Final answer:
The nurse should only intervene if a practice is observed that could lead to contamination of the sterile field. In the given scenarios, all listed options properly maintain surgical asepsis, so no intervention is necessary.
Step-by-step explanation:
When assessing for aseptic technique in the surgical suite, the nurse should intervene if any practice might lead to contamination and compromise the sterile field. In the scenario provided, the nurse would not need to intervene for options a, b, or d, as they all describe appropriate measures for maintaining surgical asepsis: team members wearing sterile gowns and gloves, masks covering nose and mouth, and instruments on a sterile tray without moisture present. However, any other observation that deviates from the strict protocols required to maintain asepsis should prompt intervention. It's crucial for the surgical team to follow protocols such as proper handwashing, sterile draping, and usage of sterilized equipment to prevent the patient's exposure to potential infections.
The nurse should intervene if a member of the surgical team has their mask covering only their mouth and not their nose (option B). Proper surgical asepsis includes wearing masks that cover both the nose and mouth to prevent the spread of bacteria and other contaminants. Wearing sterile gowns and gloves (option A), organizing surgical instruments on a sterile tray (option C), and covering the surgical table with a sterile drape with no evidence of moisture (option D) are all appropriate measures to maintain surgical asepsis and prevent contamination.
