What is a goal in response to an allergic drug reaction?

• A. Counteract the massive release of histamine
• B. Reestablish blood pressure due to the massive release of histamine
• C. Assist the patient in maintaining airway, breathing, and circulation until emergency personnel arrive
• D. Decrease heart rate

Answer: (A)

The key idea is to address the mediator driving the allergic reaction, especially histamine, to halt the reaction cascade at its source. When an allergic drug reaction occurs, histamine and other mediators cause swelling, vasodilation, bronchoconstriction, and potential airway compromise. The primary goal is to counteract that massive histamine release, typically with agents like epinephrine, which both counters the mediator effects and helps stabilize the patient rapidly. This target directly stops the progression of the reaction. Supporting airway, breathing, and circulation is essential during an emergency, and actions to maintain those functions are important. However, they are part of the overall management rather than the principal target of treatment—the central aim is to counteract the histamine-mediated cascade. Decreasing heart rate isn’t the main objective in this scenario, and while blood pressure support may be needed, it follows from treating the mediator release rather than being the primary goal.
