Final answer:
The correct prevention strategy for assessing evidence of violence during routine encounters is Secondary prevention.
Step-by-step explanation:
The correct prevention strategy for assessing evidence of violence during routine encounters is Secondary prevention. Secondary prevention focuses on early detection and intervention to prevent the progression of a problem. In this case, assessing for evidence of violence during routine encounters aims to identify and intervene in potentially violent situations before they escalate. Primary prevention, in contrast, aims to prevent violence before it occurs by addressing the root causes and promoting healthy relationships and communities, while tertiary prevention deals with long-term care and rehabilitation for survivors of violence.
