Liability issues

If you are not credentialed by an institution as a provider, I don't see how anyone can hold you liable for not writing/changing orders on a patient (which no one can do unless they are credentialed/privileged by the institution) -- and this is really the crux, IMO. Any good RN should question something that is not right - and this includes APRNs who may be working in an RN role (and who will probably have deeper insight into appropriateness of medical orders). So I suppose we can all be held accountable for what we should know - but that has always been the case for every level of licensure.

Now, I have heard that some states forbid APRNS to work in an RN role. I do not know which states these are, but I have heard this, and this is different. In this case, an APRN will not be offered an RN job in the first place (except in the unlikely scenario the hiring organization does not know the law -- so know your state's laws).
