She was struck off the nursing register after the 12 allegations against her were all proved. A hearing at the Nursing and Midwifery Council took this action. She said that she was too ill to attend the hearing.
She was accused of drawing a face on a patient's hernia, making racist remarks about Filipino nurses and for putting a patient's glass eye into a cup of cola as a joke. All the allegations were made during the time period between late 2001 and early 2004.
All her actions came to light in February 2004 when Denise Lake a healthcare assistant made a complaint about Mitchelson.
The council's conduct and competence committee chairman Val Morrison said that she would undermine public confidence and trust in the profession.
She was accused of compromising the dignity of her patients and incorrectly administering drugs. She was also said to have man handled five patients by pushing them on to a bed or chair and in one case slapping one patient on the head.
She was also blamed for being dishonest in recording temperature and blood pressure readings on patients' charts.
