You arrive on the scene at an extended care facility where you see the facility employees removing the residents via wheelchairs and hospital beds. As you exit the ambulance, an employee walks up to you and identifies herself as the night-shift charge nurse. She states that the facility had a furnace malfunction and the carbon monoxide alarms are sounding. There are probably 30 residents already in the parking lot a safe distance away, and there are reportedly 15 more inside who are unresponsive. Given the number of patient overall, the EMT should:
A) Alert dispatch of the need for additional resources B) Put on a TB mask and gain entry into the facility to remove the unresponsive patients C) Send his partner into the facility with another employee to start rendering care where the patients are lying D) Continue to supervise the actions of the facility employees until all the residents are removed from the facility
