Ok...I'm kind of new to this stuff and I was wondering what the "hierarchy" of nurses was. I've heard RN (2 year schooling), BSN, MSN, APN, and DPN.

I'm basically wanting to move up the chain as close to MD as I can without medical school. I thought a masters in nursing as an APN was it, but I just read another thread about DPN (doctorate in nursing I guess)...anyways - just wondering.
