Which of the following is a common side effect of benzodiazepines prescribed for anxiety?

Correct Answer: C

Rationale: Drowsiness is a common side effect of benzodiazepines prescribed for anxiety. Benzodiazepines work by depressing the central nervous system, which can lead to drowsiness as a side effect. This sedative effect is often desired in the treatment of anxiety disorders, but individuals should be cautious when engaging in activities that require alertness, such as driving, while taking these medications. Insomnia, weight gain, and increased appetite are not typically associated with benzodiazepines; instead, drowsiness and sedation are more common side effects.

Correct Answer: B

Rationale: For a patient with agoraphobia, the priority intervention should be gradual exposure to feared situations. This approach helps the patient confront and gradually overcome their fear of leaving home, a common challenge in agoraphobia. By exposing the patient to feared situations in a step-by-step manner, they can learn to manage their anxiety and increase their confidence in leaving home. Teaching relaxation techniques (Choice A) can be beneficial but may not address the core issue of avoidance behavior. Encouraging the patient to attend social gatherings (Choice C) can be overwhelming and counterproductive at the initial stage of treatment. Providing education about the disorder (Choice D) is important but should come after addressing the immediate need for exposure therapy.

Correct Answer: B

Rationale: Lithium is a well-established mood stabilizer commonly prescribed for the treatment of bipolar disorder. It helps to control manic episodes, stabilize mood swings, and reduce the risk of relapse in individuals with this condition. Sertraline is an antidepressant commonly used for treating depression, while Clozapine and Haloperidol are antipsychotic medications used for different psychiatric conditions. Therefore, the correct answer is B because it is specifically indicated and effective for bipolar 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: B

Rationale: When initiating fluoxetine therapy in a patient with major depressive disorder, monitoring for suicidal ideation is crucial due to the increased risk of suicidal thoughts or behaviors that can occur, especially in the initial phase of treatment. This close monitoring is essential to ensure patient safety and intervene promptly if such symptoms arise. Weight gain, hypertension, and hyperglycemia are potential side effects of some medications used to treat depression, but suicidal ideation is the most critical and immediate side effect to monitor for when starting fluoxetine.
