What is the purpose of airway suctioning in an unresponsive patient?

• A. To clear secretions and maintain airway patency; avoid excessive suctioning depth.
• B. To deliver oxygen.
• C. To hydrate the airway with fluids.
• D. To immobilize the cervical spine.

Answer: (A)

Suctioning in an unresponsive patient is used to clear secretions and keep the airway open. When someone can’t protect their airway, mucus, blood, vomit, or other material can accumulate and block the passages, increasing the risk of hypoxia and aspiration. By removing that material, suctioning helps you ventilate more effectively and reduces obstruction.

Do it carefully—don’t insert the suction device too deeply, because deeper suctioning can cause airway injury or a vagal response that slows the heart. Use short bursts (about 10 seconds or less in adults) and withdraw while suction is active, and preoxygenate if you can to minimize the drop in oxygen levels. Afterward, reassess the airway and ventilation.

This is not for delivering oxygen, hydrating the airway, or immobilizing the neck; those are separate considerations in airway management.
