Yeah, this whole discussion cracks me up. I have a number of direct experiences with Kaiser nurses. They repeatedly got into arguments with doctors in front of me, tried to countermand doctors' instructions, ignored their patients, and complained to each other about their patients while they were right there.
Repeated unprofessional behavior with no discernible change after trying to address it. My take is that the Kaiser nursing org has a serious discipline and customer (patient) focus problem.
To one degree or another, this is endemic among nurses. It's part of a broader cultural element: nursing programs have entrenched a culture of nurses vs. doctors. There are literally questions on their licensing exam to the effect of "which of these orders from a doctor should you refuse to enact?" (rather than, say, "which of these orders should you contact the doctor to seek clarification on?" or some other collaborative take). Nurses are taught their job is to protect patients from physicians. Given they don't have the expertise to do that , the general result is more broadly a power struggle in the guise of patient care.
