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

A. Holding hands below elbows when rinsing is a correct technique to prevent contamination of washed hands. B. Lathering using a circular movement is a correct technique for thorough handwashing. C. Washing for a total of 20 seconds is in line with the recommended duration for effective handwashing. D. Turning the water off using bare hands can potentially recontaminate the hands. Instead, a paper towel or elbow should be used to turn off the faucet after washing hands to prevent recontamination. Therefore, this action by the UAP requires additional teaching.
