Objective: to analyze the Theory of Unpleasant Symptoms according to the model proposed by Walker and Avant. Method: a descriptive-reflexive study developed in the first half of 2016. He used the first five phases proposed by the Walker and Avant model: identification of the origins of the theory; examination of the meaning of the theory; logical adequacy; utility; degree of generalization and parsimony of theory. Results: the study allowed the reflection on the Theory of Unpleasant Symptoms, considering the multidimensionality of the symptoms and the potential stimulation between them. It was identified the relations between the main concepts used to construct the theory: physiological, psychological and situational factors, followed by performance, suffering, duration, quality, intensity and unpleasant symptoms. Conclusion: the Theory of Unpleasant Symptoms presents a structured theoretical framework, presenting logical meaning, through well-defined concepts and relations, which make possible its use in practice, teaching and nursing research.

based on the conceptual analysis of the phenomenon, it was possible to identify the antecedents, attributes, and consequences of Hospitalization Anxiety in children. We recommend the continuation of the study validating the essential characteristics presently identified as a way to join knowledge gathered and professional practice.

Objective: to describe the process of developing a nursing diagnosis regarding child anxiety following hospitalization, which is to be submitted to the international classification for nursing practice, in accordance with the guidelines set out by the International Council of Nurses and the ISO standard 18104:2014. Method: this methodological study includes a conceptual analysis that bases itself on analyzing the phenomena of anxiety and hospitalization, while identifying the critical attributes of the concept and developing an operational definition. Results: all the criteria for including a new nursing concept were followed and there was no violation of the framework of the International Classification for Nursing Practice with the proposed inclusion, since the concept of anxiety already exists in this classification system and the concept of anxiety from hospitalization would be considered a species or subclass of this concept.Conclusion: this analysis of the concept of hospitalization anxiety in children allowed its meaning to be clarified and, consequently, understanding to be constructed regarding its practical applicability. This achievement contributed in terms of providing incentive to develop new proposals for nursing diagnoses to be included in the International Classification for Nursing Practice.

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.

Pesquisa exploratória descritiva, cujo objetivo foi construir enunciados de diagnósticos de enfermagem para as fases do crescimento e do desenvolvimento da criança na atenção básica, utilizando-se os termos identificados a partir do Manual do Crescimento e Desenvolvimento do Ministério da Saúde e a Classificação Internacional para a Prática de Enfermagem (CIPE®). Foram construídos 111 enunciados de diagnósticos de enfermagem, que foram classificados de acordo com as etapas do desenvolvimento e do crescimento da criança, 23, no período neonatal; 40, na primeira infância; e 48, na fase pré-escolar. Acredita-se que a construção de enunciados de diagnósticos de enfermagem para as fases do crescimento e do desenvolvimento da criança contribuem diretamente para melhorar a qualidade da assistência prestada. Pretende-se proceder à validação clínica dos enunciados de diagnósticos de enfermagem, a fim de possibilitar a integração do conhecimento científico com a prática, na assistência à criança na atenção primária à saúde.
