Final answer:
A Level 5 trauma center must have a trauma surgeon available around the clock, specializing in the immediate and ongoing care of patients with acute injuries.
Step-by-step explanation:
A Level 5 trauma center is required to have a trauma surgeon on staff 24x7. Trauma surgeons are specifically trained to provide immediate care to patients suffering from acute injuries. The primary role of a trauma surgeon in a Level 5 trauma center is to lead initial resuscitation and stabilization of patients, and to continue to oversee and coordinate the patient's trauma care. This includes performing surgeries as necessary to treat life-threatening injuries. Other specialists, such as cardiologists, pediatricians, and orthopedic surgeons, may be on call or available on a consultative basis depending on the specific staffing requirements of the trauma center.
