• A. Wet hands, apply soap, scrub for at least 20 seconds, rinse, dry with a clean towel.
• B. Apply soap, wet hands, scrub for 10 seconds, rinse, dry.
• C. Wet hands, rinse, apply soap, scrub for 20 seconds, dry with a towel.
• D. Wet hands, apply soap, rinse, scrub 5 seconds, dry.

Answer: (A)

Hand hygiene before patient contact works best when you wet hands, apply soap, scrub for at least 20 seconds, rinse, and dry with a clean towel. Wetting hands first helps the soap lather and lift contaminants. Applying soap and rubbing all surfaces—palms, backs of hands, between fingers, and under nails—for at least 20 seconds provides enough mechanical action to dislodge germs. Rinsing afterward washes away the loosened microbes, and drying with a clean towel prevents recontamination that could happen from a dirty or shared towel. This sequence minimizes the chance of transferring pathogens to the patient or environment. Shorter scrubbing times or altering the order (such as rinsing before scrubbing or drying with a non-clean towel) reduce effectiveness and can increase contamination risk.
