I have experienced the same confusion. Creighton does have a two week course, which I am headed for soon myself, but you don't just pass the National Registry Test and then go get a Ks License. You have to finish FI in Kansas, and then if you pass National Registry you get a Nebraska License and transfer it to Kansas. Your scope of practice as an RN on an ambulance depends on your services medical director. Get him/her to write standing orders for you instead of protocols. Then you can essentially function as a nurse on a truck, or at least with in the scope of whatever your medical director writes for you to practice. Good luck.
