Abstract
Objective: To report the experience of nurses on the knowledge built in a discipline of health technologies, focusing on the light-hard technology of existing guidelines. Experience report: A Brazilian Federal University offers a discipline that discusses health technologies, addressing the existing types, their evaluation and application in the health scenario.

For nurses, the discipline enables new perspectives on daily praxis, as it promotes specific knowledge and provides a critical view of work processes. In addition, the application of knowledge acquired in the discipline encourages the development of guidelines and tools that help in decision-making, qualifying assistance. Guidelines are classified as light-hard technologies based on scientific evidence that provide assistance, education and the empowerment of health professionals. Final considerations: There are different models of guidelines, which are categorized according to content and practical focus, with their applicability being the biggest difference between them. The Care Guidelines has been the most used instrument to promote evidence-based nursing, allowing nurses to implement scientific knowledge in professional care, qualifying it and making it safe.
