A nurse is assisting in the care of a toddler whose caregivers have questions about allergies. Which of the following should the nurse identify as the most common allergic reaction in children?

A. Allergic rhinitis. Allergic rhinitis is the most common allergic reaction in children, often triggered by environmental allergens such as pollen, dust mites, and pet dander. It presents with symptoms like sneezing, nasal congestion, runny nose, and itchy eyes, affecting a large number of children worldwide. B. Systemic reaction. Systemic allergic reactions, which affect multiple organ systems, are less common than localized reactions such as allergic rhinitis. They are more severe but do not occur as frequently in children as mild to moderate allergic responses. C. Hives. Hives (urticaria) are a common allergic skin reaction, often triggered by food, medications, or insect stings. However, while common, they occur less frequently than allergic rhinitis, which is a more persistent condition. D. Anaphylaxis. Anaphylaxis is a severe and life-threatening allergic reaction, but it is relatively rare compared to allergic rhinitis. It requires immediate medical intervention and is most commonly triggered by food allergies, insect stings, or medications.
