A nurse is reviewing the laboratory report of a client who has hyperparathyroidism. The nurse should expect which of the following findings?

Decreased calcium level

Decreased parathyroid hormone level

Increased phosphate level

Increased magnesium level

Answer and Explanation

The Correct Answer is D

A. Decreased calcium level is incorrect. Hyperparathyroidism leads to increased calcium levels (hypercalcemia) due to excessive parathyroid hormone (PTH), which increases calcium release from bones, absorption in the intestines, and reabsorption in the kidneys.

B. Decreased parathyroid hormone level is incorrect. In hyperparathyroidism, PTH levels are elevated, not decreased, due to excessive secretion by the parathyroid glands.

C. Increased phosphate level is incorrect. PTH causes renal phosphate excretion, leading to low or normal phosphate levels, rather than increased levels.

D. Increased magnesium level is correct. Parathyroid hormone increases magnesium reabsorption in the kidneys, leading to elevated magnesium levels in hyperparathyroidism.
