Yes, all those history, linguistics, world music, and politics classes I took for my bachelors degree is going to make me a MUCH better nurse. Personally, I'm skipping the BSN because the MSN program in my area allows ADN + non-nursing bachelors to enter straight into the MSN just like a BSN grad would. And several ADN programs in my area have higher pass rates and more clinical hours than the BSN programs.
A lot of the ADN grads, at least recently, are adults with families or career changers who cannot go back and do a 4 year BSN program. It is time consuming and expensive. My ADN program was dirt cheap and I'll have the same job as the BSN grads do and I got my senior preceptorship over a lot of them.
