A community health nurse identifies obesity as a problem in a middle school and then makes health information available to students. This step represents which core public health function?

• A. Assessment
• B. Assurance
• C. Policy development
• D. Research

Answer: (A)

The main idea here is how public health activities are categorized to address population health. Assessment involves gathering and analyzing information about the health status and needs of a community and then sharing that information to inform action. When the nurse identifies obesity as a problem in a middle school, that’s collecting and interpreting data about health status. Providing health information to students is disseminating findings to the community so they understand the issue and can take steps. Together, these actions illustrate assessing a health problem and communicating about it, which is the assessment function.

Why the others don’t fit as well: assurance focuses on ensuring that necessary services and policies are available and implemented, not primarily on identifying problems and sharing information. Policy development is about creating policies to address health issues, not the initial assessment and dissemination of data. Research is about generating new knowledge through studies, which isn’t what’s described in this scenario.
