Correct Answer: B

Rationale: Prazosin is a medication often prescribed to manage nightmares in patients with PTSD. It works by blocking the action of adrenaline on specific receptors, which helps in reducing the intensity and frequency of nightmares. While flashbacks, hypervigilance, and depression are also common symptoms of PTSD, prazosin is specifically indicated for nightmares associated with the disorder. Flashbacks are typically addressed through therapies like cognitive-behavioral therapy, hypervigilance may be managed through counseling and coping strategies, and depression may necessitate antidepressant medications or therapy tailored for depression.

Correct Answer: C

Rationale: Cognitive-behavioral therapy (CBT) is considered the most effective therapeutic intervention for social anxiety disorder. CBT helps individuals identify and change negative thought patterns and behaviors associated with anxiety, leading to long-term symptom relief and improved coping strategies. Group therapy (choice A) can be beneficial as a complementary approach but may not be as effective as CBT for directly targeting individual cognitive and behavioral patterns. Behavioral rehearsal (choice B) is a technique used within CBT and not a standalone intervention for social anxiety disorder. Medication management (choice D) can be used as an adjunct to therapy in some cases but is not the first-line treatment for social anxiety disorder.

Correct Answer: C

Rationale: The most appropriate goal of cognitive-behavioral therapy (CBT) in treating generalized anxiety disorder (GAD) is to change the patient's negative thought patterns. This therapy focuses on identifying and modifying distorted thinking patterns that contribute to anxiety. Exploring childhood experiences (Choice A) may be part of therapy, but the primary focus is on present thoughts and behaviors. While medication (Choice B) can help manage symptoms, CBT aims to address the root cause through cognitive restructuring. Improving social skills (Choice D) is not the primary goal of CBT for GAD, although it may be a secondary benefit as confidence improves with reduced anxiety.

Correct Answer: A

Rationale: Weight gain is a common side effect of olanzapine, an atypical antipsychotic. Olanzapine is known to cause metabolic changes that can lead to weight gain. Monitoring weight regularly is essential to detect and manage this side effect to prevent associated health risks such as diabetes and cardiovascular issues. Hypotension (choice B) is not a common side effect of olanzapine. Olanzapine is more likely to cause orthostatic hypotension, which is a sudden drop in blood pressure when changing positions. Hair loss (choice C) and hyperthyroidism (choice D) are not typically associated with olanzapine use.

Correct Answer: A

Rationale: Memory loss, particularly short-term memory loss, is a common side effect of electroconvulsive therapy (ECT). ECT can affect memory due to its impact on brain function during and after treatment. While the memory issues are often temporary and tend to improve over time, they are important considerations when discussing the risks and benefits of ECT with patients. Choices B, C, and D are incorrect as weight gain, insomnia, and increased appetite are not common side effects of ECT.
