As a disaster nurse, you aid in a crisis relief effort through an organization. You work with an emergency response team, and your duties revolve around providing medical care and attention to victims of a disaster. You treat one patient at a time, tending to their wounds or ensuring they are injury-free. Your responsibilities vary by the crisis, but you typically administer IVs and assist doctors in emergency operations. You also help other nurses with their duties and provide them with a much-needed break while you take over their job. You may respond to natural or man-made disasters.
