Yhe Theory of Goal Attainment states that “Nursing is a process of action, reaction and interaction by which nurse and client share information about their perception in a nursing situation” and “a process of human interactions between nurse and client whereby each perceives the other and the situation, and through communication, they set goals, explore means, and agree on means to achieve goals.”In this definition, action is a sequence of behaviors involving mental and physical action, and reaction is included in the sequence of behaviors described in action. King states that the goal of a nurse is to help individuals to maintain their health so they can function in their roles. The domain of the nurse “includes promoting, maintaining, and restoring health, and caring for the sick, injured and dying.” The function of a professional nurse is “to interpret information in the nursing process to plan, implement, and evaluate nursing care.”
