I think it might be for some. I have a hard time seeing where the differentation of the ARNP role is going to end. If I was 30 yrs younger going in to this I would struggle to decide, I am currently inpatient working at a level one center as a FNP. Sort of grandfathered in, now we hire mostly ACNP's for inpatient. Thing is I take care of kids as well. Both clinic, inpatient and ED/ICU. What cert would be best? I guess ACNP, FNP. Ironically I lecture and precept ACNP and FNP students, and have previously served as expert content source for the initial ACNP workup and planning(though in reality contributed little). My current position needs the pediatric component that the ACNP would not cover. The current consensus model has few advocates, but its water under the bridge and one must live with it.
