What action should a community health nurse take to promote good health in rural homes built before the 1970s?

Teaching residents about the dangers of lead-based paint is crucial for promoting good health in rural homes built before the 1970s because many houses constructed during that time may still contain lead paint. The use of lead in residential paint was banned in 1978 due to its toxic effects, particularly on children, whose developing brains are especially vulnerable to lead exposure. By educating residents about the risks associated with lead-based paint, such as lead poisoning, the community health nurse empowers them to take necessary precautions, such as conducting lead tests, using safe cleaning methods, and recognizing potential hazards.

Additionally, awareness can lead to proactive measures like properly maintaining and, if necessary, safely removing lead paint from their homes, significantly reducing health risks. This action is a sustainable way to ensure a safer living environment and promote long-term health in a demographic that may be at heightened risk due to the age of their homes.
