Final answer:
As a tertiary prevention strategy in response to the increased incidence of violence in the community, the community health nurse should provide counseling and support for victims.
Step-by-step explanation:
Tertiary prevention focuses on reducing the impact of a disease or injury that has already occurred. In the context of violence, the goal of tertiary prevention is to support and assist the victims. Option b, providing counseling and support for victims, is the most appropriate action as a tertiary prevention strategy. Counseling can help victims cope with the trauma and provide them with the necessary support systems.
Options a, c, and d are not considered tertiary prevention strategies. Implementing community policing programs (option a) focuses on primary prevention by addressing the root causes of violence. Offering self-defense classes to community members (option c) also falls under primary prevention as it aims to prevent violence through preparedness. Advocating for stricter law enforcement measures (option d) is more aligned with secondary prevention, which focuses on early detection and intervention.
