Every the practice of nursing have originated.

Every day, nursing professionals question
aspects of daily practice; a fact that forces us to reflect on the meaning of
what is being done. In this sense, from various approaches, several authors
have contributed their knowledge in order to define and explain the essence of
nursing care. As result, different theories and models that guide the practice
of nursing have originated. For example: Dorothea Orem’s theory of self-care is
a great general theory formed by three other related sub-theories: Self-care
theory, self-care deficit theory and nursing systems theory. Each of them is
based on key concepts that make up their central idea.

Dorothea Orem was a prominent nurse who was
born in 1914 in Baltimore, Maryland and died on June 22, 2007, with 94 years of
age. She was the creator of the Theory of Self-Care. Within her trajectory as a
theorist, no nurse influenced more than another, but it was a set of all with
which she had contact, and the experience of them, including his own, which
served as a theoretical source. Orem formulated its concept of nursing in
relation to self-care as part of a study on the organization and administration
of hospitals. Orem’s interpretations of nursing science as a practical science
are basic to understanding how empirical evidence is collected and interpreted.
