The aim of our research was to determine the demographic profile of health workers (gender, age, length of service and level of education), and then to assess the essential education for elementary activities of nurses in the treatment and care of patients with pulmonary embolism. Venous thromboembolism (VTE) is a term that encompasses deep vein thrombosis (DVT) and pulmonary embolism (PE). Based on the results of current studies, the level of knowledge about thromboprophylaxis among nurses varies and depends on education, years of work experience, continuing education and job. The study was conducted in KBC Zvezdara in the period from September 25, 2021. to 01.10.2021. years. A descriptive study was conducted where a specially designed Survey was used as a research instrument. The questionnaire was filled out by 20 nurses. The group of respondents was mostly female (16), aged between 20-30, most respondents had completed high school and most respondents had been employed for more than 5 years. 75% of respondents said that thromboembolism is very common, 95% of respondents said that the use of oxygen is a mandatory therapeutic procedure, 85% of respondents said that hemodynamically unstable patients need to start thrombolytic therapy with streptokinase immediately, and 90% of respondents answered that maintaining airway patency and monitoring the pulse is very important in patients with pulmonary thromboembolism. The largest number of respondents (90%) answered that they measure vital parameters in patients with thromboembolism every hour. All respondents (100%) answered that monitoring the intake and excretion of food and fluids is necessary, and a total of 85% of respondents stated that physical activity and regular movement while avoiding prolonged sitting or lying down is one of the methods to prevent thromboembolism. Managing VTE, which offers nurses the opportunity to provide intensive care, is an essential professional competence of licensed nurses. It is necessary to improve the continuous education of nurses and encourage nurses to be educated at higher levels of academic education
