    Here's this week's free sample question...

    A 5-month-old infant is brought to see you because of 3 days of watery diarrhea. Her parents report that she has had low-grade fevers, and anything she eats seems to come right out in her diaper. You order a test for C. difficile. 

    Which is true regarding this test in this patient?

    Answer Options:
    • Formula-fed infants are less likely to test positive for C. difficile than breastfed infants.

    • If the test returns positive, oral erythromycin should be started at the appropriate weight-based dose and retesting for cure should occur in 1-2 weeks.

    • If this patient were a newborn, a positive C. difficile test would be cause for great concern; in this patient, it is not.

    • Even with a positive test for C. difficile, other possible causes of this patient's diarrhea should be sought.
