The woman told Mark Wright, 39, that he had "no (expletive deleted) right" to complain that he and other patients had been left lying in their own urine for hours, The Daily Mail reported.
Wright admitted himself to the hospital after suffering severe chest pains that were later attributed to stress.
The woman was reprimanded for swearing at Wright, but the next day she went right back to swearing at him.
"She just started screaming at me, effing and blinding. She said 'you've got no (expletive deleted) right talking like that, no (expletive deleted) right to be complaining,'" he said. "She said she was going to retire in a few days, and the complaint would affect her pension."
The nurse was later forced to resign, and it was not known whether she received her pension.
