Medical ethics is based on moral principles that guide the practice of medicine. These principles include nonmaleficence (do no harm), beneficence (act in the patient's best interest), autonomy (respect patient choices), fidelity (honor promises and duties), veracity (truthfulness), and confidentiality (protect private discussions). Informed consent and justice in distributing healthcare resources are also important principles. Exceptions to confidentiality include situations involving child or elder abuse, public health dangers, or risk of harm to the patient or others.
