Final answer:
To improve primary prevention efforts in the community, the public health nurse could provide safety education, advocate for infrastructure improvements, and collaborate on interim safety solutions.
Step-by-step explanation:
To enhance primary prevention efforts in the described community with lower incomes, a high rate of pedestrian and motor vehicle accidents, sidewalks in poor condition, and no access to trails for physical activities, the public health nurse could take several actions. Firstly, the nurse could provide pedestrian and motor vehicle safety education to local community residents. Educating the community about the importance of safety, the proper use of crosswalks, and defensive walking and driving can help reduce accidents. Secondly, the nurse could advocate to local community leaders to prioritize the area for infrastructure improvements. This could involve campaigning for the repair of sidewalks and the creation of trails, which would not only enhance safety but also encourage physical activity. Thirdly, in collaboration with the local street department, attention could be placed on immediate interim solutions to improve safety, such as temporary signage or painted crosswalks, until permanent infrastructure improvements can be made.
