Ok, now it's easier to answer you since I know where you are.
In Ontario there is the Regulated Heath Professionals Act (RHPA) This is what tells you as a nurse what controlled acts you can perform and what controlled acts a physician or lets say a respiratory therapists can do. You can as a nurse delegate some of your controlled acts to say an RPN. A physician can delegate some of his acts to you if you have the 'knowledge, skill and ability' to do so. This is how I practice, yes I can certainly 'do more'. I have a policy of delegation with the 3 physicians that I work with, that uses medical directives. Is this independent practice? No. But it does cover me and allows me to do just about anything I want in the hospital as long as I can back up my actions with evidence. I am an ACNP. Primary Care NP's however in Ontario practice under a system of incependent practice and medical directives for those things that must be delegated by a physician.
Is this an extended scope of practice over an RN? Absolutely.
If you want more info on this look up the RHPA on the web you can find the full document. Go to the College of Nurses for more info and the NPAO (Nurse Practitioner Association of Ontario) web site at www.npao.org.
(By the way I am the regional rep for NPAO)
As far as school goes to be a Primary Health Care NP (PHCNP) in Ontario at the moment requires a BScN and then a post BScN certificate (I think about 18 months past the BScN) however this may change to a Masters as the entry to practice in the near future. To be an Acute Care NP requires a Masters degree. The only ACNP program in Ontario at the moment is at U of Toronto. Mac and just about any Ontario University that has Nursing has a PHCNP program. You can also look into Athabasca U that has a distance ed Primary Care Masters program.
Hope this helps you understand the system! Feel free to contact me in a private message and I can hook you up with some PHCNP students I know or we can meet for coffee somewhere to go more in depth.
