When using alcohol-based surgical hand scrub products for surgical hand antisepsis, the first step is to?

• A. Apply scrub directly to dry hands
• B. Prewash hands and forearms with non-antimicrobial soap and water and dry, then apply scrub and air dry
• C. Rinse with water
• D. Use cold water

Answer: (B)

The first step is to prewash with non-antimicrobial soap and water for mechanical dirt removal, then dry thoroughly before applying the alcohol-based antiseptic. This sequence reduces the bioburden on the hands and forearms so the alcohol-based product can work effectively. Drying is important because moisture can dilute the antiseptic and shorten its contact time, making the rub less effective. After drying, you apply the alcohol-based scrub and allow it to air dry to complete the antisepsis before donning gloves. Rinsing with water or using cold water doesn’t address soil removal first or skin drying, and applying the antiseptic to dirty or wet hands would reduce efficacy.
