Final answer:
For mild allergies, antihistamines should be given to the child. If the reaction is severe (anaphylaxis), an epinephrine injection must be administered immediately and the child should receive emergency medical care.
Step-by-step explanation:
If a child experiences an allergic reaction, the appropriate response depends on the severity of the symptoms. For mild allergies, antihistamines are commonly given to alleviate symptoms. For a severe allergic reaction, known as anaphylaxis, an epinephrine injection should be administered immediately to counteract the reaction. People with known severe allergies often carry an EpiPen, which is an auto-injectable device containing epinephrine. After receiving an epinephrine shot, the child should be taken to a hospital or emergency medical facility for further evaluation and treatment.
For mild allergy symptoms, give antihistamines. For severe allergic reactions (anaphylaxis), administer an epinephrine injection and seek emergency medical help.
