I take issue with that analogy. In a modern hospital, doctors and nurses work together - one can't do their job without the other and they have different training and approaches to patient care. The doctor doesn't simply have a superset of knowledge that encompasses everything a nurse knows or is trained to do. So although there might be some strict hierarchy in terms of who is in charge of patients care, it's simplistic and disrespectful to say doctors are superior to nurses.
