I am a CST and I am looking to start nursing school the spring or fall of 2015. I was recently told by someone in administration that once I graduate nursing school I can no longer be hired as a CST. This conversation started because I had a plan of going to a diploma program nursing school, continue working as a CST at my current hospital (because all RN's must have a bachelors degree at this hospital), then get my BSN online. Is it true that once I become an RN, I can no longer go back to being a tech? Will I be forced to work to the highest of my degree?
