The nurse reviews the plan of care for a child with Reye's syndrome. The nurse plans to monitor for which priority complication of this syndrome?

B. Reye's syndrome is characterized by swelling of the brain (cerebral edema), which can lead to increased intracranial pressure (ICP). Monitoring for signs of increased ICP, such as changes in level of consciousness, headache, vomiting, and altered pupil size and reactivity, is crucial for early detection and intervention to prevent neurological deterioration. A. Reye's syndrome primarily affects the liver and brain, leading to liver dysfunction and encephalopathy. While renal involvement can occur in some cases, the priority complication typically relates to liver dysfunction and neurological manifestations rather than renal impairment. C. Hyperglycemia may be present due to liver dysfunction and altered glucose metabolism, but it is not the primary concern compared to neurological complications and hepatic failure. D. Reye's syndrome is not caused by a bacterial infection; it is typically associated with viral illnesses, particularly influenza and varicella (chickenpox).
