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.
Nurses should apply principles of human relations to the problems that arise at all levels of experience. Peplau's theory explains the phases of interpersonal process, roles in nursing situations and methods for studying nursing as an interpersonal process. Nursing is therapeutic in that it is a healing art, assisting an individual who is sick or in need of health care. Nursing is an interpersonal process because it involves interaction between two or more individuals with a common goal. The attainment of goal is achieved through the use of a series of steps following a series of pattern. The nurse and patient work together so both become mature and knowledgeable in the process.
