What is a Certified Registered Nurse Practitioner (C.R.N.P.)? The C.R.N.P. may practice medicine under physician supervision. Most likely, the nurse practitioner is whom a patient will first see during a medical visit. The nurse practitioner assesses a patient's health status by attaining health histories, performing physical exams and ordering and interpreting diagnostic tests. The nurse practitioner consults with a physician and establishes a health care plan.

What is a Physician Assistant? A physician assistant (PA) is a health care professional licensed to practice medicine with physician supervision and is trained to do many tasks that physicians usually do. As part of their responsibilities, PAs conduct physical exams, diagnose and treat illnesses, order and interpret tests, counsel on preventive health care, and in Pennsylvania can write prescriptions. PAs must complete an accredited, formal education program and pass a certifying exam. Those PAs who pass the exam may use the credential “PA-C.”
