30) A patient diagnosed with generalized anxiety disorder experiences debilitating panic attacks. Which medication is considered first-line pharmacologic treatment?

31) A 25-year-old patient with pediatric bipolar disorder is prescribed a combination of mood stabilizers and atypical antipsychotics. The rationale for this approach is primarily based on:
