What are the three core functions of public health nurse?

Assessment: Public health nurses assess the health needs of individuals, families, and communities. This includes identifying risk factors, such as poverty, lack of access to care, and unhealthy behaviors, as well as identifying strengths and resources that can be used to improve health.

Policy Development: Public health nurses work with policymakers to develop policies that promote health and prevent disease. This may involve advocating for legislation that increases access to care, funding for public health programs, and regulations that protect the environment and promote healthy behaviors.

Assurance: Public health nurses ensure that essential public health services are provided to all individuals and families, regardless of their ability to pay. This may involve providing direct services, such as immunizations, screenings, and health education, as well as working with other organizations to ensure that these services are available to everyone.
