Question 2 of 5
52 y/o recently traveled to Puerto Rico for 3 months. He developed fatigue, malaise, and abdominal cramps I week after returning followed by diarrhea and dyspepsia. Stools are 'oatmeal-like'. Labs: Hgb: I I. 3 (MCVI03). Stool studies are negative for Enteric Pathogens. Enteroscopy is performed. What is the most likely diagnosis?
Correct Answer: C
Rationale: Tropical sprue is a malabsorptive condition linked to prolonged travel in tropical regions like Puerto Rico, presenting with diarrhea, fatigue, and macrocytic anemia (MCV 103). Negative stool studies rule out Giardia, and celiac requires biopsy confirmation.

Question 5 of 5
An otherwise healthy 32 y.o. is seen in your office/ER soon after a cat bite. Typical of cat bites, the wound demonstrates several small puncture wounds that are not really amenable to irrigation or other wound care. Should you give an antibiotic? If so, which one would be considered a poor choice?
Correct Answer: A
Rationale: Cephalexin (Keflex®) is a poor choice because it doesn't cover Pasteurella multocida, a common pathogen in cat bites.
