If a handwashing observation shows a 5-second scrub, what should be done next?

• A. Rinse for 5 seconds
• B. Reapply soap and scrub for 10 to 15 seconds
• C. Dry with a towel for 2 seconds
• D. Use hand sanitizer after washing

Answer: (B)

A longer, thorough hand scrub is needed to remove dirt and microorganisms effectively. Five seconds of scrubbing doesn’t provide enough mechanical action to clean the skin, so the next step is to reapply soap and scrub for about 10 to 15 seconds, making sure all surfaces are covered—including the palms, backs of the hands, between the fingers, and under the nails. After that extended scrub, rinse well and dry properly. Rinsing for only 5 seconds right after a short scrub wouldn’t remove as much residue, drying for just 2 seconds isn’t adequate, and hand sanitizer isn’t a substitute for proper washing when soap and water are available.
