Social justice: added metaparadigm concept for urban health nursing.

Historically, the nursing metaparadigm has been used to describe 4 concepts of nursing knowledge (person, environment, health, and nursing) that reflect beliefs held by the profession about nursing's context and content. The authors offer an assessment of the metaparadigm as it applies to community and public health nursing in urban settings and offer an amendment of the metaparadigm to include the central concept of social justice. Each of the metaparadigm concepts and the central concept of social justice is discussed as it applies to a model of urban health nursing teaching, research, and practice.
