I don't think you have a problem, Duane. You gave your word to hospital A and orientation is next week. A man's word is all he's got. There's a saying about looking a gift horse in the mouth, and I can't see a whole hell of a lot of wisdom in burning a bridge before you even get started.
Keep your word. To turn around and dishonor the blessing God handed at that first hospital is likely to set in motion a chain of events that you might just not like so much.
