A 42-year-old female with systemic lupus erythematosus is referred for urgent psychiatric evaluation by her rheumatologist. She was started on prednisone 60 mg daily twelve days ago for a severe lupus flare involving nephritis. Over the past five days, her husband reports she has become increasingly irritable, has been sleeping only two to three hours per night without feeling tired, has started three home renovation projects simultaneously, has made several large online purchases, and has been talking rapidly with pressured speech. She has no prior psychiatric history, no family history of bipolar disorder, and no history of substance use. Her SLE disease activity has improved on the corticosteroid course. Mental status examination reveals an elevated, expansive mood with flight of ideas, grandiosity about her renovation abilities, psychomotor agitation, and distractibility. Which assessment approach most accurately characterizes this psychiatric presentation?
