This learning activity examines pediatric allergy management across the full pediatric lifespan, with a focus on anaphylaxis recognition, evidence-based acute management, and long-term disease prevention. Nurses will explore developmental differences in allergic presentations, current epinephrine dosing guidelines, the evolving role of corticosteroids and antihistamines, and the construction of personalized anaphylaxis action plans. The content also addresses the atopic march, emerging therapies including oral immunotherapy and biologics, and the nurse's role in equity-centered, family-focused allergy care.
