Final answer:
In healthcare settings, instruments like handpieces should be flushed and sterilized as per the guidance provided by the manufacturer's instructions and AST. Hands should be washed for at least 20 seconds or more, depending on the situation, to prevent infection spread.
Step-by-step explanation:
Handpieces and instruments used in medical settings should be thoroughly flushed and sterilized between each patient to prevent cross-contamination and the spread of infection. The Association of Surgical Technologists (AST) suggests that protocols for the length of time required for surgical scrubbing may vary depending on the antimicrobial product used. Healthcare workers should always refer to the manufacturer's instructions for guidance on the duration and proper technique. Washing hands for at least 20 seconds with soap, especially after removing gloves and handling possible contaminants, is critical. Additionally, following a surgical procedure, instruments should be cleaned and sterilized according to established protocols for safety and hygiene.
