In trauma assessment, what does the acronym Dr ABC primarily refer to?

• A. Airway, Breathing, Circulation, Disability
• B. Airway, Circulation, Disability
• C. Breathing, Circulation, Disability
• D. Airway, Breathing, Circulation

Answer: (D)

The main idea being tested is the order of priorities in the trauma primary survey. DR ABC centers on life-saving steps, starting with Airway to ensure the airway is open, then Breathing to guarantee adequate ventilation and oxygenation, and finally Circulation to control bleeding and maintain perfusion. This sequence is why the trio Airway, Breathing, Circulation is the best fit: without a patent airway, breathing cannot happen; without effective breathing, oxygen delivery fails regardless of circulation; and without circulation, even well-ventilated lungs cannot sustain tissue perfusion. Disability and other assessments come after these core steps, which is why including them early or omitting Airway or Breathing would not reflect the primary focus of the acronym.
