Correct Answer: B

Rationale: During a manic episode, individuals with bipolar disorder may be easily overstimulated. Placing the client in a private room to decrease environmental stimuli is the priority intervention. This action can help reduce the risk of exacerbating manic symptoms and promote a calmer environment for the client. Choice A is not the priority as group therapy may be overwhelming during a manic episode. Choice C could potentially increase stimulation rather than decrease it. Choice D should not be the first action as sedatives are generally not the initial intervention for managing manic episodes.

Correct Answer: D

Rationale: In generalized anxiety disorder (GAD), common symptoms include restlessness, fatigue, and excessive worry. These symptoms are typical in individuals with GAD due to persistent and excessive anxiety. Mania, on the other hand, is not a characteristic symptom of GAD. Mania is associated with bipolar disorder and is characterized by distinct features like elevated mood, grandiosity, and impulsivity. Therefore, the correct answer is 'D: Mania,' as it does not align with the expected findings in generalized anxiety disorder.

Correct Answer: B

Rationale: In anorexia nervosa, individuals often develop lanugo, fine soft hair, on the face and back. This is a physiological response to the body's attempt to conserve heat due to a lack of subcutaneous fat. It is a common physical finding in clients with anorexia nervosa and can be a sign of severe malnutrition. Choices A, C, and D are incorrect because weight gain and increased appetite, increased body temperature and tachycardia, and hyperactivity and distractibility are not typically associated with anorexia nervosa. In fact, weight loss, decreased appetite, hypothermia, and bradycardia are more commonly seen in individuals with anorexia nervosa.

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: A

Rationale: The DSM-5 is a crucial tool in psychiatric nursing as it guides nurses in making accurate and reliable medical diagnoses of mental health conditions. Using the DSM-5 ensures that diagnoses are standardized, improving the quality and precision of care for clients. While the DSM-5 also supports a holistic view, interdisciplinary communication, and care plan development, its primary role in psychiatric nursing is to assist clinicians in diagnosing mental health conditions accurately.
