The purpose of this study was to examine the moral concerns and problem-solving behavior for outpatient nurses in palliative cancer care. The target of this study was 284 outpatient nurses(22.9%)out of 1,241 respondents. As a result, it was concluded that outpatient nurses providing palliative cancer care have higher ethical concerns than nurses working in acute care hospitals. In addition, the more moral concerns there were, the more nurses manage their care according to patient's individual circumstances. In the future, it is necessary to provide education on the moral concerns of outpatient nurses and the problem-solving behavior for nurses so that patients in the final stages of life and their families can spend a better time.
