<prompt> Carpopedal spasm in hyperventilation occurs becauseIncreased calcium uptake by sarcoplasmic reticulum of musclesIncreased calcium uptake by bonesIncreased calcium binding to plasma proteinIncreased urinary excretion of calcium  <response>: Answer- C. Increased calcium binding to plasma proteinCarpopedal spasm and tetany is due to hypocalcemia.The alkalosis that result from hyperventilation may worsen the hypocalcemia by increasing the fraction ionized calcium bound to plasma protein.
