Your response shows your own lack of knowledge. It's more complex than "if you stick a needle into something big, it will get a hole". There are acceptable locations to puncture a brachial artery and strict monitoring protocols after brachial artery sticks. Things like artery compliance and pressure aren't as clinically relevant in this scenario, you're just throwing those things out to appear smart. It's not working.
I in no way implied that other healthcare professionals are not intelligent. I do find people that advocate for increased practice rights without a compensatory increase in training to be "stupid" (or ignorant, as
@Matthew9Thirtyfive more properly put it). Nurses are for the most part fantastic when they stay in their role, and are dangerous when they do not. I've seen several nurse-placed brachial artery IVs (even under ultrasound guidance, when they thought it was a vein) and have helped to manage the aftermath. Bad things happen when you just assume that you know what you're doing.
When you operate beyond your level of training, you are dangerous. That could be said of anyone in any training program anywhere. Residents and medical students make blunders as well. The difference is that we're often put in our place by attendings. There simply isn't that kind of oversight and accountability in the NP world, and that is why they turn out overconfident NPs with weak clinical skills.
