How to disagree

If you practice for a length of time you’re gonna come into a situation where you’re going to disagree with your supervising physician regarding clinical decisions,. This can be tricky, morally, and ethically and professionally. I think every situation is a different, but I typically try to protect myself legally as well as the supervising physician , While also doing what’s right for the patient. How do you guys handle this with a patient? Do you tell the patient you disagree with your supervising physician? Do you document that you suggested alternative plan? I want to protect myself while not throwing anyone under the bus.
