What is the main concern with smoke inhalation?

• A. Dehydration.
• B. Liver injury.
• C. Kidney failure.
• D. Airway.

Answer: (D)

Smoke inhalation primarily threatens the airway because the inhaled heat and caustic substances injure the lining of the nose, throat, and especially the airways. This causes edema, increased mucus, and potential sloughing of the mucosa, which can rapidly narrow or block the passages and impair ventilation. If the airway becomes compromised, oxygen delivery to the lungs drops quickly, making airway management—often early intubation—critical. Dehydration and organ injuries like liver or kidney damage can occur with severe burns, but they are not the immediate, airway-specific threats posed by inhalation.
