The author points out the fundamental questions in nursing - science and art. Nursing is considered both as a social practice and as a profession that encompasses scientific practice and the construction of knowledge. Thus, Nursing is understood as a "science under construction" or as specific knowledge, even if it is imprecise and, therefore, on its way to become scientific due to its evidences. In other words, knowledge that is justified not by total precision, on the contrary, by the need to find answers to the question about raising the epistemological reach of nursing research results - its knowing and knowing what to do. The discussion emphasizes the crucial nature of nursing care.
