What is the primary purpose of keeping the outer border of the sterile field non-sterile?

• A. Contamination of the sterile field.
• B. Faster instrument handling.
• C. Increased visibility of drapes
• D. Reduced need for antiseptic.

Answer: (A)

A non-sterile outer border creates a protective buffer that helps prevent contaminants from reaching the sterile field. By designating the inner area as sterile and treating the border as non-sterile, any potential contact or splash from surrounding surfaces, personnel, or instruments is kept away from the critical zone where the incision will occur. This boundary also provides a clear visual cue for staff to maintain sterility and minimize transfer of contaminants. The other options don’t address the primary purpose: speed of instrument handling, drape visibility, or antiseptic use aren’t the central goal of keeping the border non-sterile.
