Correct Answer: B

Rationale: During a manic episode in bipolar disorder, individuals may experience heightened energy levels, impulsivity, and decreased need for sleep. Providing a structured and low-stimulus environment is crucial in managing manic episodes. This intervention helps reduce overstimulation and provides a calm and predictable setting, which can be beneficial in helping the patient regain control and stability. Group activities and high-energy physical activities may exacerbate the symptoms of mania by increasing stimulation and excitement. Allowing the patient to set their schedule may not provide the necessary structure needed during a manic episode, hence making it less appropriate.

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: 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: Anhedonia, the inability to feel pleasure in activities that were once enjoyable, is a hallmark symptom of major depressive disorder. Patients with major depressive disorder often experience a pervasive feeling of emptiness and loss of interest in activities they used to find pleasurable. Euphoria, increased energy, and racing thoughts are more commonly associated with conditions like bipolar disorder rather than major depressive disorder.

Correct Answer: B

Rationale: The correct answer is B: Insomnia. Escitalopram, a selective serotonin reuptake inhibitor (SSRI), commonly causes insomnia as a side effect. Patients should be informed about the possibility of experiencing difficulty falling or staying asleep when starting this medication. Choices A, C, and D are incorrect because weight gain, diarrhea, and hypertension are not typically associated with escitalopram use.
