During the initial management of this patient, which of the following is most likely to improve the chances for limb salvage? a. Applying skeletal traction. b. Administering anticoagulant drugs. c. Administering thrombolytic therapy. d. Perform right lower extremity fasciotomy. e. Immediately transferring the patient to a trauma center. 11. A patient arrives in the emergency department after being beaten about the head and face with a wooden club. He is comatose and has a palpable depressed skull fracture.

The most appropriate step after providing supplemental oxygen and elevating his jaw is to: a. request a CT scan. b. insert a gastric tube. c. suction the oropharynx. d. obtain a lateral cervical spine x­ray. e. ventilate the patient with a bag­mask. 12. A 64­year­old man, involved in a high­speed car crash, is resuscitated initially in a small hospital with limited resources. He has a closed head injury with a GCS Score of 13. He has a widened mediastinum on chest x­ray with fractures of left ribs 2 through 4, but no pneumothorax. After infusing 2 liters of crystalloid solution, his blood pressure is 100/74 mm Hg, heart rate is 110 beats per minute, and respiratory rate is 18 breaths per minute.
