A 4-year-old boy has a 2-day history of runny nose, productive cough, and wheezing. He has notable fever and decreased appetite from past two days. On examination, he is febrile, at 103.2°F (39.6°C), with a respiratory rate of 22 breaths/min. He has no known cardiorespiratory disease, and his immunizations are current.
