The nurse observes an unlicensed assistive personal (UAP) washing hands prior to entering the client's room. Which action by the UAP requires additional teaching?

A. Lathering using a circular movement: Circular motions help ensure all surfaces of the hands are cleaned, including between fingers and around the thumbs, which is an appropriate technique during hand hygiene. B. Turning the water off using bare hands: Touching the faucet with bare hands after washing can recontaminate the hands, so a clean paper towel should be used to turn off the faucet to maintain hand hygiene. C. Holding hands below elbows when rinsing: Rinsing with hands below the elbows allows water and contaminants to flow away from the clean areas, helping maintain proper aseptic technique during hand washing. D. Washing for a total of 20 seconds: Washing hands for at least 20 seconds is consistent with CDC guidelines to effectively remove germs and reduce the risk of infection transmission.
