Nurse

Nurses were health care professionals generally subordinate to medical doctors. They were roughly divided into two categories. Some were surgical nurses, who actively assisted surgeons during invasive operations. Others were focused more on patient care in general hospitals or specialized facilities such as mental institutions, research laboratories or schools. Occasionally, individuals impersonated nurses, usually to enact a criminal plan or alien invasion.
