Texas Certified Nursing Assistant (CNA)

When washing hands, how long should a nursing assistant use friction?

1. At least 10 seconds

2. At least 20 seconds

3. At least 30 seconds

4. For as long as necessary until clean

The correct answer is: At least 20 seconds

When washing hands, using friction for at least 20 seconds is important for effectively removing germs and dirt. The friction generated by rubbing the hands together helps to dislodge and wash away contaminants from all surfaces of the hands, including between the fingers and under the nails, which are common areas for microbes to hide. This 20-second duration is backed by health organizations that suggest this length of time is necessary to ensure proper sanitation. By adhering to this guideline, nursing assistants can significantly reduce the risk of spreading infections and promote better hygiene in healthcare settings.
