A patient receiving a cephalosporin develops a secondary intestinal infection caused by Clostridium difficile. What is an appropriate treatment for this patient?
a. Adding an antibiotic, such as vancomycin (Vancocin), to the patient's regimen
b. Discontinuing the cephalosporin and beginning metronidazole (Flagyl)
c. Discontinuing all antibiotics and providing fluid replacement
d. Increasing the dose of the cephalosporin and providing isolation measures
ANS: B
Patients who develop C. difficile infection (CDI) as a result of taking cephalosporins or other antibiotics need to stop taking the antibiotic in question and begin taking either metronidazole or vancomycin. Adding one of these antibiotics without withdrawing the cephalosporin is not indicated. CDI must be treated with an appropriate antibiotic, so stopping all antibiotics is incorrect. Increasing the cephalosporin dose would only aggravate the CDI.
