How can the core function of assessment be applied to public health nursing in a local health department using immunization as an example?

In a local health department, PHNs apply the assessment core function by gathering epidemiological data to determine the rate of children fully immunized against specific communicable diseases, such as measles and H1N1 influenza, with a high immunization rate as an indicator.

Using immunization as an example, assessment is illustrated when public health nurses working in local health departments collect epidemiological data to measure how many children are fully immunized against specific communicable diseases. The evidence cites measles and H1N1 influenza as examples and notes that a high immunization rate, such as greater than 70 percent, is a relevant benchmark for promoting population health.
