Everyone has a point. After my first week of acute care at a county hospital where I have seen more than I have ever seen in my puny life, I can say that after getting to know how things work at the hospital and learning a lot from my CI, there needs to be a collaborative relationship.
Quite a few physicians at the hospital "order" for physical therapy (although, it's technically "consult") when there was no apparent need for PT, and my CI duly told me to use my judgment: read any previous notes, take a look at the history, go over results of any tests, and determine if there is a need for PT. Sometimes, it's the opposite, where physicians actually order PT when PT is contraindicated. In this case, my CI told me again to use my judgment on this whether or not to see the patient.
If we do have reservations about seeing a patient we can always ask for a re-consult when the pt is more stable, and that's that.
Of course, if the physician ordered strict bed rest or restrictions to activity, then obviously we can't do anything with the patient since the physician manages the pt's medical condition, and that's priority.
