The aim of the research was to compare the knowledge of nurses working on standard wards and in departments that provide intensive care. The results were processed in summary Table 1, which contains the basic surveyed areas of nurses’ knowledge of HAI as well as nursing care for CVC. Each area is assessed according to the respondents’ department and to the accuracy of the answers of individual respondents. Those responses that contain all the correct answers are considered “fully answered”. “Partially answered” are respondents’ answers which are not complex, but are true. “Incorrectly answered” are those responses in which any incorrect answer occurs.
