This article evaluates three nursing theories that can be used to provide a framework for holistic pediatric oncology nursing practice: the Roy Adaptation Model, the Neuman Systems Model, and the Orem General Theory of Nursing. Each theory is compared in terms of its view of man, health, environment, nursing, and the nursing process. Critique of each theory is presented. The decision of which theorist to use as a basis for practice is left to the individual nurse. This article explicates the similarities and differences in the three theories.
