Nurse

Nurses were health care professionals generally subordinate to medical doctors. Some were surgical nurses, who actively assisted surgeons during invasive operations. Others focused on patient care in general hospitals or specialised facilities such as mental institutions and research laboratories. Still others worked in emergency settings, which often required a blend of surgical and patient care. Finally, some worked for private institutions, such as schools or companies.

Occasionally, individuals impersonated nurses, usually to enact a criminal plan or alien invasion.

"Nurse" was also a surname, likely only amongst English-speaking humans.
