A 45-year-old female patient presents to a busy university hospital for an elective carpal tunnel release on her left wrist. During the pre-operative 'time-out' procedure in the operating room, a junior surgical resident, Dr. Chen, who is preparing to assist, confirms the patient's identity and the procedure with the circulating nurse.

The patient is already sedated. This error prompts an immediate halt to the procedure. Which of the following is the most appropriate immediate step in addressing this critical patient safety incident?
