Myra E. Levine: a theoretic basis for ET nursing.

ET nursing is a challenging specialty that requires exact knowledge, complex skills, and a holistic approach to patients with wound, ostomy and continence problems. Myra E. Levine's conceptual framework for nursing practice is described and applied to ET specialty practice nursing. Examples of Levine's four conservation principles-energy, structure, personal integrity, and social integrity-are integrated into the nursing care of patients' wound, ostomy, and continence problems.
