You are treating a patient who was thrown from his motorcycle after striking a car. Although he initially doesn’t respond when you try to talk to him, when you palpate his abdomen, his eyes open and he tries to move your hand away. He is making sounds, but you can’t discern any specific words. You find that the patient also has abdominal tenderness, several angulated lower extremity injuries, paradoxical chest movement, and diminished right-side breath sounds. What is his Glasgow coma scale?
