Physician Assistant explains career and difference between a PA and a doctor and a PA and a nurse practitioner. Excellent explanation of the career by a knowledgeable physician assistant. This is from an instructor's resource CD for a medical terminology book. If the creator or PA depicted in this video would like this remove please email me and I will do so. I figured this was meant for education and what better way to educate the public than put it on youtube! Thank you. -Chris, PA-S
