Which step involves covering or draping the sterile field with a sterile cloth?

• A. Cover or drape the sterile field with a sterile cloth
• B. Open sterile packets and drop sterile instruments on the field without contaminating them
• C. Push the Mayo stand to the side out of traffic
• D. Gather any necessary equipment or supplies

Answer: (A)

Draping the sterile field with a sterile cloth creates the sterile barrier that protects the operative area from contamination. This step is done after the field is prepared and before instruments and supplies are brought in, ensuring the area remains sterile throughout the procedure. The sterile cloth serves as a protective layer between nonsterile surfaces and the items used on the field, reducing the risk of introducing bacteria. While opening sterile packets and placing instruments, if done correctly, supports asepsis, it’s about maintaining sterility rather than establishing the barrier itself. Pushing the Mayo stand to the side and gathering equipment are important prep actions, but they do not accomplish covering the field with a sterile drape.
