what are the benefits or differences in 2yr nursing and 4yr

I think you can probably work in any department with a 2 year RN. It may depend on the facility and the state. I have to say it seems like getting hired is easier with a 4 year degree. It is also a suggested standard for RN licensure that may be implemented in the near future. I am sure those already licensed will be grandfathered in.
As for the benefits or differences, it seems to me (I started out at a 2 year program and switched) that in a 2 year program you have almost the same courses it's just many are prerequisites for getting into the program. When I transferred I had not taken any "nursing" courses but there were a good number of classes my fellow BSN students were taking as part of the program that I had already completed as prereqs.
I think it is worth it if you can to get the BSN. I know many that are now working to "upgrade" for a variety of reasons.
What are other peoples experiences? Any places hire only BSN?

One difference I heard was that a BSN makes it easier to go into management.

This topic has been addressed quite a few times in previous threads, I recommend doing a search.....

I know some hospitals require the RN to work regular or special care nursery before NICU, but the type of degree does not seem to be an issue just yet. The big difference, to me, is that ADN RN's have not had time to "become" a nurse and have a little more adjustment that BSN. But it usually depends on the individual.

Huh? Are you saying that being in school longer is how someone becomes a nurse? And that a 2yr degree needs more time to adjust to the real world of nursing because all they've done is nursing theory and clinical rotations? Just want to be sure I understand the logic behind your statement....

ADNs take the same NCLEX BSNs take. We have a mix on our unit (PICU).

I am not going to debate this issue, it's an old one with its own forum.

It will cost you an extra $20,000-$30,000 then you can make an extra dollar an hour for your BSN. I have worked in education and management all with an ADN. I am making close to 6 figures in the NICU with my RNC. If you have the opportunity, time and money absolutely go for the BSN.
