I don't see why getting the x-rays is going to make a difference right now. He's lethargic and not moving anyway, so why not snap a picture and see what's going on? He doesn't need to be sedated if he's as bad as you say.
Why do they need to move him somewhere to continue oxygen? The more he is moved around, the more he will be stressed. I personally would want him to stay on oxygen overnight, not take him off then put him back on.
Renee, he's not going to respond after one dose of antibiotic, but you also need to prepare yourself. He sounds like he's in pretty bad shape. I would go in and hand feed him, if he'll eat, make sure they are keeping him hydrated, give him his stuffy or whatever and spend some time with him.
