Correct Answer: D

Rationale: The first action the nurse should take is to remove the client to a quieter environment. This intervention aims to reduce stimuli that may be contributing to the client's agitation and help create a calmer and more supportive setting for the client. Choices A, B, and C are not the priority in this situation as addressing the environmental factors should come first before exploring symptoms, offering medication, or engaging in relaxation exercises.

Correct Answer: A

Rationale: Encouraging the client to participate in daily activities is crucial in managing schizophrenia. Engaging in activities can enhance the quality of life and reduce symptoms by providing structure, routine, and social interaction, which are beneficial for individuals with schizophrenia. Choices B, C, and D are not the most appropriate instructions for managing schizophrenia. While expressing feelings can be helpful, daily activities have a more significant impact on managing the condition. Avoiding caffeine and spending time alone are not directly related to managing schizophrenia and may not be the most beneficial strategies.

Correct Answer: C

Rationale: The nurse should avoid challenging the client's delusions directly. Asking for more information can help the nurse understand the client's experience and build rapport.

Correct Answer: A

Rationale: Psychiatrists use pre-established criteria from the APA's Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to determine which diagnosis to give a patient. The DSM-5 is a comprehensive manual published by the American Psychiatric Association (APA) that outlines specific criteria for diagnosing mental disorders. It aims to ensure accurate and consistent diagnosis and treatment. Choices B and D provide inaccurate information. Hospital policy does not dictate psychiatric diagnoses, and the American Medical Association does not provide diagnostic labels for mental disorders. Choice C, although mentioning the assessment of patients, does not highlight the specific criteria and guidelines provided by the DSM-5 that psychiatrists use to assign diagnoses.

Correct Answer: B

Rationale: When caring for a client with borderline personality disorder, it is essential to encourage independence rather than dependency. This helps promote autonomy and self-reliance, which are important aspects of treatment. Setting clear and consistent boundaries is also crucial, as it provides structure and predictability. Avoiding discussing the client's feelings is not recommended, as addressing emotions and promoting emotional awareness is a key part of therapy. Using a firm, authoritative approach may not be the most effective strategy as it can lead to power struggles and conflicts in individuals with borderline personality disorder.
