2. 15 seconds

3. 20 seconds

4. 30 seconds

The correct answer is: 20 seconds

When washing hands, using friction is a critical step in effectively removing dirt, germs, and bacteria. The recommendation to use friction for at least 20 seconds aligns with guidelines provided by health organizations, such as the Centers for Disease Control and Prevention (CDC). This duration enables sufficient physical action to dislodge pathogens from the skin and ensures thorough cleansing, especially in areas that are often missed, like between fingers and under nails. The emphasis on 20 seconds is based on research showing that this amount of time is optimal for maximizing the reduction of microbial presence on the hands. This practice, combined with proper technique—such as lathering with soap and rinsing thoroughly—contributes significantly to maintaining hygiene and infection control in a healthcare setting.
