A nurse is preparing to perform a sterile dressing change. Which of the following actions should the nurse take when setting up the sterile field?

A. Open the outermost flap of the sterile kit toward the body. The outermost flap should always be opened away from the body first to prevent contamination of the sterile field by leaning over it. This helps maintain sterility by minimizing the risk of contact. B. Place the cap from the solution sterile side up on a clean surface. Placing the cap sterile side up prevents the sterile inner surface from touching the contaminated surface and helps maintain aseptic technique during solution use. C. Place the sterile dressing within 1.25 cm (0.5 in) of the edge of the sterile field. The outer 2.5 cm (1 inch) border of a sterile field is considered contaminated. Placing items too close to the edge increases the risk of contamination and compromises the field's sterility. D. Set up the sterile field 5 cm (2 in) below waist level. Any sterile item held or placed below waist level is considered contaminated. The sterile field must always be maintained above waist level to preserve asepsis.
