Abstract

This paper provides a comprehensive overview of the core functions and policies integral to public health nursing, focusing on health advancement, illness prevention, and health protection. The study categorizes essential public health nursing services into three primary areas: health advancement, illness prevention, and health protection. Each service is delineated within these categories, ensuring a unique representation to prevent redundancy. Key policies underpinning these functions include Building Healthy Public Policy, Creating Supportive Environments, Strengthening Community Action, Reorienting Health Services, and Developing Personal Skills. Additionally, prevention-oriented policies such as Reproductive & Family Health, Prevention of Chronic Illness, Nutrition/Food Security, Mental Health Protection, Communicable Diseases, Protection from Injury, and Environmental Health are examined. This framework highlights the multifaceted role of public health nursing in fostering community health and well-being through targeted interventions and strategic policy implementation.
