are different in their requirements. And I can only go by what I know here in New Orleans. I went to an ASN (ADN) program to obtain my RN. It is my understanding that to complete the BSN through LSU (Louisiana State University) and Southeastern requires only classes that can be completed online.
An ADN-RN does the same job and has the same scope of practice as a BSN-RN. However, going with the mindset that education is a good thing, most places want a BSN, and a few hospitals require it.
Another thing to keep in mind is that every so often, there is a push by the NLN to require RN's to have a BSN and that ADN RN's be grandfathered in, with a requirement to complete a BSN within X years or revert back to an LPN. So far, it has always been shot down. I wouldn't be surprised, with the emphesis on education in nursing, to see it pass.
I personally know people that have an ADN-RN and been nurses for 20 years and are as good, or better as some MSN nurses.
