Final answer:
The PHN's analysis of data on the failure to meet air quality standards is an example of using a health risk factor as a community health profile indicator.
Step-by-step explanation:
When the Public Health Nurse (PHN) analyzes data related to the number and type of United States Environmental Protection Agency air quality standards that a community failed to meet, this data is an example of using a health risk factor as a community health profile indicator. Health risk factors are conditions or behaviors that increase the chance of a person experiencing health problems, such as disease or injury. In the context of community health profiling, examining the extent of air quality standard violations is a way to assess the environmental risk factors that could impact the health of the community members.
