The following are multiple choice questions (with answers) about medical knowledge.   **Question:** An 18-year-old male is brought in by fire rescue. The patient was an unrestrained passenger in a motor vehicle crash and was ejected from the vehicle after collision. Upon arrival to the trauma bay, the patient has a Glasgow coma scale (GCS) of 6. He is rapidly intubated, and vitals are a temperature of 99.5°F (37.5°C), pulse of 130 bpm, and blood pressure of 83/64 mmHg. He is noted to have multiple ecchymoses over his body, as well as petechiae and purpura. He has a laceration over his clavicle that continues to bleed despite a pressure bandage. Radiographs of his lower extremity show multiple long bone fractures. Two large bore IV lines are placed, and the patient oozes from around the sites of venepuncture. Labs are notable for a WBC of 20,000/mm^3, Hb of 10.1g/dL, platelets of 48,000/mm^3, and prolongation of the PT and aPTT. This patient's presentation can best be explained by which of the following diagnoses?   (A) Air embolization   (B) Tension pneumothorax   (C) Disseminated intravascular coagulation   (D) Coagulopathy of trauma
