Under which condition does a sterile field remain sterile?

A sterile field remains sterile when sterile items are placed at least 2 inches from the edge of the field. This principle is essential because the edges of a sterile field are considered non-sterile due to the potential for contamination from the surrounding environment. When items are positioned within this safe zone, they are protected from contamination that could occur if they were too close to the edge.

The practice of maintaining a minimum distance helps to prevent the transfer of bacteria and germs which could compromise the sterility of the items in the field. It ensures that any accidental touch or splash from non-sterile areas does not contaminate sterile items that are crucial during medical procedures.

While covering the field with a sterile cloth can help maintain sterility, it does not address the critical distance needed to ensure that items remain safe from contamination from potential non-sterile surfaces. Wearing gloves is important for maintaining personal hygiene and protecting the patient, but it does not ensure that the field itself remains free of contamination. Lastly, wrapping all items in plastic does not circumvent the risk posed by the edges of the field, as items could still be promoted to contamination if they are positioned too close. Thus, maintaining a distance of 2 inches from the edge is the key factor in sustaining
