A 19-year-old homosexual college freshman presents to the student health clinic complaining of diarrhea of 2 days’ duration. He returned 9 days ago from a spring break trip to Mexico. His diarrhea is accompanied by prominent bloating, flatulence, nausea, and general malaise. On physical examination, he appears to be well hydrated, with a temperature of 36.9 C (98.4 F), blood pressure of 130/86 mm Hg, pulse of 89/min, and respirations of 18/min.

Which of the following is the most appropriate next step in management?
(A) Supportive care with IV fluids
(B) Treatment with ciprofloxacin
(C) Treatment with mebendazole
