Is there anyone out there with CVN certification? I'm interested in obtaining it, but having a difficult time getting some questions answered. I wrote accn twice and they haven't answered me. Do you have to have your BSN to get your CVN? I looked this up and it LOOKS like you can have your ADN, it's just a different level certification. Maybe I'm wrong. Also, is there any study material out there to help prepare for it? Even if you need your BSN for the certification, I'd still like some study materials, as I'm back in school for my BSN anyway. Any help anyone can provide would really be appreciated!! Thanks!
