Abstract
Objective: To describe the actions performed by nurses and understand their perceptions of autonomy in primary health care (PHC). Method: A qualitative, exploratory, multiple-case study was conducted with seven nurses from Basic Health Units, both with and without the Family Health Strategy, in Goiânia, Brazil. Online interviews were conducted between January and June 2021, transcribed, and analyzed by four researchers using content analysis. Results: A total of 55 actions performed by nurses were mapped and grouped into three categories: individual care, collective activities, and management actions. Two analytical categories reflected professional autonomy: “Working Conditions of Nurses in PHC” and “Professional Practice of Nurses in PHC.” Conclusion: Nurses’ autonomy is shaped by the organization of work processes and the availability of human, material, physical, and informational resources. The scope of practice, clarity of roles, and institutional boundaries determine the realization of professional practice.
