Definition of Public Health Nursing. Public health nursing is the practice of promoting and protecting the health of populations using knowledge from nursing, social, and public health sciences. Public health nursing is a systematic process by which: The health and health care needs of a population are assessed in order to identify subpopulations, families and individuals who would benefit from health promotion or who are at risk of illness, injury, disability or premature death.
Health Promotion Model. The Health Promotion Model was designed by Nola J. Pender to be a complementary counterpart to models of health protection.. It defines health as a positive dynamic state rather than simply the absence of disease. Health promotion is directed at increasing a patient's level of well-being. The health promotion model describes the multidimensional nature of persons as they interact within their environment to pursue health.
