Correct Answer: B

Rationale: Excessive worry is a characteristic feature of generalized anxiety disorder (GAD). Patients with GAD experience persistent and excessive worry about various aspects of their life, such as work, health, or family, even when there is little or no reason for concern. This chronic worrying can significantly impact their daily functioning and quality of life. Flashbacks are more commonly associated with post-traumatic stress disorder (PTSD), hallucinations are more typical in conditions like schizophrenia, while compulsive behaviors are seen in obsessive-compulsive disorder (OCD). Therefore, in the context of GAD, excessive worry is the symptom that the nurse is most likely to observe.

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: 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: 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: C

Rationale: The correct answer is C, Fluoxetine. Fluoxetine, a selective serotonin reuptake inhibitor (SSRI), is commonly prescribed to manage the depressive episodes in bipolar disorder. SSRIs are effective in treating the depressive phase of bipolar disorder as they help regulate serotonin levels in the brain, which can improve mood and reduce symptoms of depression. Choice A, Valproic acid, is used more commonly in the treatment of acute mania or mixed episodes in bipolar disorder. Choice B, Risperidone, is an atypical antipsychotic often used to manage psychotic symptoms in bipolar disorder. Choice D, Lithium, is primarily used for the maintenance treatment of bipolar disorder to prevent future manic and depressive episodes.
