المصادر مختلفة. ملفات الدفعة فيها إجابتين، وما نرجّح وحدة على الثانية. سبب كل وحدة في الشرح تحت:
- إجابة: D. E. coli enterotoxin (ETEC)
- إجابة ثانية: A. Ova and parasites
The stem is incomplete: it gives no symptoms, so it presumably means traveler's diarrhea. Enterotoxigenic E. coli (ETEC) is the classic cause of traveler's diarrhea ("Montezuma's Revenge", linked to Mexico), which is why the bank keys D. However, the cohort material says most traveler's diarrhea is self-limited and testing is usually not indicated. When testing is done (severe or prolonged cases), it lists stool culture and microscopy for ova and parasites, not an ETEC enterotoxin assay. So A is also defensible.

Disputed. Supported by the clinical notes on traveler's diarrhea: most cases are self-limited, and if severe, prolonged or atypical the tests are stool culture and microscopy for ova and parasites.

C. difficile follows antibiotic exposure, which disturbs the normal gut flora. A traveler returning from Mexico has no such history.

Blood cultures are for systemic illness, which is not described, not for a returning traveler in general.

Disputed. Supported by the diarrhea notes: ETEC is listed as the cause of travelers' diarrhea ("Montezuma's Revenge"), which fits a traveler just back from Mexico.
