how do you become an anesthesiologist? a nurse anestheist?

An anesthesiologist is a physician. They go to medical school.

A certified registered nurse anesthesist (CRNA) is an advanced practice RN. The requirements vary but one has to have a BSN and usually two years of Critical Care nursing experience to apply to CRNA school. They are the highest paid nurses, and thus the schools are highly competetive to get into.

Good luck.
