A nurse is caring for a toddler whose guardian reports multiple episodes of diarrhea. The provider suspects Clostridium difficile. Which of the following actions should the nurse take?
Correct answer
B
Rationale
A stool specimen for culture confirms Clostridium difficile by detecting toxins A and B, which cause severe diarrhea. Blood cultures are for systemic infections, 'C. diff test' is vague, and occult blood tests don't diagnose C. difficile.
