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.
