A 42-year-old female has smoked since she was 18 years old. She has noticed a mild, occasionally productive cough for the past 3-4 months. The cough is worse whenever she spends the night out in the country where she is exposed to the smoke of campfires. She has been smoking about one pack per day for the last 20 years. While she has only had a productive cough for the last 3-4 months, she has had a nonproductive cough for almost a year. She has had no fever or chills. She does admit to more shortness of breath when she exercises over the past six months. Her only other past medical history includes hypertension for which she is using lisinopril, metoprolol, and hydrochlorothiazide.
