A nurse is reinforcing teaching about hand hygiene with a newly licensed nurse. Which of the following information should the nurse include in the teaching?

A. Using hot water to wash hands is incorrect. Hot water can cause skin irritation and is not necessary for effective hand hygiene. The water temperature should be comfortable for the person washing their hands, whether it is warm or cool. B. Applying friction to hands for 10 seconds is incorrect. Hand hygiene should be done for at least 20 seconds, not just 10 seconds, to effectively remove contaminants. C. Drying hands starting from forearm to fingers is incorrect. Hands should be dried starting from the fingers to the forearms to avoid contamination from dripping water on the hands after washing. The goal is to maintain clean hands throughout the drying process. D. Interlacing the fingers while rubbing hands together is correct. Interlacing the fingers and rubbing them together ensures that all surfaces of the hands, including between the fingers, are properly cleaned. This method is recommended in the CDC hand hygiene guidelines for thorough washing.
