Injury with high voltage electrical exposure is commonly associated with which condition requiring monitoring for rhabdomyolysis?

• A. Hypertension
• B. Rhabdomyolysis
• C. Hyperglycemia
• D. Anemia

Answer: (B)

High-voltage electrical injury often causes extensive skeletal muscle damage, and when muscle cells break down they release contents like myoglobin and potassium into the bloodstream. Myoglobin can clog renal tubules and injure the kidneys, so clinicians actively monitor for rhabdomyolysis with serial CK levels, urine testing for myoglobin, and checks of renal function. The main management goal is to prevent acute kidney injury with aggressive intravenous hydration to maintain good urine output, while also watching and correcting electrolyte disturbances, particularly hyperkalemia from the released intracellular potassium. Other conditions listed do not reflect the typical immediate complication pattern after high-voltage injury.
