Answer

Hypocalcemia causes neuromuscular irritability and tetany. Alkalemia induces tetany due to a decrease in ionized calcium, whereas acidemia is protective. This pathophysiology is important in patients with renal failure who have hypocalcemia because rapid correction of acidemia or development of alkalemia may trigger tetany. [6, 7, 8]
