Verified step by step guidance

1. Understand the purpose of a surgical scrub: It is a procedure to remove or kill microorganisms on the skin to prevent infection during surgery.
2. Recognize the importance of hand positioning: Keeping hands higher than elbows ensures that water and contaminants flow away from the hands, preventing them from reaching the forearms.
3. Consider the role of gravity: By positioning hands above elbows, gravity helps direct water and any potential contaminants downwards, away from the cleanest part of the arms.
4. Acknowledge the risk of contamination: If hands are lower than elbows, water can carry contaminants from the hands to the forearms, increasing the risk of contamination.
5. Emphasize the goal of maintaining sterility: The primary goal of the surgical scrub is to maintain sterility, and proper hand positioning is crucial to achieving this.
