It's almost always just LPNs, I personally do not know any RNs on this level of blithering idiocy. The NCLEX exam only requires a little more than 50% correct answers for their exam. And I'm not shitting on nurses, I promise, but I did a "prep" test once to prove a point to someone and I passed it easily, I'm an engineer. I don't know if the standard for testing has always been so low but it is now and it's terrifying to be honest.
