The Hippocratic Oath is a famous oath made by doctors, setting out the aims of doctors and their moral obligations. The version sworn by nurses, which is still popular in some forms, was named after Florence Nightingale, who definitely embodied it.
I solemnly pledge myself before God and in the presence of this assembly to pass my life in purity and to practise my profession faithfully.
I shall abstain from whatever is deleterious and mischievous, and shall not take or knowingly administer any harmful drug.
I shall do all in my power to maintain and elevate the standard of my profession and will hold in confidence all personal matters committed to my keeping and all family affairs coming to my knowledge in the practice of my calling.
I shall be loyal to my work and devoted towards the welfare of those committed to my care.
Oaths like this are still used, albeit in a modified form, binding nurses to uphold the same principles that Florence Nightingale herself embodied. Not a bad tribute to her!
