Correct Answer is D
Explanation
A. "Get the child tested for Reye's syndrome if the child exhibits fever, vomiting, and lethargy.": While these are symptoms of Reye's syndrome, prevention focuses on avoiding triggers like salicylates during viral illnesses, not merely recognizing symptoms.
B. "Use aspirin instead of acetaminophen for children with viral illness.": Aspirin increases the risk of Reye's syndrome in children with viral illnesses.
C. "Advise parents to have their children immunized against Reye's syndrome.": There is no vaccine for Reye's syndrome; prevention relies on avoiding salicylate use during viral infections.
D. "Avoid giving salicylate-containing medications to a child who has a viral syndrome.": Salicylates, such as aspirin, are the primary risk factor for Reye's syndrome, so avoidance is critical.
