Which cue most supports suspicion of smoke inhalation injury?

Which cue most supports suspicion of smoke inhalation injury?

• A. White particles
• B. Blood-tinged sputum
• C. Black particles
• D. Shortness of breath

Answer: (C)

Smoke inhalation injury is most strongly suggested when evidence of soot exposure is present in the airways. Black particles indicate soot from burning materials and show that inhaled combustion products have reached the airway, signaling potential airway inflammation, edema, and obstruction. This finding directly points to inhalation injury and guides the need for close airway monitoring and possible early intervention. White particles aren’t typical for inhalation injury, blood-tinged sputum can occur but is less specific, and shortness of breath is a common, nonspecific symptom that can arise from many causes.
