Sample QuestionA 73-year-old man with hypertension, coronary artery disease, and diabetes mellitus presents to your office complaining of cough and shortness of breath. He reports that for the past 3 or 4 days, he has been experiencing progressive dyspnea on exertion, and he now has mild dyspnea at rest. He also states that he has been having fevers, chills, and purulent sputum production over this period. He denies having come into contact with anyone who was sick. Results of physical examination are as follows: blood pressure, 124/87 mm Hg; heart rate, 95 beats/min; respiratory rate, 26 breaths/min; temperature, 101.3° F (38.5° C); and oxygen saturation on room air, 88%. The patient exhibits tachypnea without the use of accessory muscles. Bronchial breath sounds are noted over the right lower lung zones consistent with consolidation. A chest radiograph in the office confirms a right lower lobe infiltrate. You plan to admit the patient to the hospital for intravenous antibiotics and further monitoring. Which of the following is a likely cause of this patient's low oxygen saturation?
