Acute care nurse surveyor questions

Is anyone out there a nurse surveyor? I have an interview set up for this position at the end of the week. I applied so long ago that I forgot all about it until the woman called me yesterday to see if I was still interested and to schedule an interview.

What all does this job entail? What sort of questions might I expect during the interview? I understand there will be a lot of travel involved. That isn't really an issue for me since my child is grown. I think one of my biggest concerns is that this is for acute care facilities and I have been out of the hospital setting for about five years now.

Any information and/or tips would be greatly appreciated.

Thanks!
