Maria is a 36-year-old who presents for evaluation of a cough. She is normally a healthy young lady with no significant medical history. She takes no medications and does not smoke. She reports that she was in her usual state of good health until approximately 3 weeks ago when she developed a "really bad cold." The cold is characterized by a profound, deep, mucus-producing cough. She denies any rhinorrhea or rhinitis-the primary problem is the cough. She develops these coughing fits that are prolonged, very deep, and productive of a lot of green sputum. She hasn't had any fever but does have a scratchy throat. Maria has tried over-the-counter cough medicines but has not had much relief. The cough keeps her awake at night and sometimes gets so bad that she gags and dry heaves.
