Q: Following may happen in pure Respiratory alkalosis (Hypocapnia) except

A) Hypokalemia

B) Hypercalcemia

C) Hypophosphatemia

D) Hyponatremia

E) Hypochloremia

Answer: B 

Clinical Significance:: Alkalosis causes hypokalemia and hypophophatemia due to increased intracellular shifts. But hypocalcemia is due to increased binding of calcium to serum albumin due to the change in PH. Most of the symptoms present in respiratory alkalosis are due to hypocalcemia. Alkalosis also causes hyponatremia and hypochloremia.
