Where is the sterile field established relative to the drapes?

• A. Within the drapes that create the sterile field; the outer edges of the drapes are considered non-sterile.
• B. Outside the drapes; the drapes' inner surfaces are non-sterile.
• C. On top of the drapes using adhesive barriers.
• D. Only within the surgical team's gloves.

Answer: (A)

The boundary of a sterile field is defined by the drapes themselves. The sterile field is established inside the draped area, using the inner surfaces of the drapes that face the wound and instruments. Everything placed within this draped zone, including the instruments and the wound site, remains sterile. The outer edges of the drapes are considered non-sterile because they are exposed to the environment and potential contaminants. Adhesive barriers might be used to secure drapes, but they don’t redefine the sterile boundary. The field isn’t limited to the gloves alone; sterile gloves are used to handle items within the field, but the sterile field includes the draped area and the items within it.
