Q: Which of the following best describes the common clinical manifestations of hypoparathyroidism?
Explanation: Hypoparathyroidism usually presents itself as a disorder of calcium metabolism in which serum calcium levels of the patient decrease while levels of phosphate increase in an inversely proportional manner. Low-serum calcium levels may precipitate a potentially serious condition known as tetany. To prevent the development of this disorder and to treat the hypoparathyroidism, calcium supplements such as calcium gluconate, calcium carbonate, or calcium lactate may be prescribed.
