Correct Answer: D

Rationale: Negative self-talk is a common cognitive symptom of major depressive disorder. It involves a pattern of negative thoughts and beliefs about oneself, which can significantly impact a patient's self-esteem and overall outlook on life. Hallucinations and delusions are more commonly associated with other mental health conditions like schizophrenia, while lack of appetite is typically considered a physical symptom of depression rather than a cognitive one.

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 taking the medication at the same time every day helps maintain consistent blood levels and effectiveness. Consistency in dosing is crucial for the medication to work optimally in managing symptoms of schizophrenia. Option B is incorrect because stopping the medication abruptly can lead to a worsening of symptoms. Option C is important as alcohol can interact with the medication and cause adverse effects. Option D is incorrect because risperidone is typically taken regularly, not on an as-needed basis, to manage symptoms effectively.

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: B

Rationale: Lithium is the medication frequently prescribed to stabilize mood in patients with bipolar disorder. It helps to reduce the frequency and severity of manic episodes, making it a cornerstone in the treatment of bipolar disorder. Sertraline is an antidepressant commonly used for depression, while haloperidol and diazepam are not typically first-line treatments for bipolar disorder.
