Nurses help patients not lose their humanity to the end in the asymmetrical relationship between medical personnel and patients. Because the nurse's frequent judgments at the clinical site are associated with human dignity, the nurse is required to judge and act ethically, and is responsible for making ethical decisions. Therefore, nurses are trained from nursing colleges to have ethical competence, and such training should be carried out continuously and systematically even after graduation. A Medical Center Nursing Department implements various forms of ethical education to improve the ethical capacity of clinical nurses. Education is divided into four types: lectures, e-learning, workshops and clinical ethics counseling. All education was organized around real-life cases to realize that nursing ethics were not far from the actual work site but the closest problem encountered, and the core theories and issues were repeatedly and continuously exposed so that they could permeate into the nurse's ethical decision-making process. Of course, there are still more tasks to be carried out in the future, such as expanding debate-oriented education, promoting clinical ethics counseling, setting up a forum for sharing opinions on ethical issues such as the Ethics Round, but we hope that it will serve as a foundation for the development of better nursing ethics education programs by sharing specific cases of nursing ethics education currently implemented at a tertiary Hospital.
