AAntimicrobial soap and water at the sink
BPlain soap and water at the nearest sink
CRubbing hands with an alcohol-based rub
DA chlorhexidine scrub lasting two minutes
Answer & Solution
Correct answer: C. Rubbing hands with an alcohol-based rub
1. When hands are not visibly soiled, or after visible material has been removed with soap and water, hands are decontaminated.
2. The preferred method of decontamination is an alcohol-based hand rub.
3. Washing with an antimicrobial soap and water is named as the alternative rather than the preference.
4. Frequent use of an alcohol rub straight after washing with plain soap may increase dermatitis, so the two are not simply stacked.
