I fought this battle before, as I originally was going to school for RT and switched to nursing. I work at a teaching hospital, and because of that, RTs are limited as to what they can do (no intubations, etc). But, they are very busy doing other things such as ER traumas, codes, breathing treatments, etc. I can see where this would be stressful, however, what job in healthcare isn't?
I switched to nursing for a number of reasons, the #1 reason for switching was the variety of work that nurses do. You can work in a hospital, office, school, do case management, etc, and there seems to be much more opportunity for advancement. RNs do earn more than RTs at my facility, but it seems like job prospects are good in both fields.
Good luck in your decision!
I hope this helps!
