Her primary survey was initially intact, but shortly after the secondary survey, her blood pressure drops to 62/30 mmHg. Intravenous (IV) access is obtained, and a massive transfusion protocol is initiated. Focused assessment with Sonography in Trauma (FAST) examination is positive, and the patient is taken to the operating room where a grade IV liver laceration is identified and repaired.
