Which of the following is NOT a component of the allergic reaction/anaphylaxis protocol?

• A. Epinephrine auto-injector
• B. O2 saturation PRN
• C. Remove allergen
• D. Administer aspirin

Answer: (D)

Emergency management of anaphylaxis centers on rapid, life-supporting actions: reversing the allergic reaction with epinephrine, ensuring adequate breathing and oxygenation, and removing the ongoing trigger. Epinephrine is the cornerstone because it quickly counteracts airway swelling and bronchospasm, improves blood pressure, and limits further mediator release from mast cells. Having an epinephrine auto-injector available and using it promptly when anaphylaxis is suspected is essential in the protocol.

Monitoring oxygen saturation and providing supplemental oxygen as needed helps maintain tissue oxygenation during respiratory compromise, a common feature of severe reactions. Removing the allergen or stopping exposure prevents ongoing stimulation of the reaction and supports overall improvement.

Aspirin does not play a role in the allergic reaction/anaphylaxis protocol. It does not address the underlying mechanism and can introduce unnecessary risks, so it is not used in this context.
