As a Corpsman in the 1970s, I thought (tongue-in-cheek) that nurses carried narcotic keys and took telephone orders. Corpsman learn alot of how-to stuff. When I went to nursing school having that how-to experience let me relax when others were sweating how to place an IV, put in a foley or any number of other practical skills. But appreciating the nursing process was not something that came with Corpman training. Go to nursing school and enjoy the advantage(s) your prior training will provide.
