A sterile field is defined as what?

• A. An area free of microorganisms maintained through sterile technique.
• B. A region where all instruments are sanitized with soap and water.
• C. A field where staff wear gloves only.
• D. A space used for non-sterile procedures.

Answer: (A)

A sterile field is an area kept free of microorganisms through strict sterile technique. This means everything entering the field—drapes, instruments, solutions, and even the personnel’s actions—is handled in a way that preserves sterility. The goal is to prevent any contamination that could lead to infection during invasive procedures. Sterile fields are created with sterile drapes and sterile items, and they must be protected from non-sterile contact and breaches in technique, such as touching non-sterile surfaces or reaching over the field.

Sanitizing instruments with soap and water reduces surface dirt and microbes but does not guarantee sterility of the field. A sterile field requires validated sterilization of items and careful aseptic handling. Wearing gloves alone helps with cleanliness but does not establish or guarantee a sterile environment without the broader sterile technique. A space intended for non-sterile procedures cannot be a sterile field.
