I'm including a scene near the beginning of my novel that involves a small car accident. The character was not the driver, but in the accident, she received a concussion, though little else in the way of injuries. Honestly, the concussion is my goal; anything else injury-related is just going to be what turns out the most normal or logical for that situation. The trouble is, my google research on the subject isn't turning out very well because I can't quite figure out how to word my questions correctly to turn up the right results.
So, my question is this: What are the basic hospital procedures for dealing with concussions in car accident victims? I've figured out that she'll most likely be riding to the hospital in the ambulance, but I don't know much of anything beyond that. Like, how long does someone in her situation remain in the hospital? What medications and such would she be given? What tests and such would need to be run? I literally don't know much at all about what happens from when they arrive on the scene to when she is released from the hospital. It's a blank for me, and my google research has been frustrating me about the subject, so I figured it would be better to ask people, instead.
