Can you be a Nurse Anesthetist with a BS in Physics?

Answer 1

Yes, but it depends. Each state will have its own requirements for what an NA must complete before receiving their certification. You'll likely still need to take additional courses, etc. as well as complete other clinical requirements. So your BS in Physics probably gets you part of the way there, but you'll still have more to do (which would be the case with almost any high-level certification and any degree, even if it's suited for that field).
