Nurses promoting patient's health--is there a need to discuss the concept of health in nursing? The concept of health has been studied from different points of view in order to determine what health is. The nature of health is problematic and value based. In nursing where the health and wellbeing of patient is of interest to the practice, there is a need to become aware of what kind of health nurses are promoting. Does health promotion mean the same as disease prevention or does health have any positive content? There is need to get more information about health by studying it from different perspectives, for instance as perceived by clients. Also in nursing practice nurses should discuss the purpose of their action.
