A nurse is preparing to perform a sterile dressing change for a client who has a surgical wound. Which of the following actions should the nurse take to prevent contamination during the dressing change?

Begin the dressing change by applying sterile gloves and removing the existing dressing.

Remove a piece of the new dressing that falls 5 cm (2 in) from the edge of the sterile field during the dressing change.

Place the existing dressing on the outermost portion of the sterile field and discard it.

Restart the procedure if the sterile solution splashes onto the sterile field when pouring the solution into the dressing tray.
