Correct Answer: D

Rationale: Nausea is a common side effect associated with sertraline, a medication commonly used in the treatment of generalized anxiety disorder (GAD). It is essential for the nurse to monitor for nausea as it can impact the patient's adherence to the medication regimen. Educating the patient about this potential side effect and advising ways to manage it can enhance treatment compliance and overall therapeutic outcomes.

Correct Answer: C

Rationale: Buspirone is a medication commonly prescribed for generalized anxiety disorder (GAD) due to its effectiveness and lower risk of dependency compared to benzodiazepines like diazepam. While fluoxetine and sertraline are selective serotonin reuptake inhibitors (SSRIs) often used for various anxiety disorders, buspirone is specifically indicated for GAD.

Correct Answer: A

Rationale: The correct answer is A because buspirone is not meant to be taken on an as-needed basis. It should be taken consistently to achieve optimal effectiveness in managing generalized anxiety disorder. Taking it as needed may lead to inadequate symptom control and reduced therapeutic benefits.

Correct Answer: B

Rationale: Teaching relaxation techniques is an appropriate intervention for a patient with PTSD experiencing nightmares. Relaxation techniques can help the patient manage anxiety and improve sleep quality, potentially decreasing the frequency and intensity of nightmares. By teaching relaxation techniques, the nurse empowers the patient to actively cope with and reduce the distressing symptoms of PTSD, contributing to overall therapeutic outcomes.

Correct Answer: B

Rationale: Regular monitoring of blood levels is crucial for patients taking risperidone to ensure the medication is at therapeutic levels and to prevent potential toxicity. This monitoring helps healthcare providers adjust the dosage as needed to optimize treatment outcomes and minimize adverse effects.
