It would help to know what class this is for, and what level of first aid training is assumed. Like, is this a quiz question for a First Aid class, or a question for a high school biology or health class? A question for a Boy Scout merit badge test, etc.?
There is also an overly simplistic nature to the question, so it's not from an advanced test or class. Quiz Question -- why is saying that there is no major internal bleeding not consistent with the MOI (mechanism of injury)?
If this is for a simple health class in high school or similar, just go back to the ABCs in detail, and check them out in order (there's a reason they are in that order in the context of First Aid). Airway and breathing are just parts of the total ABC exam and treatment...
Also, related to the MOI, since there are small holes on each side of the body, what do you think caused them? Are they related? If so, how? And based on your answers to that, what do you think some of this person's biggest issues are going to be, and how would you treat them?
