Final answer:
Public Health Nurses can function at three levels of the Intervention Wheel: individual/family, community, and systems, incorporating 17 different public health interventions tailored to the needs of the population served.
Step-by-step explanation:
The levels of intervention at which a Public Health Nurse (PHN) can function are represented by the Public Health Intervention Wheel. This wheel includes three levels of practice: individual/family, community, and systems. At the individual/family level, PHNs provide interventions to individuals or families that are direct and specific. At the community level, interventions are directed towards populations within a community. Lastly, at the systems level, PHNs work on change and improvements in systems or policies influencing health.
The Intervention Wheel is further divided into 17 public health interventions that fall under these three levels, such as surveillance, disease and health event investigation, outreach, screening, case management, delegated functions, health teaching, counseling, consultation, coalition building, community organizing, advocacy, social marketing, policy development and enforcement, and research.
PHNs employ these interventions based on the needs of the population they serve, taking into account the social determinants of health, epidemiological data, and the available resources.
