The leadership role for a nurse leading a trauma team requires the nurse to oversee the trauma team resuscitation in conjunction with the medical team leader. It is important that they work together to ensure the smooth running of both the medical and team elements of the resuscitation effort. The concept of overseeing the team enables the nurse to compile a well structured team which is known to work more effectively (Cooper and Wakelam, 1999). The culture of the trauma…
