I am caught in the same situation, I practiced in Florida as an ARNP with Rx authority because Florida licensing rules recognized my ANCC CNS certification- and with a few additional courses-Health Assessment,and Pharmacology -in my case, I then qualified to apply for the ARNP license. This was all prior to the development of the psych NP cert exam. When I moved to Virginia-which has regs that address transfer of NP licensure-all that changed because I did not have the psych NP cert exam....when I spoke with the BoN...they essentially said, sorry don't blame us..it was your profession that developed the psych NP cert exam!!! Talk about a catch 22!! I wrote to APNA-Anerican Psychiatric Nurse Association-and they agreed this was never the intended outcome and now they are engaged in diaglogue with the State Boards of Nursing-essentially pointing out that the two advanced mental health degrees are the same content...and should be interchangeable. I encourage you to look at their website www.apna.org for the latest information on this.....
It really is outrageous that in this time of acute mental health and professional nursing shortages, that our own colleagues become our biggest detriment to practice...particularly since we have always played a vital role in moving advanced practice forward.
One possible interim move for you would be to partner with a physician for Rx support only. I know that with the shortage of mental health providers here, primary care groups are very interested in partnering...especially in the rural areas. At University of Virginia, there is a telemedicine rural health clinic that provides mental health services throught the dept of psychiatry, and they are recruiting for a clinical specialist to do psy evals, med mgt, etc with the PCP at the rural clinic providing the Rx...and the psychiatry dept has some kind of clinical supervision mechanism in place.....so it is not impossible to negotiate a contract doing everything but writing the prescription.....
I hope other CNSs can give some thoughts and suggestions...I will say however, I have no intention of sitting for a 2nd certification exam ...best to you in your decision making process.....
