At a Level IV trauma center, the expected scenario for a patient admitted would be that they have access to a trauma nurse who can diagnose their injuries and provide initial care; however, they may not have comprehensive specialty surgeon coverage available 24/7. If the patient's injuries are beyond what a Level IV facility can handle, they would typically be stabilized and then transferred to a higher-level trauma facility for specialized care.
Therefore, the most appropriate response is: "A trauma nurse is available to diagnose and then the patient is transferred to a higher-level trauma facility."
