Most hospitals require an RN... but there are some that hire LVN'S (they call them LPN's in my state). Why don't you look at a few local hospital websites. Look at their employment opportunities and what the position requires. Few hire LVN's/LPN's in my state at least. I only know on one. I've seen your post about how you want to work w/ babies and I'll tell you that it's usually pretty difficult to get a position like that (labor and delivery or mother baby) as a new graduate with an RN... let alone an LPN/LVN. Pediatrics might be easier to get. But $30,000 is an aweful lot of money. Dear God are those your only options? There isn't a cheaper program for an RN? I wouldn't pay that much!
Seriously... you should look at websites to hospitals you want to work at. Your answer will be right there.
