This study presents some critical reflections "about epistemological constructs in science", on the basis of concepts and preoccupations that are inherent to the scientific and technological advances that influence the construction of knowledge. In accordance with the methodological approach, nursing is seen as "a science under construction". The discussion and arguments focus on distinct aspects/traces of science, which define the nature and objectives of research and which broaden the view of objective knowledge and reality for the field of nursing. In coherence with philosophical and academic reference bases, the author uses the focus of discourse to emphasize/highlight the meaning of constructs as being consistent with the elaboration of significant theories or issues in a field of study and explains her intellectual position in relation to some nursing theses (Ph.D.), in an attempt to explain epistemological aspects of the construction of nursing science.
