The aim of this paper is to determine the importance of the nurse in the assessment, prevention, treatment and education of patients with decubitus ulcers. The pressure on the thin layer of skin between the bone protrusions and the hard surface, which is higher than 25 mmHg, and which lasts longer than 2 hours, causes ischemia of local tissue (interruption of capillary circulation), and it eventually leads to permanent deterioration of soft tissue cells. Nursing care for patients with pressure ulcers or risk factors for the development of pressure ulcers is focused on all existing preventive measures that prevent, delay or slow down the onset of the disease. The initial assessment performed by the nurse must include a complete medical history, environmental assessment, and family assessment. The education of medical staff and patients must be an integral part of any preventive strategy against the development of pressure ulcers. The ultimate goal of education is to reduce the occurrence of pressure ulcers. In the research, we applied the survey method using the Questionnaire with 17 questions. We used the Norton scale to assess the risk of pressure ulcers. In a study of patients with pressure ulcers in our study, we concluded that the subjects were older, mostly over 70 years of age, and male was more prevalent. Other data (education, housing conditions, marital status, length of treatment and method of treatment, mobility, physical activity and mental status, risk factors and complications) of our study on 30 respondents agree with data from the world literature. In terms of satisfaction with health services and the work of nurses, respondents are mostly satisfied. The education of medical staff and patients must be an integral part of any preventive strategy against the development of pressure ulcers. The ultimate goal of education is to reduce the occurrence of pressure ulcers.
