A nurse is reviewing the laboratory test results from a client who has prerenal acute kidney injury (AKI). Which of the following electrolyte imbalances should the nurse expect?

A. Hypercalcemia is not typically associated with prerenal AKI; calcium levels may be normal or low. B. Hyperkalemia is common in AKI due to impaired renal excretion of potassium, especially in prerenal cases where perfusion is decreased. C. Hypernatremia is less common; more often, dilutional hyponatremia may occur if fluid shifts are present. D. Hypophosphatemia is not typical; phosphate levels tend to rise in AKI due to decreased excretion.
