Ruth is 20, a plain-speaking Northern lass from Leeds. She's quick-witted; but can be a bit sharp-tongued on occasions. Nevertheless, she's an efficient nurse who maintains a balanced, caring relationship with her patients. Ruth is a keen Union member, and is particularly vocal on the subject of nurses' pay.
Ruth was played by Lesley Dunlop, who's probably best remembered for the long-running comedy series May to December. But 30 years on, she's back to playing a Nurse, Sister Anna Kirkwall in Where the Heart Is.
