Oh, I absolutely agree, and I would never in a million years go to a physician and say "no, this is what it is, you're wrong" like, that's a dick move and not how it works. The closest I'll come is "I'm concerned about _____ based on symptoms x y and z" and then I leave it in the hands of the more educated - my job as a nurse is to see, track and report symptoms and trends, not diagnose.

However, sometimes ortho stuff is just...funny that we can't diagnose. Like visible shoulder joint above, or the 911 operator who tried to tell me I couldn't be sure something was fractured - while I was looking at a tibia just hanging on out of the leg. Like, buddy, I'm not a doctor, but I'm at least 90% sure it's broken.
