Grand theories offer a conceptual framework of which concepts and principles of the discipline can be identified. Middle range theories are more specific and target particular situations while practice theories explore only one particular situation found in nursing.
Nursing theories have the ability to provide a foundation to nursing care in daily practice. They establish a way for nurses to explain or predict everyday experiences they encounter. They serve as guide to clinical practice because they help nurses identify concepts, obtain analytical skills as well as use critical thinking during assessment, intervention and evaluation processes.
