Which of the following is a characteristic of a level I trauma center?

A level I trauma center is designed to provide comprehensive care for all injury levels, which includes the capability to manage the most severe and complex trauma cases. These centers are equipped with a full range of services, including 24/7 availability of specialized surgeons and staff across various disciplines, advanced imaging, and critical care services. This ensures that patients with life-threatening injuries receive immediate and appropriate treatment at all times.

The other options do not align with the characteristics of a level I trauma center. For instance, the idea that services are available only during daytime hours contradicts the essential requirement for round-the-clock care at a level I trauma center. Similarly, limiting care to outpatient cases does not reflect the capacity of a level I trauma center, as they are expected to manage both inpatient and outpatient cases, particularly the more severe ones. Lastly, the notion of having limited resources for surgery is inaccurate; level I trauma centers are fully equipped with advanced surgical capabilities and resources necessary to handle a wide range of traumatic injuries effectively.
