you'll do fine. dress business casual as you would for any professional interview. no one has to teach you how to be a nurse. you got that down. the prison/jail is what you'll be learning. i read a book when i started corrections. i forget the name, but it was written by an inmate, a commander and a prison english teacher. oh, it was "Games criminals play and how you can benefit by knowing them" something like that. it may not be in print, i bought it off amazon.com. maybe someone here knows what i mean. the best advice i can give you is "your patients, they are all liers, watch your back" it's like being a lion tamer in a circus. they are never really tame. if your assesssment skills weren't sharp before, they will be now.
