The correct donning order is gown first, then mask or respirator, followed by eye protection, and finally gloves, so that each layer is secured before the next is applied.

Question 5

A patient is diagnosed with Clostridioides difficile (C. diff) infection. Which hand hygiene approach is specifically required when caring for this patient?

Accepted Answer

Soap and water hand washing is required
