C. Advocating for the passage of building codes that require fire-resistant materials.
D. Providing long-term mental health counseling for disaster survivors.
Correct Answer: C
Explanation: Mitigation involves taking proactive measures to prevent or reduce the
impact of a disaster before it occurs. This phase focuses on long-term prevention and risk
reduction, such as structural changes or policy advocacy. This specific action aims to
decrease the vulnerability of the community by ensuring safer infrastructure.

Correct Answer: D
Explanation: In the START (Simple Triage and Rapid Treatment) system, a respiratory
rate greater than 30 breaths per minute indicates the need for immediate intervention.
This patient would be tagged with a red label, signifying a life-threatening condition that
requires rapid care. Assessing respirations is the first step in the START process followed
by perfusion and mental status.
