Final answer:
The appropriate next step is to sequester and quarantine the monitor, pending referral to hospital risk management.
Step-by-step explanation:
The appropriate next step when an anesthesia provider expresses concern that a faulty monitor may have contributed to an intraoperative death is to sequester and quarantine the monitor, pending referral to hospital risk management.
This ensures that the monitor is no longer in use and prevents any potential harm from occurring to other patients. Calling biomedical engineering to assess the safety of using the monitor for the next case in the room is a good practice, but sequestering and quarantine should be done first to prioritize patient safety.
