Objective: To describe the scientific production of the International Classification for Nursing Practice throughout dissertations and theses published by nurses in Brazil from 1996 to 2016. Method: A bibliometric, descriptive, quantitative documentary study, carried out from October/2015 to July/2016 on the sites of the Center of Studies and Research in Nursing (CEPEn), at the thesis and dissertation banks of the Coordination of Improvement of Higher Education Personnel and of the Plataforma Sucupira (Sucupira Platform). Results: There were 108 productions, 30 theses and 78 dissertations. In 2014, there was the largest number of publications (19). The Graduate Program in Nursing of the Universidade Federal da Paraíba had the highest number of productions (23). Regarding the theme, the use in clinical practice was highlighted (69), followed by the elaboration of terminology subsets (17). Conclusion: The Brazilian scientific production setting on ICNP® is expressive, evidencing this system as a tool that allows the provision of systematic care.

Objective: Classify the diagnoses in the conceptual framework of vulnerability of Ayres and in the Orem's self-care theory; Elaborate operational definitions of nursing diagnoses for elderly women vulnerable to HIV/AIDS. Method: A descriptive exploratory study, developed from March to December 2016 in the stages: 1. Classification of diagnoses in the conceptual framework of vulnerability of Ayres and in the Orem's self-care theory; 2. Operational definition of nursing diagnoses. Results: 70 nursing diagnoses were classified in the conceptual framework of vulnerability of Ayres and Orem's self-care theory, and their operational definitions were constructed, where 75.7% of these were validated. Final consideration: Diagnoses represent conditions that make older women vulnerable to HIV/AIDS and are linked to their self-care practices. Operational definitions contribute to a systematic approach to care and greater clarity in its implementation.

Objective: To map the nursing interventions of the Terminology Subset for elderly women with HIV/AIDS-related vulnerabilities in the International Classification for Nursing Practice 2019/2020, according to the guidelines of the ABNT Standard ISO/TR 12.300/2016. Method: This is a descriptive exploratory study of terminological mapping, in which interventions underwent the technique of validation by consensus and human mapping. Interventions reaching 100% agreement regarding practical usefulness and classification in the Theory of Nursing Systems were validated. Finally, human mapping was performed with a single purpose and oriented from source concepts to target concepts. Results: A total of 218 interventions were validated. Following mapping, the numbers were updated due to the cardinality relationship, resulting in 221 interventions, 170 of which are not, and 51 are included in the International Classification for Nursing Practice 2019/2020. Conclusion: Mapping of the Terminological Subset of the International Classification for Nursing Practice 2019/2020 culminated in the review and update of the proposed terminology, and confirmed the usefulness of the classification system through pre-coordinated concepts.

Objective: to build a term database relevant to nursing practice in the context of COVID-19 infections. Methods: this is a methodological, documentary study, carried out from March to June 2020 at ICNP®/ Universidade Federal da Paraíba center, considered a reference for research and dissemination of ICNP® in Brazil. The findings were collected in databases and analyzed using the PorOnto tool, the consensus technique and the mapping of terms with ICNP®, version 2019/2020. Results: 1,134 relevant terms were identified in literature. When submitted to the mapping technique with the terms of ICNP® Seven Axis Model, it resulted in 531 constant terms and 603 nonconstant terms in this classification. Final considerations: It is proven that nursing practice terms, even in a specific context, are present in the literature and are representative in ICNP®, which will enable the future development of a terminological subset in the context of coronavirus infections.
