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: A

Rationale: The initial intervention for a client experiencing auditory hallucinations, especially in schizophrenia, is to assess the content of the hallucinations. By asking the client to describe the hallucinations, the nurse can determine if they are command hallucinations that might pose a risk. This assessment is crucial in guiding further appropriate interventions to ensure the client's safety and well-being. Instructing the client to ignore the hallucinations (Choice B) may not be effective, as the hallucinations are real to the client. Administering antipsychotic medication (Choice C) may be necessary but should come after assessing the situation. Engaging the client in reality-based activities (Choice D) is important but not the first priority when dealing with auditory hallucinations.

Correct Answer: D

Rationale: Potential side effects of ECT include short-term memory loss, headache, confusion, and nausea. Tardive dyskinesia is not a side effect of ECT; it is associated with long-term use of antipsychotic medications, particularly antipsychotics that block dopamine receptors over time. ECT is primarily used for severe depression, bipolar disorder, and certain psychotic disorders. The other choices, short-term memory loss, headache, and confusion, are known side effects of ECT and are usually short-term and manageable.

Correct Answer: C

Rationale: Common side effects of selective serotonin reuptake inhibitors (SSRIs) include nausea, insomnia, weight gain, and sexual dysfunction. Weight loss is not a common side effect associated with SSRIs. Therefore, the correct answer is C. While some individuals may experience weight changes while taking SSRIs, weight loss is less common compared to weight gain as a side effect of these medications.

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.
