In client teaching about hand hygiene, what should the nurse emphasize as the most important aspect?

Emphasizing the importance of washing hands for at least 20 seconds with soap and water is crucial in the context of hand hygiene because this duration is fundamental for effectively removing pathogens. Studies have shown that handwashing with soap and water, when performed correctly, significantly reduces the number of microorganisms on hands. The mechanical action of scrubbing creates friction that helps dislodge dirt, grease, and germs, while the soap acts to lift these contaminants away from the skin, which is not always as effective with hand sanitizers alone.

While antibacterial soap can be beneficial in certain contexts, it is not always necessary, as regular soap is effective in removing germs. Likewise, using hand sanitizer provides a convenient alternative when soap and water are not available, but it may not eliminate all types of germs, particularly if hands are visibly dirty or greasy. Avoiding the face helps prevent the introduction of pathogens into the body, but it does not replace the need for proper hand hygiene. Therefore, the most effective practice and emphasis in the teaching of hand hygiene centers around the duration and technique of washing hands with soap and water.
