Determine which conceptual model of nursing you prefer. Then, choose a middle-range nursing theory that has been formulated or derived from your preferred conceptual model of nursing.

 Analyze the parts of your chosen middle-range theory that reveal the derivation characteristics from your chosen conceptual model of nursing. 

An example includes (but not necessarily the model and theory that you will choose) King’s theory of goal attainment (1995), which is a middle-range nursing theory derived in 1981 from King’s conceptual system (1971).
