A 24-year-old man is brought into the ED after failing off his motorcycle. He was not wearing a crash helmet. The EMT-P tells you he was conscious for a time after the injury but then became unarousable. He has an obvious fracture of his left femur and marked bruising over his pelvis. His blood pressure is 100/60 mmHg with a pulse rate of 96/minute. What are the key points in the patient's initial evaluation and management that would be undertaken before embarking on any investigations? What would be the most useful diagnostic tests (refer back to you earlier module) for this patient and how would they be prioritized?
