Emergency Medical Response
You Are the Emergency Medical Responder
Your fire rescue unit responds to the scene of a motor-vehicle collision involving a car with two people and a minivan driven by a woman who has two small children in car seats. As you size-up the scene, three people appear to be injured. The first person, a woman who was driving one of the vehicles, is going in and out of consciousness. You suspect her injuries may include possible fractured ribs. The second person, a passenger in the same vehicle, has injuries on the right side of his body. The third person, the driver of the minivan, appears to have chest and abdominal injuries, but she is conscious and you can speak with her. She is distraught because her children are in the back of the minivan and she is concerned about them.
