Nurse Ratched is the head administrative nurse at the State Hospital, a mental institution 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 psychotherapy, which consists mostly of humiliating patients into doing her bidding.
Remember: FIRST DO NO HARM!!
