Final answer:
The correct answer is 'offering counseling services to at-risk individuals,' as it aligns with secondary prevention efforts to reduce violence in the community by providing immediate support to those who have already been exposed to or are at risk of violence.
Step-by-step explanation:
The secondary prevention intervention that a community health nurse should identify to reduce violence in the community is offering counseling services to at-risk individuals. Secondary prevention strategies are those that are implemented after a problem, such as violence, has occurred, with the aim to halt its progress and prevent further harm.
Interventions such as providing self-defense classes and conducting awareness campaigns are considered primary prevention because they are aimed at preventing violence before it occurs. Reporting suspected abuse is a form of tertiary prevention, intended to minimize the long-term impacts of violence that has already occurred and prevent further damage. Therefore, offering counseling services directly responds to the needs of those who have been exposed to or are at risk of violence and is aligned with secondary prevention efforts mentioned in the literature, such as supporting trauma-informed healing practices and creating safe environments for survivors of violence.
