Which therapeutic approach is considered most effective for treating posttraumatic stress disorder (PTSD)?

Correct Answer: A

Rationale: Cognitive processing therapy is a specialized form of cognitive-behavioral therapy that has been shown to be highly effective in treating posttraumatic stress disorder (PTSD). This therapy focuses on helping individuals process and make sense of their traumatic experiences, leading to symptom reduction and improved coping mechanisms. Psychoanalysis, medication management, and group therapy can be beneficial in some cases, but cognitive processing therapy is specifically tailored for addressing the symptoms and underlying causes of PTSD. Psychoanalysis may not be as effective for PTSD due to its focus on unconscious conflicts rather than trauma processing. Medication management can be useful as an adjunct to therapy but does not address the core issues of PTSD. Group therapy can provide support but may not offer the individualized approach that cognitive processing therapy provides.

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: 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: 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.

Correct Answer: B

Rationale: When a patient with PTSD is experiencing flashbacks, the most appropriate intervention is to help them reorient to the present. This intervention can assist in reducing the intensity of the flashback and providing a sense of safety for the patient. Choice A is incorrect because encouraging the patient to talk about the trauma during a flashback may exacerbate their distress. Choice C is incorrect as leaving the patient alone can increase their feelings of isolation and fear. Choice D is incorrect because reminding the patient that the flashback is not real may invalidate their experience and increase their sense of disconnection.

Correct Answer: C

Rationale: When a patient with schizophrenia is prescribed clozapine, regular monitoring for agranulocytosis is essential. Agranulocytosis is a severe reduction in white blood cells that can be life-threatening. Monitoring white blood cell counts is crucial to detect this side effect early and prevent serious complications. Weight loss (Choice A) is not a common side effect of clozapine. Hypertension (Choice B) and hyperthyroidism (Choice D) are also not typically associated with clozapine use, making them incorrect choices for regular monitoring.

Correct Answer: C

Rationale: Extrapyramidal symptoms, such as tremors and rigidity, are frequently observed as side effects of antipsychotic medications. These symptoms result from the medications' influence on dopamine receptors in the brain. Choice A, hyperactivity, is not a typical side effect of antipsychotic medications. Choice B, weight loss, is less common compared to weight gain. Choice D, insomnia, though possible, is not as prevalent as extrapyramidal symptoms in individuals taking antipsychotic medications.

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: C

Rationale: The correct answer is C, 'Sexual dysfunction.' Paroxetine, an SSRI commonly prescribed for OCD, can lead to sexual dysfunction as a side effect. Patients should be educated about this potential adverse effect to ensure they are aware and can seek appropriate management if needed. Choices A, B, and D are incorrect because insomnia, weight loss, and hypertension are not typically associated with paroxetine use as common side effects in patients with OCD.
