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. Apply friction to hands for 10 seconds: Effective hand hygiene requires rubbing hands together with friction for at least 20 seconds to remove pathogens. Ten seconds is insufficient to ensure proper cleaning and reduce infection risk. B. Interlace the fingers while rubbing hands together: Interlacing the fingers ensures that all surfaces, including the spaces between fingers, are cleaned thoroughly. This technique helps remove microorganisms from areas often missed during handwashing. C. Dry hands starting from forearm to fingers: Hands should be dried from fingers to forearm to prevent contamination from runoff water. Drying in the opposite direction can transfer pathogens back onto the hands. D. Use hot water to wash hands: Hot water is not recommended because it can cause skin irritation and dryness. Warm or lukewarm water is effective for hand hygiene while maintaining skin integrity.
