This study was carried out in a university hospital in Rio de Janeiro. Its objectives were to identify the ways of learning in the practice of the attending nurse in the hospital organization. The theoretical support was based on the light of Shön, Perrenoud, and Benner. This is a case study with a qualitative approach, developed with a semi-structured interview and a focal group. The content analysis was done. The results suggest that in the hospital we find two learning modalities: learning that uses transformation elements and the one that uses the reproduction. We notice that nurses alternate these models taking as a starting point the following variables: how long they have been working in this field, the work atmosphere and the personal identity.
