Question 45Safety & Environmental - QMED

The correct answer is C) complete obstruction of respiratory passages. Severe airway burns, such as those caused by inhalation of hot gases or chemicals, can lead to swelling and edema of the respiratory tract. This can result in complete obstruction of the airway, preventing normal breathing. The other answer choices do not accurately reflect the primary effect of severe airway burns, which is the potentially life-threatening obstruction of the respiratory passages.
