What order should a nurse follow up on for a patient with C. Diff?

In the management of a patient with Clostridium difficile infection (C. Diff), the priority would be to administer the proper treatment indicated for the infection. In this case, the correct choice is the prescription for oral Flagyl (metronidazole). This medication is an antibiotic specifically used to treat C. Diff infections. By administering Flagyl, the nurse is directly addressing the cause of the infection, which is essential for the patient's recovery.

In contrast, probiotics are often considered as adjunct therapy to help restore gut flora but do not directly combat the infection itself. While encouraging fluid intake is important to prevent dehydration, especially if the patient is experiencing diarrhea, it is not a primary treatment for the infection. Imodium (loperamide) is an anti-diarrheal medication and is contraindicated in C. Diff infections because it can worsen the condition by slowing down the elimination of the bacteria from the intestines. Thus, the best practice in this scenario is to prioritize the administration of Flagyl to effectively treat the infection.
