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: 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: The widow's symptoms align more closely with an adjustment disorder rather than major depression, normal grieving, or posttraumatic stress disorder. The widow's prolonged struggle in coping with the loss, characterized by emptiness, loss of self, difficulty envisioning the future, and anger towards her deceased husband, indicates an inability to adapt to the loss. These symptoms are indicative of an adjustment disorder, which typically arises in response to a significant life stressor and persists beyond what is considered a normal grieving process. Bereavement counseling can help the widow navigate her emotions and coping strategies during this challenging period.

Correct Answer: C

Rationale: Corrected Rationale: Selective serotonin reuptake inhibitors (SSRIs) are commonly associated with sexual dysfunction as a side effect. This adverse effect includes decreased libido, delayed orgasm, and erectile dysfunction. Educating patients about this potential side effect is crucial to manage expectations and consider appropriate interventions. Choices A, B, and D are incorrect as SSRIs are not typically associated with hypertension, diarrhea, or weight gain as common side effects.

Correct Answer: B

Rationale: Patients prescribed fluoxetine should be educated that the medication may take several weeks to achieve its full therapeutic effect. This information helps manage patient expectations and ensures they do not discontinue the medication prematurely due to lack of immediate results. Taking the medication in the morning to avoid insomnia is not a specific requirement for fluoxetine. Consuming alcohol while taking fluoxetine is not safe and can lead to adverse effects. It is crucial to report any side effects to the healthcare provider promptly for timely management and adjustment of the treatment plan.
