Actually, in the 18th & 19th century, most "nurses" were prostitutes. Who better to take care of men, especially in war, than a women who were not uncomfortable seeing a naked man and caring for the needs of his body. "Ladies" would never deem this a proper vocation...until Florence Nightengale during the Crimean War. Even then, the "new" nurses got no respect because most nurses were still prostitiues who received most of their pay in liquor.
