Question

what does the pattern of high calcium and low phosphorus indicate?
hyperthyroidism
hypothyroidism
hyperparathyroidism
hypoparathyroidism

Explanation:

In hyperparathyroidism, parathyroid glands over - produce parathyroid hormone. This hormone increases calcium levels by promoting calcium release from bones, enhancing calcium reabsorption in the kidneys, and increasing calcium absorption in the intestines. At the same time, it promotes phosphorus excretion in the kidneys, leading to low phosphorus levels. Hyperthyroidism and hypothyroidism are thyroid - related disorders not directly associated with this calcium - phosphorus pattern. Hypoparathyroidism would lead to low calcium and high phosphorus levels opposite to the given pattern.

Answer:

C. hyperparathyroidism
