Which of the following practices is essential for infection control in surgical environments?

The use of sterile instruments is essential for infection control in surgical environments because sterile instruments are critical for preventing the introduction of pathogens into sterile tissues during surgical procedures. Sterility ensures that the instruments do not harbor microorganisms that could lead to postoperative infections.

In surgical settings, the introduction of bacteria or any other pathogens can have severe consequences, including surgical site infections, which can complicate recovery and lead to longer hospital stays or additional surgeries. Therefore, maintaining a sterile field with the use of properly sterilized instruments is a cornerstone of aseptic technique and infection control in these environments.

Other practices mentioned, such as packing wounds with gauze, may be relevant at certain stages of care but do not directly relate to maintaining a sterile environment during surgical procedures. Similarly, wearing makeup during surgery is inappropriate as it can introduce potential contaminants and compromise the sterile conditions required. Feeding patients prior to surgery involves considerations of aspiration risk and dietary restrictions but does not directly influence infection control in the surgical setting.
