Correct Answer: B

Rationale: The most crucial initial treatment goal for anorexia nervosa is restoring nutritional status. This is essential to prevent life-threatening complications associated with severe malnutrition, such as organ damage and cardiac issues. Addressing distorted body image, resolving family conflicts, and increasing social interactions are important aspects of treatment, but they are secondary to the critical need of restoring the patient's nutritional status to ensure their physical well-being and recovery.

Correct Answer: A

Rationale: Dialectical behavior therapy (DBT) is considered the most effective therapeutic approach for managing borderline personality disorder. DBT is a specialized form of cognitive-behavioral therapy that focuses on providing skills to cope with intense emotions, improve relationships, and regulate behavior. It has been extensively studied and shown to be effective in reducing self-harm, suicidal behaviors, and improving overall functioning in individuals with borderline personality disorder. Cognitive-behavioral therapy (Choice B) is a common and effective treatment for many mental health conditions but is not as specifically tailored to address the core symptoms of borderline personality disorder as DBT. Psychoanalysis (Choice C) is a more intensive and long-term therapy that focuses on exploring unconscious patterns and early life experiences, which may not be as practical or effective for the impulsive and emotional dysregulation seen in borderline personality disorder. Supportive therapy (Choice D) provides emotional support but lacks the structured skills training and strategies that are essential in managing borderline personality disorder.

Correct Answer: C

Rationale: The correct answer is dopamine. Dopamine dysregulation is a key factor in the development of schizophrenia. Excess dopamine activity in certain brain regions is associated with positive symptoms of schizophrenia, such as hallucinations and delusions. Dopaminergic medications that reduce dopamine levels are often used to manage these symptoms, further supporting the role of dopamine in schizophrenia. Serotonin (Choice A) is more commonly associated with mood regulation and is implicated in depression and anxiety disorders. Norepinephrine (Choice B) is involved in the body's 'fight or flight' response and is linked to conditions like anxiety and PTSD. Acetylcholine (Choice D) plays a role in muscle movement and memory but is not primarily implicated in schizophrenia.

Correct Answer: A

Rationale: Patients prescribed bupropion should be educated to avoid consuming alcohol while on this medication to reduce the risk of seizures. Bupropion lowers the seizure threshold, and alcohol can further increase this risk. It is important for patients to understand the potential consequences of combining bupropion with alcohol to ensure their safety and treatment effectiveness. Choices B, C, and D are incorrect. Taking bupropion in the morning does not prevent insomnia; it is not associated with significant weight gain; and it is not a first-line treatment for anxiety.

Correct Answer: C

Rationale: Extrapyramidal symptoms, such as tremors and rigidity, are frequently observed as side effects of antipsychotic medications. These symptoms result from the medications' influence on dopamine receptors in the brain. Choice A, hyperactivity, is not a typical side effect of antipsychotic medications. Choice B, weight loss, is less common compared to weight gain. Choice D, insomnia, though possible, is not as prevalent as extrapyramidal symptoms in individuals taking antipsychotic medications.
