A community health nurse is reviewing the emergency response plan for their community. Which of the following interventions occurs at the secondary level of prevention?

Secondary prevention focuses on early detection and prompt treatment to limit the severity of an event or illness. Triaging clients during a disaster is a secondary-level intervention because it identifies and prioritizes those already affected to prevent further harm. Primary prevention prevents the disaster or reduces its occurrence (e.g., drills, identifying vulnerable populations). Tertiary prevention rehabilitates those affected (e.g., mental health counseling after the disaster).
