Which statement best describes sterile field integrity and how it is maintained during procedures?

• A. Aimed area kept free of all microorganisms; maintained by sterile technique, proper hand hygiene, and avoiding contamination.
• B. Aimed area kept free of all microorganisms; maintained by sterile technique alone.
• C. A sterile field is reusable after cleaning.
• D. Sterile field requires no ongoing monitoring.

Answer: (B)

Maintaining a sterile field hinges on preventing any microorganisms from entering the area where a procedure takes place. The way this integrity is preserved is through sterile technique, which provides the whole framework for aseptic practice: proper hand hygiene, sterile gloves and instruments, sterile barriers, and careful handling to avoid contamination. The idea that this field is kept free of microorganisms by sterile technique alone captures that all preventive actions to preserve sterility are encompassed within sterile technique.

In practice, you establish the sterile field with sterile supplies and maintain it by continually applying those aseptic practices and vigilantly watching for any break in sterility. The other statements don’t fit because a sterile field isn’t something you simply reuse after cleaning, and ongoing monitoring is necessary to ensure the field remains sterile throughout the procedure.
