A nurse is collecting data from a client who has hypoparathyroidism. Which of the following findings should the nurse expect?

Choice A reason: Phosphate 5.7 mg/dL is an elevated value, as the normal range is 2.5 to 4.5 mg/dL. Hypoparathyroidism causes low levels of parathyroid hormone (PTH), which regulates calcium and phosphorus balance in the body. Low PTH leads to low calcium and high phosphorus levels in the blood.

Choice B reason: Vitamin D 25 ng/mL is a normal value, as the normal range is 20 to 50 ng/mL. Hypoparathyroidism does not directly affect vitamin D levels, but vitamin D supplements may be given to help increase calcium absorption and lower phosphorus levels in the blood.

Choice C reason: Calcium 9.8 mg/dL is a normal value, as the normal range is 8.6 to 10.2 mg/dL. Hypoparathyroidism causes low levels of parathyroid hormone (PTH), which regulates calcium and phosphorus balance in the body. Low PTH leads to low calcium and high phosphorus levels in the blood. However, calcium levels may be normal or near- normal in some cases of hypoparathyroidism, especially if the condition is mild or well-controlled with treatment.

Choice D reason: Magnesium 1.8 mEq/L is a normal value, as the normal range is 1.5 to 2.5 mEq/L. Hypoparathyroidism does not directly affect magnesium levels, but magnesium deficiency can cause or worsen hypoparathyroidism, as magnesium is needed for PTH secretion and action. Magnesium supplements may be given to correct magnesium deficiency and improve PTH function.

Choice A: Negative Chvostek’s sign is the absence of facial twitching when the facial nerve is tapped. This is a normal finding and does not indicate hypoparathyroidism. A positive Chvostek’s sign is a sign of hypocalcemia, which can occur in hypoparathyroidism.

Choice B: Flaccid muscles are weak and limp muscles that lack tone and resistance. This is not a typical finding of hypoparathyroidism, as low levels of parathyroid hormone can cause muscle spasms, cramps, and tetany.

Choice C: Numbness of the hands is a common finding of hypoparathyroidism, as low levels of parathyroid hormone can cause hypocalcemia, which affects the nerve function and sensation. Numbness can also occur in the feet, lips, and tongue.

Choice D: Hypercalcemia is a high level of calcium in the blood. This is not a finding of hypoparathyroidism, as low levels of parathyroid hormone can cause hypocalcemia, which is a low level of calcium in the blood. Hypercalcemia can be a sign of hyperparathyroidism, which is the opposite condition of hypoparathyroidism.
