INTRODUCTION: Triage is defined as the process of determining the patient's treatment priority, based on the severity of clinical pictures, ie his medical condition, and as a process begins immediately after entering the "Unified Emergency Hospital" (OHBP). OHBP is a major position in the health facility for emergency assessment, diagnosis, and treatment of patients. The aim of triage is to identify patients with life-threatening medical conditions and, based on that, to classify the patient in the triage category, which will ensure the level and quality of medical care that is justified by the severity of the medical condition. Triage in OHBP is performed by a triage nurse / technician with many years of experience in OHBP. OBJECTIVE: The aim of this paper is to assess the knowledge of nursing students about the triage process in the Unified Emergency Hospital. METHODS: The research was conducted on undergraduate and part-time students of the undergraduate professional study of nursing at the Faculty of Health Studies in Rijeka for 1, 2 and 3 years. Demographic and clinical data obtained from an anonymous online questionnaire were used to present the results. RESULTS: The results obtained by this research indicate that nursing students at the Faculty of Health Studies in Rijeka have satisfactory knowledge of the triage process in OHBP; 76% of them answered the questions correctly. The results of years of study and learning triage through the above subjects were also obtained, or work in health care does not affect knowledge but the very interest in acquiring knowledge from the profession. CONCLUSION: The triage process itself is very complex and requires careful learning of its guidelines and understanding of the process as a whole. It is the good knowledge of students that will influence later quality health care in professional work.
