Never to late to do what you want. Extra education never hurt anyone, and I'm sure you will find it even lends itself useful as you pursue your NP. Personally, I am just finishing up my 1st year of BS-DNP in Acute Care. Several times I have wondered if I will be limiting my practice as an ACNP, in that I may not be able to work in an ER, urgent care, or primary care as many of the patients are peds and adolescent. My goal is to work in the hospital, however there is definitely no shortage where I am, and wonder if I will be able to find employment as an ACNP. I have decided to stick it out, and if I am unable to get the job I want after graduation, I will return to school for a FNP cert. Best of luck to you.
