In the ABCDE approach, which category covers airway issues such as obstruction?

• A. Breathing
• B. Circulation
• C. Airway
• D. Exposure

Answer: (C)

In the ABCDE approach, the first priority is ensuring a clear airway, because without an open airway oxygen can’t reach the lungs no matter what else is happening. The aspect that zeroes in on airway patency and obstruction is the airway stage. It involves checking for signs of blockage and taking steps to relieve it—adjusting position to keep the airway open, suctioning secretions, removing a foreign body if present, and preparing for advanced airway support if needed. This is distinct from the breathing stage, which focuses on how well the patient is ventilating and exchanging gases once the airway is open; circulation addresses perfusion and heart-related issues; and exposure involves examining the rest of the body for injuries or conditions. Since the question centers on airway obstruction, focusing on the airway is the best fit.
