Anyway, where I was going with that before A Taco Bell run interrupted it

was that as practitioners licensed nurses somewhere must use something to extend their knowledge out past the limits of the "required reading". Critical thinking comes from a variety of sources by definition. It would seem to follow that the greater the variety of sources, the greater the critical thinking skills.
For a group that uses that phrase so often it is strangely silent on the subject of extracurricular learning.
You however, were kind enough to answer my post and I do appreciate it.
