Still, they are focusing on a generalized idea on the Science of the illness. So by definition, it should be seen as STEM.I personally believe it does not fall under STEM because nurses learn how to treat patients with medications but they do not focus on the science behind the specific illness they are treating. In order for nurses to be under the STEM category, I'd say they need to do research or prolong their studies to a Doctorate Level so that they can research the disease or that particular illness.
