Correct Answer: A

Rationale: Positive symptoms in schizophrenia refer to excesses or distortions in normal behavior and include symptoms like hallucinations, delusions, and disorganized speech and behavior. Disorganized speech and behavior are considered positive symptoms because they represent an excess or distortion of normal functions. Negative symptoms involve deficits in normal behavior, cognitive symptoms affect thinking processes, and mood symptoms relate to emotional experiences. Therefore, in this scenario, the disorganized speech and behavior exhibited by the patient are classified as positive symptoms.

Correct Answer: A

Rationale: Exposure therapy is considered the most appropriate intervention for a patient with a phobia of flying. This therapeutic approach involves gradually exposing the individual to the feared stimulus, in this case, flying, in a controlled and supportive environment. By facing the fear in a structured manner, the patient can learn to manage their anxiety response and eventually reduce their phobia-related symptoms. While cognitive restructuring may help change negative thought patterns and medication management can alleviate symptoms, exposure therapy is specifically designed to address phobias through systematic desensitization, making it the most suitable intervention in this scenario. Psychoeducation aims to provide information and support but may not directly target the phobia itself.

Correct Answer: B

Rationale: Patients prescribed sertraline for major depressive disorder should be educated that it may take several weeks before experiencing the full therapeutic effects of the medication. This delay in onset of action is common with antidepressants like sertraline, and patients need to be aware of this to manage their expectations and continue with the treatment regimen. It's important for the patient to understand that consistent adherence to the prescribed dosage is crucial, even if the full effects are not immediately apparent. Choices A, C, and D are incorrect because taking the medication with food, avoiding grapefruit, and regular blood tests are not specific education points related to the expected timeframe for therapeutic effects of sertraline.

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: 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.
