Answer:
At the beginning, being a nurse used to be considered a synonym of being a witch. Taking care of the sick was just an activity that men could carry out and in case women performed it was just because it was thought to be a religious vocation.
During the Crimean War, Florence Nightingale developed the pillars of what we still use nowadays in nursing. Later, when nursing migrated to the U.S some more people became founders of this practice, such as Lilian Ward, Mary Brewster and Lina Rogers. Ward and Brewster created a house to provide the poor with medical care in Manhattan. Obviously the way to provide this medical care has changed during all these years taking into account the materials that are used such as latex instead of leather and giving the chance to our new generations of nurses to attend specialized schools in order to receive a degree.
Because the doctor is concerned about something the person has.
