Maintaining a sterile field is crucial in medical settings to prevent infections and ensure patient safety. The rationale behind considering a 1-inch border around the edge as non-sterile relates to established guidelines for maintaining sterility. This border serves as a safety margin; it recognizes that even if the outer edges of a sterile field are handled, they can become contaminated through contact with non-sterile surfaces or hands.

Therefore, anything that is placed within this 1-inch border can be assumed to be non-sterile, which helps prevent contamination of the sterile instruments and solutions located in the center of the field. By adhering to this guideline, a Patient Care Technician (PCT) can help ensure that the sterile field remains safe for use during procedures.

The other options lack accuracy in the context of sterile field management. For instance, stating that all areas are sterile as long as they are cleaned ignores the fact that cleaning does not confer sterility. Similarly, the idea that only the middle of the field is sterile neglects the importance of the entire context of the field setup. Lastly, asserting that only instruments need to be sterile overlooks the necessity of maintaining a sterile environment, which includes drapes, gloves, and other surrounding items.
