A nurse in an emergency department is caring for a preschool-age child who has acute acetylsalicylic acid poisoning. Which of the following should the nurse expect?

A. Jaundice: Jaundice is a sign of liver dysfunction or hemolysis and is not an expected manifestation of acute acetylsalicylic acid (aspirin) poisoning. While severe toxicity can affect multiple organs, jaundice is not a typical early or common symptom in children with aspirin overdose. B. Hyperpyrexia: Acute aspirin poisoning can disrupt the body’s thermoregulatory center, leading to elevated body temperature (hyperpyrexia). Other common manifestations include tachypnea, nausea, vomiting, and altered mental status. Hyperpyrexia is particularly concerning in severe toxicity and requires prompt intervention. C. Neck vein distention: Neck vein distention is usually associated with cardiac or fluid overload conditions, such as heart failure or pericardial tamponade. It is not a clinical feature of aspirin poisoning and would not be expected in this scenario. D. Polyuria: While aspirin toxicity can lead to dehydration from vomiting or sweating, polyuria is not a characteristic sign of acute aspirin poisoning. Any changes in urine output would more likely result from secondary dehydration rather than a direct effect of the drug.
