Objective: To analyze the knowledge of professionals working in a Nursing Home about the Nursing Process before and after the awareness workshop. Methods: This is strategic action research, developed with nursing professionals and managers of a Nursing Home in Rio Grande do Sul, Brazil. Data were collected between January and June 2023, through semi-structured interviews before and after an awareness workshop. Discursive textual analysis of the data was carried out. Results: The central category “Understanding about the Nursing Process in Nursing Homes” emerged, which was unitized into two units of meaning and three categories of analysis. Conclusion: Data revealed non-use and lack of knowledge of the Nursing Process before awareness raising. Afterwards, a deeper understanding of the topic and its importance was identified. Awareness-raising workshops contribute to transformation of knowledge.
