When setting up a sterile field for a dressing change, which action is appropriate?

The appropriate action when setting up a sterile field for a dressing change is to open the first flap on the sterile package away from the body. This is crucial because it helps to maintain sterility by preventing any contaminants from falling into the sterile field. By opening the flap away, the practitioner ensures that they are not reaching over the sterile items, which could introduce microorganisms from their hands, clothing, or body.

Proper technique in opening sterile packages is essential in preventing infection, especially in a clinical setting where the integrity of the sterile field is vital for patient safety. This practice is part of the larger guidelines and protocols associated with infection control and ensuring that any procedures carried out maintain a high standard of cleanliness and sterility.

The other actions mentioned do not align with proper sterile technique: placing instruments directly on the table can lead to contamination, using both hands to open a sterile package could compromise sterility, and turning one's back while preparing the sterile field can invite contamination from unsterile sources.
