You can work pretty much anywhere you like, except management (in most places). I only have an ADN, and I have worked peds, pediatric ICU, pedi sub-acute, adult sub-acute, acute rehab, hospice, pediatric emergent care, prison nursing, and geriatric psych. I got my certification in generalist pediatric nursing back in 1996. No one has ever told me I should get a higher degree. Of course, I want the BSN, and I'm almost done with my prereqs for the BSN at my chosen university. But the truth is, nurses are needed so badly that the degree doesn't matter (currently). Of course, that can change. A Bachelor's Degree in any field is always an asset, so if you have the money and the opportunity, by all means take it! Best of luck.
