Question: You are the first responder to an incident where a worker has fallen from height and is unconscious, not breathing, and has significant external bleeding. After ensuring scene safety and requesting emergency services, what is the sequence of actions you should take?

Answer options:

• Check for pulse, open airway, stop bleeding, begin CPR.
• Open airway, check for breathing, begin CPR, control bleeding. ✅ Control bleeding, open airway, check for breathing, begin CPR.
• Check for responsiveness, control bleeding, begin CPR, open airway.

Correct answer: Control bleeding, open airway, check for breathing, begin CPR.

Explanation: In cases of severe bleeding and unconsciousness without breathing, controlling massive bleeding often takes precedence or occurs simultaneously with airway management and CPR. The 'C-A-B' (Circulation, Airway, Breathing) sequence is modified to prioritize life-threatening hemorrhage control in trauma, as per current first aid guidelines (e.g., Canadian Red Cross).
