Description:In the evolution of the nursing profession, the phrases nursing care, therapeutic care, caring for others, and related expressions are used by nurses to describe their professional service to others. Members of our society have different thoughts and role expectations about these phrases in relation to the kind of care they receive from nurses. Furthermore, these expressions hold different meanings for nurses in their various care-giving roles, such as to individual clients, families, and community groups they serve. The concept of care is probably one of the least understood ideas used by professional and non-professional people, yet it is probably one of the most important concepts to be understood by human groups. It is a word with multiple social usages in the American culture, and has other meanings in other world cultures. It is time that we study the implicit and explicit meanings associated with the concepts of care and caring so that we can reduce their ambiguities.
