A 24-year-old man presents to the PMHNP with complaints of worsening mental health symptoms after an extended period of isolation during COVID-19 quarantine. He now reports inability to go grocery shopping, use public transportation, or leave home on most days, due to fear of being unable to obtain help if he experiences an "anxiety attack." Which of the following most accurately describes his condition?

Choice A reason: Social anxiety disorder primarily involves fear of social situations in which one might be judged, rather than fear of being unable to obtain help in public settings. Choice B reason: Generalized anxiety disorder is characterized by excessive worry about various life events, not situational avoidance due to fear of panic or being trapped. Choice C reason: Agoraphobia involves fear and avoidance of situations where escape might be difficult or help unavailable in the event of panic-like symptoms. The patient’s avoidance of public spaces aligns directly with this disorder. Choice D reason: Panic disorder involves recurrent panic attacks, which may occur without situational triggers. While panic is relevant, the defining feature here is avoidance behavior consistent with agoraphobia.
