The context:

Nurse Mildred Ratched (possibly a play on the word 'wretched') is a fictional character from Ken Kesey's 1962 novel "One Flew Over the Cuckoo's Nest". She was portrayed by Louise Fletcher in the 1975 film version in an Academy Award-winning role.

A cold, sadistic tyrant obsessed with her own power, Nurse Ratched has become synonymous with the stereotype of the nurse as a "battleaxe." She has also become a popular metaphor for the corrupting influence of power and authority in bureaucracies such as the mental institution in which the novel is set.

Nurse Mildred Ratched is the head administrative nurse at the Salem, Oregon State (Mental) Hospital, where she exercises near-absolute power over the patients' access to medications, privileges, and basic necessities such as food and toiletries. She capriciously revokes these privileges whenever a patient displeases her. Her superiors turn blind eyes because she maintains order, keeping the patients from {acting out} (either through antipsychotic and anticonvulsant drugs or her own brand of "therapy", which consists mostly of humiliating patients into doing her bidding). Her greatest success is with the stuttering, suicidal Billy Bibbit, who is so terrified of her that he does whatever she says.
