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: Offering family therapy sessions would be the most appropriate intervention for a client diagnosed with major depressive disorder. Family therapy can be beneficial as it addresses interpersonal relationships within the family system, which is crucial in managing major depressive disorder effectively. This approach aligns with Sullivan's interpersonal theory, which emphasizes the impact of interpersonal relationships on individual behavior and personality development. In contrast, encouraging discussion of feelings, discussing childhood events, or teaching alternate coping skills may not directly address the interpersonal dynamics contributing to the client's major depressive disorder.

Correct Answer: A

Rationale: The initial action the nurse should take is to encourage the client to talk about the traumatic event during the day. This approach can assist the client in processing the trauma in a controlled environment, potentially reducing the frequency and intensity of nightmares. It allows for emotional expression and may promote better sleep by addressing the underlying psychological distress associated with PTSD. Encouraging the client to talk about the event during the day promotes therapeutic processing of the trauma and emotional expression, which can lead to improved coping mechanisms and potentially decrease the distressing symptoms like nightmares. Encouraging the client to avoid caffeine and alcohol may be beneficial, but addressing the emotional aspects first is crucial. Administering a sedative should not be the first approach, as it does not address the root cause of the nightmares. Scheduling a follow-up appointment with the therapist is important but should follow addressing the immediate distressing symptoms and promoting coping strategies.

Correct Answer: B

Rationale: The question 'Have you ever experienced a similar stressful situation?' is the most appropriate as it assesses the client's coping resources and encourages reflection on past experiences. This question can help the client consider alternative ways to deal with stress. Asking about the cause of the stressful situation may provide insight into the current situation but does not directly assess coping abilities. Inquiring about blame does not focus on coping strategies but may encourage negative thinking and a sense of victimization. Questioning why the client was fired is a nontherapeutic approach that can hinder communication by putting the client on the defensive.

Correct Answer: C

Rationale: Interventions for a client with anorexia nervosa include monitoring daily caloric intake and weight, establishing a structured eating plan, providing liquid supplements as prescribed, and offering rewards for weight gain. However, encouraging the client to exercise is not appropriate as it may exacerbate the condition by increasing caloric expenditure and reinforcing unhealthy behaviors associated with the disorder. Exercise may further contribute to excessive weight loss and worsen the client's physical health in the context of anorexia nervosa.
