A code of ethics provides ethical standards and guidelines to regulate a profession. For nursing, the code outlines moral principles like autonomy, beneficence, and non-maleficence that govern nurses' behaviors and professional actions. It serves to guide ethical decision making, remind nurses of their responsibilities to patients, and inform others about the nursing profession's expectations. The International Council of Nurses first published an international nursing code of ethics in 1953 that has since been revised over time.
