In basic patient assessment, what does the acronym ABC stand for?

• A. Airway, Breathing, Circulation
• B. Alertness, Balance, Comfort
• C. Activate EMS, Backboard, Check pulse
• D. Assessment, Bandage, Cooling

Answer: (A)

The main idea tested is the order and meaning of the ABCs used in basic patient assessment. Airway, Breathing, Circulation is the standard sequence because keeping the airway open is the first priority; without a clear airway, oxygen can’t reach the lungs regardless of breathing effort or heart and blood flow. Once the airway is secured, you assess Breathing to ensure the person is ventilating adequately and can receive oxygen. If breathing is insufficient, you provide support to restore ventilation. Finally, Circulation is checked to ensure there’s enough blood flow to deliver oxygen to tissues; poor circulation can lead to rapid deterioration even if the airway is clear and breathing is adequate. This order reflects the most immediate threats to life and guides the priorities in initial assessment and intervention. The other options don’t reflect this established sequence or its focus on life support. They mix different concepts (alertness and comfort, trauma-oriented steps, or non-patient-priority actions) that aren’t part of the standard airway–breathing–circulation framework used in basic assessment.
