This Korean study replicated a previously published American study. The conceptual framework and method combined ethical enquiry and phenomenology. The research questions were: (1) What is nursing students’ experience of ethical problems involving nursing practice? and, (2) What is nursing students’ experience of using an ethical decision-making model? The participants were 97 senior baccalaureate nursing students, each of whom described one ethical problem and chose to use one of five ethical decision-making models. From 97 ethical problems, five content categories emerged, (...) the largest being health professionals (69%). The basic nature of the ethical problems was the students’ experience of conflict, resolution and rationale. Using an ethical decision-making model helped 94% of the students. A comparison of the Korean and American results yields important implications for nursing ethics education, practice and research. (shrink)
