Which sign is a key feature of smoke inhalation injury beyond eye irritation?

• A. Watery, irritated eyes
• B. Abnormal breath sounds, such as stridor or wheezes
• C. Severe cough
• D. Dizziness

Answer: (B)

Smoke inhalation injures the airway tissue, so signs that airway involvement is occurring are a key indicator beyond eye irritation. Stridor signals swelling in the upper airway that can obstruct breathing, while wheezes reveal inflammation and narrowing in the lower airways from bronchospasm. These abnormal breath sounds point directly to airway compromise, which is the main danger in inhalation injuries. In contrast, watery eyes are just eye irritation, a severe cough can occur for various reasons and isn’t as specific to airway injury, and dizziness is nonspecific. Recognizing abnormal breath sounds guides urgent actions like providing high-flow oxygen and preparing for airway support if the situation worsens.
