Emergency Nursing is a nursing specialty in which nurses care for patients in the emergency or critical phase of their illness or injury.
While this is common to many nursing specialties, the key difference is that an emergency nurse is skilled at dealing with people in the phase when a diagnosis has not yet been made and the cause of the problem is not known. Emergency nurses also deal with non-emergent populations that present with non-life threatening issues as well.
