Which of the following is a sign that the airway may be blocked?

• A. Casualty is in distress and indicates they can't breathe properly
• B. Casualty is making snoring or gurgling sounds
• C. Visible blood or foreign objects are present in the airway
• D. Maxillofacial trauma is observed

Answer: (C)

In airway assessment, a clear indicator that the airway may be blocked is seeing blood or a foreign object in the airway. That visual presence confirms something is physically obstructing the passage, which requires immediate action to remove the obstruction or protect the airway and ensure ventilation. Other signs can suggest airway problems but are less definitive. Casualty in distress who says they can’t breathe properly points to airway compromise in general, but it doesn’t show what specifically is blocking it. Snoring or gurgling sounds can indicate partial obstruction and poor airway clearance, not a definite object blocking the airway. Maxillofacial trauma raises the risk of airway problems due to swelling or bleeding, but it isn’t a direct sign that the airway is currently blocked. So, the most direct sign that the airway is blocked is the visible presence of blood or a foreign object in the airway.
