Abstract

Public health nursing plays a critical role in promoting community health and preventing disease. This paper explores the core functions of public health nursing, emphasizing their impact on health outcomes and community well-being. The essential functions include health assessment and surveillance, policy development, health education, and direct care. Through these roles, public health nurses address the needs of diverse populations, advocate for health equity, and implement evidence-based interventions. The integration of these functions into community health strategies is crucial for enhancing public health infrastructure and addressing systemic health challenges. By examining case studies and current practices, this paper highlights the significance of public health nursing in shaping effective public health policies and practices.
