What is the purpose of performing hand hygiene before an aseptic task?

• A. To prevent contamination of the sterile field.
• B. To remove all germs from skin.
• C. To satisfy policy only.
• D. To improve grip.

Answer: (A)

Hand hygiene before an aseptic task aims to prevent contamination of the sterile field by lowering the microbial load on the hands. Even hands that look clean can carry bacteria, viruses, or spores that could be transferred to sterile instruments, dressings, or the patient’s wound. Washing with soap and water or using an antiseptic hand rub reduces these microorganisms, helping keep the sterile setup uncontaminated and reducing the risk of infection. It’s about safety and infection prevention, not about removing every germ completely, not about policy alone, and not primarily about grip.
