Answer 1

In aseptic hand washing, it's important to use warm water and soap, wash hands vigorously for at least 20 seconds covering all areas, rinse thoroughly from wrist to fingertips, and dry hands with a clean towel.

Step-by-step explanation:

When performing aseptic hand washing, a medical assistant should take several critical steps to ensure the removal of microorganisms and prevent the spread of infection. These steps include:

• Wetting hands with warm water, which is preferable as it helps to remove oils that can harbor bacteria. Hands should be kept below the forearms during this process.
• Applying about 5 mL (1 teaspoon) of liquid soap and creating a lather. The hands should be rubbed together vigorously for at least 20 seconds. All areas of the hands must be cleaned, including the backs of the hands, between the fingers, and under the nails, using a nail brush if needed to remove debris.
• Rinsing hands thoroughly with water flowing from the wrist to the fingertips to make sure any dislodged microorganisms are washed away and not moved up the arms.
• Drying hands thoroughly with a clean towel or hot air blower and using a towel to turn off the faucets and open doors to avoid recontamination.

These methods are supported by the recommendations of the Centers for Disease Control and Prevention (CDC) for both the general public and health-care workers, particularly before and after patient contact or handling potentially infectious materials.
