Working doctor vs. working nurse by Michelle Jia

What I observed that I think could be harmful:
Most of the images of working doctors are male (there appears to be only one female doctor), and the nurses are all female. There also doesn’t seem to be too much diversity in both the nurses and doctors (predominately white).

Why I think this could be harmful, and to whom:
This definitely presents a gender bias towards these two professions, which can be harmful to those of the opposite gender working in either of these professions. There is some sort of built-in traditional stereotype that doctors are men and nurses are women.
