Which action should be taken if a delay occurs after a sterile field is set up?

When a delay occurs after a sterile field has been established, it is essential to maintain sterility to prevent contamination. Covering the sterile field with sterile drapes is the appropriate action because it protects the field from airborne contaminants, dust, and other potential sources of infection. This practice is vital in a perioperative environment, where maintaining a sterile field is crucial for patient safety and preventing surgical site infections.

Taking this action demonstrates adherence to infection control protocols, ensuring that when the procedure resumes, the sterile environment remains uncompromised. This strategy is a standard practice in surgical settings, reflecting the importance of maintaining sterility throughout the entire surgical process, even during unforeseen delays.
