Final answer:
The first step a nurse would likely take when addressing air pollution in the community is monitoring, as it is essential to gather data on air quality and identify specific pollutants.
Step-by-step explanation:
If a nurse is addressing the problem of air pollution in the community, the first step they would likely take is monitoring. Monitoring is essential to understand the current state of air quality and to determine the specific pollutants that need to be addressed. This step is in line with the procedures established by the Clean Air Act, which emphasizes the importance of establishing and following National Ambient Air Quality Standards. After monitoring, subsequent steps could include setting standards, permitting, and ensuring compliance with those standards. The Clean Air Act and the Environmental Protection Agency (EPA) guide these steps and provide frameworks to improve air quality through both command-and-control regulations and market incentive based policies.
