In this study, space is understood to mean the place of insertion or of social action of the nurse, and consequently of the nurse's production in a determined socio-historical situation. We ask the following questions: How are nurses inserted in their professional space? How do they practice their profession? The nursing profession has been looking for its performing space within this context, and it can be seen that its limits are irregular and its frontiers are invaded by other professionals, in the same manner as nurses also go beyond these limits. The reality of the nurse's "space" as it shows itself has been presented and judged, and a presentation is give of what the nurse's space in a praxis perspective.
