Pulmonary embolism is a vascular disease that occurs as a complication of venous thrombosis and thrombus rupture, most often from the deep vein area of the lower leg, which ends up in the lungs and clogs the pulmonary arteries or multiple branches of the pulmonary arteries. The tasks of a nurse for a patient with pulmonary embolism are extremely important and demanding due to a number of interventions in health care, namely, the survival rate depends on the prevention and timely recognition and treatment of this life-threatening condition. The aim of the research is to investigate whether there is a difference in knowledge between students of full-time and part-time undergraduate professional study of Nursing on pulmonary embolism, or the clinical part of the disease and the tasks of a nurse / technician in pulmonary embolism. The research is based on an anonymous online questionnaire conducted among first, second and third year students of full-time and part-time undergraduate professional study of Nursing. A total of 100 respondents participated, and the questionnaire consisted of 3 socio-demographic questions and 15 specific questions divided into two categories; the first category of questions consists of eight questions that test knowledge of pulmonary embolism, and the second category of questions consists of seven questions that test knowledge of the tasks of a nurse / technician in pulmonary embolism. The results of the survey questionnaires were statistically processed in Excel. Full-time students achieved 74% of correct answers in the field of pulmonary embolism and 87% of correct answers in the field of tasks of a nurse / technician in patients with pulmonary embolism. Part-time students achieved 80% correct answers in the field of pulmonary embolism and 88% correct answers in the field of tasks of a nurse / technician in patients with pulmonary embolism. There is no significant difference in knowledge about pulmonary embolism, nor about the tasks of a nurse / technician in pulmonary embolism between students of full-time and part-time undergraduate professional study of Nursing.
