The nurse is reviewing lab results of a 43-year-old with hyperparathyroidism. Which of the following abnormalities would the nurse expect?
Explanation
• Excess parathyroid hormone secretion results in hypercalcemia by removing calcium from the bone.
• The most common clinical presentation is asymptomatic hypercalcemia.
• Hyperparathyroidism results from oversecretion due to a parathyroid tumor (primary hyperparathyroidism) or in response to hypocalcemia (secondary hyperparathyroidism).
• Hyperparathyroidism causes an increase in phosphate excretion, leading to hyperphosphaturia.
• Hypophosphatemia results from increased phosphate excretion, but is usually on the lower end of normal, occurring in less than half of all cases.
