Hi! I am currently interviewing for CRNA school and was told to expect questions on Swans cath's for my interview. I am a PICU nurse and have never even seen one @ my hospital, let alone in one of my own patients. As a CRNA, what would you suggest I focus my knowledge on for Swans having never even seen one? What do you think an interview board would expect me to know about one if I've never seen it? I'd really appreciate your help. Feel free to PM. Thanks!
