A patient is admitted to the hospital with a diagnosis of primary hyperparathyroidism. A nurse checking the patient's lab results would expect which of the following changes in laboratory findings?

  • A. Elevated serum calcium
  • B. Low serum parathyroid hormone (PTH)
  • C. Elevated serum vitamin D
  • D. Low urine calcium
Correct Answer: A

Rationale: In primary hyperparathyroidism, there is excess secretion of parathyroid hormone (PTH) leading to increased resorption of calcium from bones and decreased excretion of calcium by the kidneys. This results in elevated serum calcium levels. Elevated serum calcium is a hallmark characteristic of primary hyperparathyroidism, making it the correct answer. Low serum parathyroid hormone (PTH) (Choice B) is incorrect because primary hyperparathyroidism is associated with elevated PTH levels due to the malfunction of the parathyroid glands. Elevated serum vitamin D (Choice C) is incorrect because primary hyperparathyroidism is not typically associated with elevated vitamin D levels. Low urine calcium (Choice D) is incorrect as primary hyperparathyroidism leads to decreased calcium excretion by the kidneys, resulting in high levels of calcium in the urine.
