A patient diagnosed with bipolar disorder is experiencing a depressive episode. Which medication is commonly prescribed for this phase of the disorder?

Correct Answer: C

Rationale: The correct answer is C, Fluoxetine. Fluoxetine, a selective serotonin reuptake inhibitor (SSRI), is commonly prescribed to manage the depressive episodes in bipolar disorder. SSRIs are effective in treating the depressive phase of bipolar disorder as they help regulate serotonin levels in the brain, which can improve mood and reduce symptoms of depression. Choice A, Valproic acid, is used more commonly in the treatment of acute mania or mixed episodes in bipolar disorder. Choice B, Risperidone, is an atypical antipsychotic often used to manage psychotic symptoms in bipolar disorder. Choice D, Lithium, is primarily used for the maintenance treatment of bipolar disorder to prevent future manic and depressive episodes.

Correct Answer: A

Rationale: Cognitive-behavioral therapy (CBT) is widely recognized as the most effective treatment for phobias. CBT helps individuals identify and change negative thought patterns and behaviors associated with their phobias, leading to long-lasting improvement and symptom reduction. Unlike psychoanalysis, which focuses on exploring unconscious conflicts, CBT provides practical strategies to address phobias directly. Medication management may be used in conjunction with therapy but is not typically considered a standalone treatment for phobias. Group therapy can be beneficial for some individuals, but CBT is specifically tailored to target and alleviate phobia symptoms effectively.

Correct Answer: A

Rationale: Exposure and response prevention (ERP) is the most appropriate therapy for managing OCD. ERP involves exposing the patient to anxiety-provoking stimuli (such as touching dirty objects) and preventing the compulsive response (hand washing), thus helping the patient learn to tolerate the anxiety without performing the ritualistic behavior. Dialectical behavior therapy (DBT) focuses more on emotional regulation and interpersonal skills, making it less suitable for directly addressing OCD symptoms. Family therapy and interpersonal therapy may be beneficial for other conditions or relationship issues but are not specifically designed to target OCD symptoms like ERP.

Correct Answer: C

Rationale: When a patient with schizophrenia is prescribed clozapine, regular monitoring for agranulocytosis is essential. Agranulocytosis is a severe reduction in white blood cells that can be life-threatening. Monitoring white blood cell counts is crucial to detect this side effect early and prevent serious complications. Weight loss (Choice A) is not a common side effect of clozapine. Hypertension (Choice B) and hyperthyroidism (Choice D) are also not typically associated with clozapine use, making them incorrect choices for regular monitoring.

Correct Answer: B

Rationale: Buspirone is often chosen as a first-line treatment for generalized anxiety disorder (GAD) due to its efficacy and favorable side effect profile. Unlike benzodiazepines such as clonazepam (A), buspirone does not carry the risk of tolerance, dependence, or withdrawal symptoms, making it a preferred choice. While propranolol (C) and hydroxyzine (D) are sometimes used for anxiety, they are not typically considered first-line treatments for GAD.
