The process is cyclical in nature, thus ensuring an ongoing process in the synthesis of data, consideration of additional information that may be helpful in identifying appropriate actions, and in establishing criteria for evaluation of the effectiveness of nursing interventions. The PLNU curriculum model, as influenced by the Roy Adaptation Model, divides the assessment phase into two major levels. Assessment of behaviors in these nine areas provide the data base for identification of adaptive or ineffective behaviors in the physiological mode. The diagnostic statement can refer to actual or potential health problems, and can reflect positive adaptation as well as ineffective behavior. Ineffective behaviors are of major concern since they interfere with the person's adaptation to circumstances.
Adaptive behaviors are to be maintained and supported.
Within the Roy Adaptation Model, the nursing diagnosis may be stated in three ways. A statement that refers to behavior within one mode as related to a clustering of the most relevant stimuli. A summary label for behaviors in a specific mode related to the most relevant stimuli. A label that summarizes a behavioral pattern across more than one mode that is affected by the same stimuli. The diagnostic statement in category C provides a more encompassing perspective in planning nursing interventions.
