A nurse is preparing a sterile field to perform a dressing change of a client's leg wound. Which of the following actions should the nurse take?

A. Holding the irrigation solution bottle 5 cm (2 in) above the sterile container is incorrect because the solution should be poured into a sterile container without contaminating the sterile field. The nurse should pour the solution from a height that avoids splashing and contamination. B. Opening the outer wrapper of the sterile package toward her body is incorrect. The outer wrapper of a sterile package should be opened away from the body to avoid contamination of the sterile field. C. Placing the irrigation solution bottle cap on the sterile field is incorrect. The cap should not be placed on the sterile field, as it may introduce contaminants. D. Placing sterile objects at least 2.5 cm (1 in) from the edge of the sterile field is correct. This practice maintains the sterility of the field by preventing contamination from external sources.
