Final answer:
To maintain aseptic technique, a wrapper used as a sterile field must extend at least one inch over the edge of the table to ensure that the area is free from contamination and to prevent sepsis.
Step-by-step explanation:
When creating a sterile field using a wrapper, it is critical to ensure that the wrapper extends over the edge of the table to prevent contamination. The recommendation for the extension over the edge of the table is at least one inch.
This margin is necessary to maintain the aseptic technique and ensure that the area remains free of all vegetative microbes, endospores, and viruses, thus supporting the prevention of sepsis. It's important that medical personnel adhere to this standard to maintain the integrity of the sterile field specified area during medical procedures.
