Emergency Medical Technician (EMT) Trauma Practice Test

Firefighters have rescued a man from his burning house. He is conscious and alert but experiencing significant respiratory distress. He has a brassy cough and singed nasal hairs. The MOST immediate threat to this patient's life is:

1. Airway swelling

2. Hypothermia

3. Severe burns

4. Severe infection

The correct answer is: Airway swelling

In this scenario, the man who was rescued from a burning house is experiencing significant respiratory distress, has a brassy cough, and singed nasal hairs, which are indicative of exposure to smoke and potential inhalation injury. The MOST immediate threat to this patient's life is airway swelling. Inhalation injury from smoke can cause edema and swelling in the upper airway, leading to airway compromise and respiratory distress. Therefore, ensuring a clear and patent airway is crucial in this situation to prevent respiratory failure and maintain adequate oxygenation. Addressing airway swelling and ensuring proper oxygenation should be the top priority for this patient.
