Emergency Medical Technician (EMT) Intermediate Practice Exam

The most immediate threat to life that is associated with angioedema is:

1. swelling of the upper airway

2. fluid accumulation in the abdomen

3. severe headaches

4. chest pain

The correct answer is: swelling of the upper airway

The most immediate threat to life associated with angioedema is indeed the swelling of the upper airway. Angioedema is characterized by localized swelling due to the accumulation of fluid in the deeper layers of the skin, often resulting from an allergic reaction. When swelling occurs in the upper airway, it can lead to obstruction of breathing passages, which poses a significant risk of asphyxiation. This condition can progress rapidly and may restrict airflow, making it critical for emergency responders to recognize and act quickly to secure the airway. In severe cases, if the airway becomes compromised, it can lead to respiratory failure and death if not treated promptly. While fluid accumulation in the abdomen, severe headaches, and chest pain can be symptoms associated with various medical emergencies, they do not represent an immediate threat to life in the same way that upper airway swelling does in the context of angioedema. Hence, addressing airway swelling is the priority in emergency medical situations involving this condition.
