Chief Complaint
A 58 y.o. presents with fatigue and difficulty catching her breath. Although she has frequently coughed for months, the fatigue and shortness of breath have come on over the past 2 months. She has been treated twice in the past year for bronchitis, which included a severe cough with yellow sputum, shortness of breath, and fever. Once treated, the shortness of breath resolved until recently. She is a former smoker, describing a 40-pack-a-year history, finally quitting successfully on her 58th birthday.
