The nurse is caring for a school-aged child with Burkitt lymphoma. A review of the child’s laboratory results reveal serum calcium 8.1 mg/dL (1.9 mmol/L), serum potassium 6.1 mEq/L (6.1 mmol/L), and serum phosphorus 5.9 mg/dL (3.6 mmol/L). Which pathophysiological process is associated with the child’s laboratory results?
Correct Answer: B
Rationale: Tumor lysis syndrome (
B) causes hyperkalemia (potassium 6.1 mEq/L) and hyperphosphatemia (phosphorus 5.9 mg/dL) from rapid cancer cell breakdown, common in Burkitt lymphoma. Hypocalcemia (calcium 8.1 mg/dL) also occurs. Wilms tumor (
A) affects kidneys. Superior vena cava syndrome (
