You are working at a night clinic as a nurse practitioner and are assessing a 35-year- old male who is complaining of mild-grade fever and a persistent, productive cough that at times appears to have blood. He states he has lost weight in the past 6 months and often wakes up drenched in sweat. He has treated his symptoms with over-the-counter medications but feels that his symptoms are worsening. He had recently traveled to India on business.
