A 29-year-old man presents with classic signs and symptoms of panic disorder. In addition to medication, the PMHNP will recommend which of the following forms of therapy?

Choice A reason: Existential therapy focuses on meaning and personal responsibility and is not evidence-based for panic disorder treatment. Choice B reason: Humanistic therapy emphasizes self-actualization and personal growth, with limited evidence for panic disorder. Choice C reason: Dialectical behavioral therapy is effective primarily for borderline personality disorder and emotion regulation, not first-line for panic disorder. Choice D reason: Cognitive behavioral therapy (CBT) is the gold standard for panic disorder, targeting maladaptive thought patterns and avoidance behaviors, and is strongly supported by evidence.
