Question

Chronic kidney disease (CKD) can cause derangement of calcium and phosphate metabolism. The nurse will monitor a client with CKD for which lab abnormality? Select all that apply.

a) Hypercalcemia
b) Hypocalcemia
c) Hyperphosphatemia
d) Hypophosphatemia

Answer 1

In CKD, nurses should monitor for hypocalcemia and hyperphosphatemia, as these are common due to reduced renal function and vitamin D3 deficiency.

Step-by-step explanation:

Patients with chronic kidney disease (CKD) often experience disruptions in the metabolism of calcium and phosphate, leading to certain lab abnormalities. The nurse would monitor a client with CKD for hypocalcemia, which is an abnormally low blood level of calcium, and hyperphosphatemia, or abnormally increased blood phosphate levels. Both conditions can arise due to reduced renal function that is characteristic of CKD. In CKD, there is reduced phosphate excretion which can lead to hyperphosphatemia, and this is often associated with hypocalcemia due to a deficiency in vitamin D3, which is necessary for calcium absorption. Therefore, the correct answers are b) Hypocalcemia and c) Hyperphosphatemia.
