Which of the following is NOT part of proper hand hygiene practice?

• A. Lather all surfaces for at least 20 seconds.
• B. Keep hands lower than elbows during washing.
• C. Rinse all surfaces while keeping hands lower than elbows.
• D. Wipe hands dry with a towel without washing.

Answer: (D)

Proper hand hygiene means thoroughly cleaning all surfaces of the hands with soap and water (or sanitizer when appropriate) for a duration that removes germs. Lathering all surfaces for at least 20 seconds ensures the soap covers every area and has time to dislodge microbes. Keeping the hands below the elbows during washing and rinsing prevents contaminated water from flowing back onto the hands, helping maintain cleanliness as you rinse. Rinsing all surfaces while the hands stay below the elbows continues to protect against backflow contamination. After washing, drying the hands with a clean towel is part of the process, and the towel can be used to turn off the faucet. Wiping hands dry with a towel without washing would leave germs on the hands and is not part of proper hand hygiene practice.
