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. Place the cap from the solution sterile side upon a clean surface: The sterile side of the solution cap must be placed on a clean, dry surface to maintain its sterility. This prevents contamination of the solution during use, which is critical for infection control during dressing changes. B. Place the sterile dressing within 1.25 cm (0.5 in) of the edge of the sterile field: The outer 1–2 inches of a sterile field are considered contaminated, so placing items too close to the edge risks contamination. All sterile supplies should be placed well within the sterile field boundaries. C. Set up the sterile field 5 cm (2 in) below waist level: Setting up below waist level increases the risk of contamination from clothing or accidental contact. The sterile field should always be at or above waist level to maintain sterility. D. Open the outermost flap of the sterile kit toward the body:Opening the outer flap toward the body forces the nurse to reach over the sterile field, increasing the chance of contamination. It should be opened away from the body for safety.
