“I have been short of breath and have been coughing up rust-colored phlegm for the past 3 days.”
James Thompson is a 55-year-old African-American man with a 3-day history of worsening shortness of breath, subjective fevers, chills, right-sided chest pain, and a productive cough. The patient states that his initial symptom of shortness of breath began approximately 1 week ago after delivering mail on an extremely cold winter day. He has been taking ibuprofen and an over-the-counter cough and cold preparation but feels that his symptoms are getting “much worse.” The patient began experiencing right-sided pleuritic chest pain and a productive cough with rust-colored sputum over the past 3 days and feels that he has been feverish with chills, although he did not take his temperature. On presentation to the ED, he is febrile and visibly short of breath.
