Rlianne, I agree that the scope and standards of your certifying body in concert with your board's rules and state law would dictate what you can/cannot do. It is a very gray area, and very state-dependent.
Quote from HollowayNP
I was a ACNP for over 4 years working in family practice (seeing 13 year old and up). I have since obtained my Post MSN FNP certificate. Before I ever started my position in family practice, I spoke and emailed my state BON to clarify what I was and wasn't able to do as a ACNP in family practice. Some states are more black and white while TN is very gray in that area. I was told whatever I learned in my MSN program, I was able to do in practice. I would contact your BON to be sure.
This is the difficulty with the varying quality/scope of NP programs and with the wide variations in state rules... I would think that in an ACNP program, there are far more conditions in your scope of practice than what you truly can be prepared to manage in school... there ends up being a lot of on-the-job, real-world training that needs to take place, and this is true whether you're an RN, NP, MD, PA, RT, PT.
"Whatever I learned in my MSN program" is also not always true. As a psych NP, I had to take one of the three semesters of primary care theory/clinical that the FNP students did... but according to ANCC standards of practice, it is NOT in my scope of practice to prescribe or diagnose anything that isn't psychiatric. Even though as a student I diagnosed/treated more people with bronchitis, scabies, ringworm, and ear and sinus infections than you can shake a stick at. Still... some psych NPs manage hypothyroidism... and some prescribe metformin to try to ward off metabolic syndrome caused by antipsychotics... etc., etc.
