A Designated Educational Unit certainly sounds like a great idea. During my PN and ASN programs, many students talked of a similar method. Particularly, the LPN-ASN students, having already been through nursing school once, especially pushed for the DEU ideas! We felt the "traditional students" (ie: students who had no previous nursing or medical licensure/endorsement) were missing out on what real nursing was about.
When my friends first started their careers, many went through a period of shock. They had difficulty adjusting to the school model of one patient at a time to suddenly caring for 5-30 patients at once (depending on the facility they were hired at). I was lucky since I still got to focus mostly on one person at a time in a clinic setting and later transitioned to the ER.
I love precepting nursing students and always welcome the opportunity take one under my wing to educate on things like, "this is why we dilute this med, why we use this size of angiocath, and what I expect the doctor to order", but so many of the local 4 year schools have adamant rules against ASN RNs precepting BSN students despite my willingness, experience, and foundational knowledge of emergency care. Just more incentive to get that BSN sooner.
