One thing I know for certain and from experience, a chief medical officer who takes every patient for his own will be a hated chief medical officer. Therefor I made a character from a Pharmacy background, with limited knowledge in surgery, virology and genetics; to the point he requires a learned assistant to practice them. Yet, recently in a random thought I asked myself, "What kind of backgrounds would a chief medical officer be allowed to come from?"
I thought on it, thinking that the chief medical officer is to be the public figure of the medical bay, the one who takes responsibility for what happens and what does not, the one who commands his colleagues to do the correct thing at the correct time. This made me think, would nurses be able to be chief medical officers? Some nurses go to school as long as doctors do; I'm honestly surprised they don't have a title like other doctors.
So, here's a question. Are nurses eligible to become a chief medical officer?
And one more. Are auxiliary employees ( people employed through another company, ex. Zeng-Hu ) able to become heads or possibly be employed as a head through their home company?
