productive of small amounts of sputum and a runny nose. He does not take any medications, denies any
allergies, and has no significant medical history. Physical examination reveals a low-grade temperature of
99.9 degrees Fahrenheit, respirations of 16/min, a pulse of 90 beats per minute, and diffuse fine crackles
in the base of the lungs. A chest radiograph (x-ray) shows diffuse infiltrates on the lower lobe of the right
