Five days after undergoing surgical repair of a hip fracture, a 71-year-old man is agitated and confused. Last night, he had to be restrained multiple times after attempting to leave his room. His overnight nurse reported that at times he would be resting, but shortly afterward he would become agitated again for no clear reason. He has hypertension and COPD. He had smoked one pack of cigarettes daily for 50 years but quit 10 years ago. He drinks 1 glass of whiskey per day. His current medications include oxycodone, hydrochlorothiazide, albuterol, and ipratropium. He appears agitated. His temperature is 37°C (98.6°F), pulse is 72/min, and blood pressure is 141/84 mm Hg.
