I believe there is one school in the NE that you get your bsn, work in their hosp a year, then go on to crna school. I have heard that most are unable to get into crna school when they like b/c there are not enough open positions for new grads in the icu's there. Going on to crna is considered ADVANCED practice. Meaning you already have considerable practical experience as a critical care nurse before you enter. They are building on that foundation that you have already received. Please read around in the APN forums here and elsewhere about crna's, their job, their schooling, etc.
