O estudo teve o objetivo de refletir acerca da Enfermagem como profissão da saúde à luz da teorização de Eliot Freidson para as profissões. Abordaram-se as credenciais para uma ocupação ser reconhecida como profissão, relacionando-as com as características da enfermagem, especialmente no Brasil. Na abordagem freidsoniana destacam-se como credenciais de profissão a expertise, a autonomia e a autorregulação. A enfermagem é analisada enfatizando a sua responsabilidade por uma gama de fazeres realizados com base em conhecimentos científicos, a necessidade de formação específica para o exercício da profissão, a disponibilidade de saberes e o reconhecimento do Estado do credenciamento formal de proteção aos membros da profissão. Conclui-se que a enfermagem é uma profissão da saúde, com papel fundamental para a transformação da realidade da saúde e que necessita investir no convencimento da sociedade acerca de sua utilidade enquanto profissão voltada às necessidades de saúde das pessoas.

Objective: to analyze night admission characteristics at a Psychosocial Care Center III (CAPS III - Centro de Atenção Psicossocial). Method: a qualitative research, whose data were collected with 15 nursing professionals from November to April 2016, through a semi-structured interview. Results: it was verified that night admission is provided by the nursing team in different dynamics from the day care. This team has strategies of care during crisis, avoiding search for other network services and maintaining the CAPS in its function within the psychosocial model. Final considerations: service operation depends on the nursing team for its permanence condition in all shifts, which leads to the need to think about the legislation reformulation that structures the CAPS III team, in order to guarantee the interdisciplinary care provided by the Brazilian Psychiatric Reform in this device, which should replace hospitalization in a specialized institution.

Objectives: to highlight the main attributes of Convergent Care Research that ratify it as a method of scientific research. Methods: it is a theoretical-reflective study on Convergent Care Research's theoretical-methodological assumptions. Development: Convergent Care Research is compatible with the Social Constructionism paradigm. Convergent Care Research projects have two approaches: practical and conceptual. The Convergent Care Research process corpus contains five phases: conception; instrumentation; scrutiny; analysis and theorizing. Final Considerations: Convergent Care Research rigor encompasses the relationship between research and care practice, and this corresponds to the convergence of these two dimensions. Due to its theoretical foundation and criteria of methodological rigor, Convergent Care Research is aligned with scientific research methods.

Background: Studies on professional identity constitute a challenge for research and instigates many considerations. Objective: To reflect on the process of construction of the professional identity of the female nurse according to Florence Nightingale, a precursor of modern nursing in the world. Key topics under analysis: Theoretical reflection which focuses on two seminal works written by Florence Nightingale: "Notes on Hospitals" (1859), and "Notes on Nursing: what it is and what it is not" (1860), based on the concepts of Claude Dubar about professional identity. Conclusion:The studies pointed out that the professional identity of the nightingalean nurse was shaped in the hospital, stemming from the knowledge and practice of the principles of care and administration, oriented by discipline, defined by Nightingale. They showed that, by implementing her education model, Nightingale caused a detachment from the identity legitimized by religious orders of that period, which may have contributed to the (re/ de)construction of the professional identity of female nurses.
