Review Question - QID 109871

A 25-year-old medical student returns from a volunteer mission trip in Nicaragua with a persistent cough and occasional hemoptysis for 3 weeks. He has no significant medical history. His temperature is 98.6°F (37°C), blood pressure is 115/73 mmHg, pulse is 62/min, respirations are 12/min, and oxygen saturation is 99% on room air.

Among the prescribed medications, one drug inhibits carbohydrate polymerization of the pathogen's cell wall. Which of the following is the most likely side-effect/complication from use of this drug?
