Which core public health function is most appropriate when a public health agency develops guidelines to ensure elder transportation services are equitably available?

• A. Assurance
• B. Policy development
• C. Primary prevention
• D. Public transportation

Answer: (B)

Policy development focuses on creating policies and guidelines to address health issues and promote equitable access. When a public health agency develops guidelines to ensure elder transportation services are equitably available, it is setting standards, defining responsibilities, and outlining how resources and actions will be coordinated across sectors to reduce disparities. This establishes a framework that guides providers, funders, and communities toward consistent, fair access for all older adults.

Assurance comes after, focusing on ensuring those policies are actually implemented, services exist, and meet quality and equity standards. Primary prevention aims to prevent problems before they occur, which isn’t the action described here. Public transportation is the service itself, not the activity of creating policies or guidelines.
