Public Health Nursing is a specialized field of nursing focused on improving the health of communities and populations. Public health nurses work to prevent disease, promote health, and ensure access to healthcare services. They often collaborate with community organizations, schools, and local governments to address health issues and implement programs that benefit the public. These nurses conduct health assessments, provide education on healthy practices, and advocate for policies that support community health. By addressing social determinants of health, such as nutrition, housing, and education, public health nursing aims to reduce health disparities and improve overall quality of life for individuals and families.
