Airway first, but if we have multiple residents, the primary one takes the airway, and gives orders, a second will get a central line going (if no IV access) and a third will get the ultrasound and do a FAST exam.
"What do you do first if you suspect the OP has a positive GCS (Generally Comprehensive Stupidity) score:
1. Assure the OP has a patent airway- check to make sure foot is not either directly obstructing the trachea or shoving the tongue backwards
2. Assure the OP is breathing- if still making assinine statements, move on to next step.
3. Determine level of responsiveness- bitch slapping is appropriate, a sternal rub is not.
Ok, ok. I think you got an unfair amount of poop thrown your way. So let me try to give you real answer. TBP and Lattimer were right. Even in a situation where you highly suspect intra abdominal injury you still take care of Airway, Breathing, Circulation, Disability first. Once you have your airway secure, good ventilation, 2 large bore IVs running warm NS boluses and have addressed Ccpine you can eval the belly. First with the exam of your secondary survey, then with ultrasound, CT, DPL or serial HCT and exams. If you identify an actual injury the surgeons decide if it needs acute surgical intervention to fix. That's all if it's a blunt injury. If it's a penetrating injury your secondary will determine if it violates the abd wall. If it does then it goes to the OR.
