My MC is going to break her arm skateboarding and seeing as the last time I broke a bone I was three I don't remember what the procedure is once she gets to the hospital. I assume the first thing that would happen is that she would be taken for an x-ray. Once they found out her arm was broken what would happen? Do they get her a cast right then and there? Would she get a room or just be stuck in the ER until her arm is set and she gets to go home?

Also, how many people are allowed various places with her? She is a minor, so I figure at the very least her mom, but I wasn't sure if anyone else would be allowed and at what points.
