Which of the following is a proper step in hand hygiene practice?

The proper step in hand hygiene practice involves rinsing wrists and hands thoroughly. This step is vital to ensure that all soap, dirt, and microorganisms are effectively removed from the skin's surface. Proper rinsing helps prevent any contaminants from remaining on the skin, which could lead to infection or the spread of pathogens.

In addition, rinsing should be done with clean, running water to facilitate the removal of debris and pathogens, which emphasizes the importance of technique in achieving effective hand hygiene. It's essential to focus on thoroughness rather than speed to ensure that each area of the hands is cleaned and rinsed appropriately.
