Nurse

Nurses were health care professionals. 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.

On Earth, some saw a nurse that was not a woman to be an oddity. (TV: Twice Upon a Time) Infact, among the Doctor's friends were male nurses Rory Williams and Strax. (TV: The Eleventh Hour, A Good Man Goes to War)
