Step-by-step explanation:
The true statement concerning trauma centers in the US is: Level 1 trauma centers have a full range of specialists and equipment available 24/7 and must admit a minimum volume of severely injured patients annually.
Level 1 trauma centers provide the highest level of surgical care to trauma patients. They are capable of providing total care for every aspect of injury from prevention through rehabilitation. A Level 1 trauma center has a comprehensive range of specialists and equipment available around the clock and is also involved in research and education.
Level 2 trauma centers are capable of providing initial definitive care, regardless of the severity of injury, but they are not required to have the full range of specialists in-house 24/7 as Level 1 centers do. Level 3 trauma centers are equipped to provide prompt assessment, resuscitation, emergency operations, and stabilization of injured patients and also to transfer them to a facility that can provide definitive trauma care if needed.
Level 4 trauma centers provide advanced trauma life support before transferring patients to a higher-level trauma center. They may not require having specialists on-site 24/7 but must have the necessary equipment and personnel available to stabilize patients and provide emergency care.
