Which of the following is an indication of burns to the respiratory tract?

• A. Increased appetite
• B. Clear throat clearing
• C. Singed eyelashes
• D. Normal voice quality

Answer: (C)

Inhalation injuries to the airway come from exposure to hot gases or smoke, and a key early indicator is signs on the face from close heat exposure. Singed eyelashes clearly show that hot air reached the facial area, suggesting the airway behind them has also been exposed to heat and may be burned. This makes singed eyelashes the most specific and reliable clue among the choices. Increased appetite has no relation to airway burns. Clearing the throat is a non-specific irritation response and doesn’t indicate airway burn by itself. Normal voice quality is unlikely when the airway is injured, since swelling or irritation often changes the voice (hoarseness or loss of voice).
