive state and immediate treatment needs as effectively as a mental status examination.

Correct Answer: C

Rationale: The correct answer is C: Insomnia. Insomnia is a common side effect of SSRIs, including those used to treat generalized anxiety disorder (GAD). Educating the client about potential side effects like insomnia is crucial for managing expectations and promoting treatment adherence. Weight loss (choice A) is less common with SSRIs and might not be a primary concern for a client with GAD. Increased appetite (choice B) is also less likely with SSRIs. Dry mouth (choice D) is a side effect more commonly associated with other classes of medications, such as anticholinergics, rather than SSRIs.

Correct Answer: C

Rationale: The CAGE questionnaire focuses on the client's self-perception and behaviors related to drinking, such as efforts to cut down and guilt.

Correct Answer: B

Rationale: The client's recent history of divorce, job loss, and breakup of a current relationship indicates a series of significant losses. These losses are likely the primary source of his feelings of depression, leading to a sense of loss. While feelings of frustration (choice A) and poor self-esteem (choice C) could be contributing factors, the immediate trigger for his current emotional state appears to be the series of losses. A lack of intimate relationships (choice D) may be a consequence of the client's depressive symptoms rather than the root cause in this scenario.

Correct Answer: B

Rationale: Establishing trust by providing a calm and safe environment is crucial for the success of desensitization therapy in clients with agoraphobia. This approach helps the client feel safe and secure, allowing them to gradually confront their fear of crowds. Encouraging positive thoughts (choice A) is beneficial but not as immediately critical as creating a safe space. Progressively exposing the client to larger crowds (choice C) should occur after trust is established and in a controlled manner. Encouraging deep breathing (choice D) is helpful, but creating a safe environment takes precedence to build a foundation for successful desensitization.
