nursing process model, a conceptual framework in which the nurse-patient relationship is the basis of the nursing process. The nursing process is represented as dynamic and interpersonal, the nurse and the patient being affected by each other’s behavior and by the environment around them. Each successful two-way communication is termed a “transaction” and can be analyzed to discover the factors that promote transactions. The constraints that the various systems in the environment (personal, interpersonal, and social) place on the development of the relationship are also examined. The nurse views the patient as a person with whom to have transactions that achieve defined adaptive objectives toward the goal of health.
