A nurse is caring for a toddler in the outpatient setting. Exhibits Complete the following sentence by using the lists of options. The nurse recognizes the toddler has likely developed dropdowndue todropdown.

Rationale for Correct Answer: Reye syndrome presents with vomiting, lethargy, confusion, and rapid progression to decreased consciousness or coma, all of which are evident in this toddler. The toddler was recovering from influenza A (a viral illness) and received aspirin alternated with acetaminophen for fever management. The use of aspirin during a viral infection is the primary risk factor for developing Reye syndrome. The manifestations of vomiting, lethargy, and difficulty to rouse reflect cerebral edema and hepatic dysfunction, hallmark features of Reye syndrome. Rationale for Incorrect Options: Bronchitis: Characterized by productive cough, wheezing, or chest congestion, not vomiting or altered consciousness. The lungs are clear and respirations unlabored, ruling this out. Gastroenteritis: Typically presents with diarrhea and dehydration, not altered level of consciousness or neurologic symptoms. Oseltamivir administration: This antiviral is used for influenza treatment and is not associated with Reye syndrome. Acetaminophen administration: Overdose can cause liver toxicity, but not encephalopathy with vomiting and lethargy after viral illness in the absence of overdose symptoms. Aspirin administration: The correct cause; aspirin triggers mitochondrial dysfunction in the liver and brain following viral infections, leading to Reye syndrome.
