What this question is testing
Objective: Infection Control
Prompt focus: A nursing assistant is about to provide perineal care for a resident with a known Clostridioides difficile infection. After removing gloves and gown, what is the most appropriate way to perform hand hygiene before leaving the room?
Why the correct answer works
Wash hands with soap and water for at least 20 seconds
Only soap and water with friction physically removes C. difficile spores, which alcohol cannot kill.
Why the tempting wrong answer fails
Water alone without soap and friction does not remove pathogens or spores effectively.
Plain-language takeaway
C. difficile spores are not killed by alcohol-based hand sanitizers, so soap and water with mechanical scrubbing for at least 20 seconds is required to physically remove spores from the hands. This is a key exception to the general rule that hand…
Simple analogy
Think of infection control like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
