Question: 1 / 400

What is a key symptom of anaphylaxis?

Delayed response to allergens

Localized swelling

Difficulty breathing

A key symptom of anaphylaxis is difficulty breathing, which arises due to severe swelling of the airways and bronchi as a response to allergens. This acute reaction is life-threatening and can lead to airway obstruction, making it critical for first responders to recognize this symptom quickly. Anaphylaxis is characterized by rapid onset of symptoms, typically occurring within minutes of exposure to an allergen, and difficulty breathing is often accompanied by other systemic symptoms such as hives, throat swelling, and a drop in blood pressure. Recognizing difficulty breathing as a central symptom helps healthcare providers prioritize immediate intervention, such as administering epinephrine to counteract the severe allergic reaction.
