Hi Beth, I am in the complete opposite situation! No worries :) I have been a RN for 8 years with ONLY ER experience. I applied to USA for BSN-DNP in Women's Health last year and was accepted. I too had reservations about doing something out of my usual scope of practice, but ended up going for it because I wanted to really specialize in an area. Either way, I think you are fine. Choose what you love to do...because it will be what you do for the rest of your life. Either way, certificates in FNP or WHNP can be earned. I hope this helps!
