Which action best prevents infection during sterile technique?

• A. Touching sterile areas with bare hands.
• B. Maintaining sterile fields.
• C. Reusing contaminated equipment.
• D. Ignoring disinfection.

Answer: (B)

Maintaining sterile fields is essential for preventing infection during sterile technique. The sterile field is a defined area kept free of microorganisms, and protecting it ensures that instruments, solutions, and hands do not introduce pathogens into a wound or sterile site. A breach—such as touching sterile areas with nonsterile hands, reusing contaminated equipment, or failing to disinfect surfaces—compromises this area and increases infection risk. By upholding the sterile field through proper hand hygiene, sterile gloves, and careful handling, you minimize contamination and maximize patient safety.
