Final answer:
The nurse should stop the procedure immediately to confirm the correct surgical site before proceeding with the right breast biopsy. The "time out" protocol ensures patient safety by requiring confirmation from the surgical team before incision. Reminders for site marking are important for future procedural compliance.
Step-by-step explanation:
If a patient is scheduled for a right breast biopsy, but no site markings are visible when the patient is draped, the ambulatory care nurse should stop the procedure until the correct site is confirmed. It is critical to patient safety that surgical procedures are done on the correct site, and visible site markings play a crucial role in ensuring this. Ignoring the absence of site markings or assuming the surgeon knows the correct site without confirmation could lead to wrong-site surgery, which is a preventable surgical error.
The nurse should consult with the surgeon, but they must also advocate for patient safety by confirming the correct site, according to the protocol. The "time out" process, which involves the entire surgical team orally confirming the patient's identity, surgical site, and procedure before the skin incision, is designed to prevent errors such as these. Therefore, it would be necessary to make a note to remind staff to mark surgical sites and review this protocol for future procedures to reinforce the importance of compliance with safety protocols.
