Nursing Theory: Parts of a Nursing Model
After the discussion on the History of Nursing Theory, let us discuss some parts of a nursing model or theory. All nursing theories or models have several essential parts. In order to be considered a valid nursing theory, a model must include a method of assessment to determine a patient’s individual needs, and a method of implementing and measuring appropriate patient care. Most nursing models can be used to produce a care plan that will document a patient’s treatment by all the healthcare professionals and workers who come into contact with him or her. The care plan should be flexible, so that it can be changed and evaluated daily as the patient’s needs and abilities change.
The care plans themselves will be shaped by the theories behind the nursing model. Care plans fall roughly into five categories: metatheories, grand theories, mid-range theories, min-theories and micro theories, in order from the range of factors considered.
