Over the years I've noticed that once someone starts listing off all the procedures, details, and things they know, they probably don't know as much as a nurse.
Maybe it's confidence or a certain smugness, but I'm a RN. If you are a RN, you won't see any need to question the depth of what I know, nor I you. We each know that a nurse doesn't just know how to do things, it goes much deeper than that.
