This summarizes Imogene King's Goal Attainment Theory of Nursing. King defines nursing as a process of interaction between nurse and client to establish goals and carry out actions to achieve them. She views humans as open systems interacting with their environment. The nursing process involves assessment, nursing diagnosis, planning, implementation and evaluation carried out through communication between nurse and client. The goal is for clients to attain their health goals through this process of mutually setting and working towards goals.
