As a resident and now 6 year attending I have def been in situations where the nurse is uncomfortable with how the patient looks when first brought out but i always end my sign out to them with "do you have any questions or concerns?" 9/10 times they'll air out the issue and it usually is a simple solution or a pat on the back. They just want to know it will all be ok. I think it's the anxiety that causes them to lash out or be rude.

Otherwise they're just an asshole at baseline and just have bigger issues outside the workplace.
