• A. Not sure
• B. True
• C. False
• D. Not applicable

Answer: (B)

In emergency triage, color codes are used to signal how quickly a patient needs care. Red is reserved for immediate life-threatening conditions that require rapid assessment and intervention to prevent death. This is why red indicates life-threatening conditions: it quickly flags those who need the highest priority, such as severe airway issues, hemorrhage, or major trauma, so responders can act fast. Other colors (like yellow for urgent but not immediately life-threatening, green for minor injuries, and black for deceased or unsalvageable) help sort patients by urgency, but the defining idea is that red means immediate life-threatening need.
