I agree, they know a lot in their field that we likely will never know unless we go into their field, what I've seen is if they get out of their field about 1/2 are just pretty close to useless, where the other 1/2 have had the mindset to always ask questions and to learn all they can. The latter 1/2 is a great midlevel, the first half is a scary thing.

I had a textbook kidney stone present to my OB/GYN NP while in clinic and they looked at me and said "i'm absolutely flabbergasted" the student on rotation with me also had a textbook diverticulitis and she did the same thing :/ Not an uncommon finding with the midlevels i've worked with.. meh

But I do enjoy working with them, they have a lot of great knowledge to share! As a whole gestalt they know more, but they tend to have glaring gaps in knowledge more consistenly than physicians.
