An emergency room physician is using a defibrillator to save a patient’s life. Which step should she take to protect her own safety and the safety of others in the emergency room?

A defibrillator sends an electrical shock through the patient, so anyone touching the patient could also be shocked. The physician should make sure everyone is clear and no one is touching the patient before delivering the shock. Therefore, the correct choice is “make sure no one is touching the patient when using the defibrillator.”
