A nursing theory is an idea formed by an experienced and educated nurse who has speculated his/her practice and formed and set of rules and techniques. “The basic purposes of theory are description, explanation, predication, and/or control” (Peterson & Bredow, 2008, p 26). They are modeled by the theorist’s personal observations and insights. Theories are very different due to the fact that Nursing encompasses so many different concepts compared to other professions. I have found that philosophy, science and mathematics are such big components of Nursing. Therefore nursing theorists arise from various points and with various views.
