In nursing, the four cardinal principles, often referred to as the "Four Rules of Nursing are beneficence, nonmaleficence, autonomy, and justice. The principle of beneficence entails that physicians have a duty to behave in the best interest of their patients. This principle upholds many moral guidelines aimed at safeguarding and advocating for the rights of others, preventing injury, eliminating conditions that may lead to harm, assisting individuals with disabilities, and rescuing those in peril. Nonmaleficence refers to the ethical duty of a physician to refrain from causing damage to their patient. This principle, when expressed succinctly, upholds multiple moral guidelines - refrain from taking lives, refrain from inflicting pain or suffering, refrain from disabling others, refrain from causing offense, and refrain from depriving others of life's necessities. According to Nursing Assignment Services, the rationale behind autonomy is rooted in the belief that every individual possesses inherent and absolute value, and as a result, should possess the ability to make logical decisions and ethical choices, while being granted the opportunity to exercise their capacity for self-governance. Justice is commonly seen as the just, impartial, and suitable treatment of individuals.
