For those who have heard the term but are unfamiliar with the difference between a Nurse and Nurse Practitioner, Nurse Practitioners are registered nurses (RNs), who then obtain a Masters Degree in Nursing, and can, “diagnose, order tests, prescribe drugs and carry out procedures normally restricted to physicians.”
Dalhousie and Ryerson Universites recently released the results of a joint three-year study on the nurse practitioner role and its value to the healthcare system, and summaries of the report can be found here and here.
