Why suction the airway if there is small amounts of blood?

• A. Because it can get worse and cause problems down the road.
• B. To remove bacteria and prevent infection.
• C. To sample the blood for testing.
• D. To hydrate the airway.

Answer: (A)

Suctioning is done to keep the airway clear and prevent future airway compromise. Even small amounts of blood can obstruct the airway, clot, or mix with secretions to create a line of obstruction that worsens oxygenation and increases the risk of aspiration, especially during transport or patient movement. By removing the blood early, you maintain a patent airway, improve ventilation, and reduce the chances of more serious problems later. The goal isn’t to sample the blood, prevent infection, or hydrate the airway; it’s to prevent obstruction and aspiration by keeping the airway open.
