The actual established doctors, if they're not married already (rare) are typically smart enough to not do that shit at the hospital they're at. Typically.
It does take a lot of work, but holy fuck does it not take a lot of intelligence to become an RN. I'm not in any fashion accusing all RNs of being stupid; anyone that works at a hospital too will understand that. But goddamn, sometimes an RN will come along that makes one think, "I do remember nursing school being easy as fuck, but apparently that's not because I'm a genius."
