A 63-year-old female comes to the Urgent Care Center with a chief complaint of cough for two weeks. She describes the cough as non-productive, dry, hacking, and it keeps her up at night. She also describes nasal congestion, an intermittent sore throat, and subjective fever. Her PMH is positive only for iron-deficiency anemia. She is on no routine medications. Her vital signs in your office are as follows: T – 37.2, BP – 114/66, HR – 68, RR – 16, SpO2 – 98% on room air. When you auscultate her lung fields, you appreciate no adventitious sounds. Your top differential diagnoses include viral upper respiratory illness, pneumonia, and GERD. You order a chest x-ray and review it in the Urgent Care center to decide on your best course of treatment for this patient.
