INTRODUCTION AND OBJECTIVE OF THE RESEARCH. Death and dying are viewed from different points of view and discussed in different fields, and euthanasia is defined as the intentional termination of life of a person suffering from incurable and severe physical pain for the purpose of alleviating and ending suffering. This paper aims to determine the level of knowledge and differences in attitudes about passive euthanasia between full-time and part-time nursing students. MATERIALS AND METHODS. 122 students from all years of undergraduate nursing at the Faculty of Health Studies in Rijeka were surveyed, and the survey was conducted with a knowledge test and a questionnaire on the acceptability of passive euthanasia. THE RESULTS. The results showed that nursing students' knowledge about passive euthanasia is high, and that there is no connection between the level of knowledge and students' attitudes. Depending on the type of study, there is no significant difference in the level of knowledge, nor in attitudes. If we look at the share of positive responses to statements of attitudes, we can conclude that the attitude towards the acceptability of passive euthanasia is positive. CONCLUSION. By using this sample, the views of nursing students who could be directly or indirectly involved in the decision-making process related to passive euthanasia in the future were learned. In addition, the findings of this research could help open academic and public debate on increasingly topical bioethical topics. As it has already been pointed out in some other researches, in the future more focus should be placed on adding qualitative elements to the results that were collected using quantitative methods.
