Question
A CKD client on calcium acetate develops hypercalcemia. Which provider order would the nurse anticipate?
1Add IV calcium gluconate
2Increase dietary calcium
3Increase calcium acetate dose
4Switch to a non-calcium phosphate binder (sevelamer, lanthanum, ferric citrate)✓ Correct answer
Explanation
Correct (2): Calcium-containing binders (acetate/carbonate) can cause hypercalcemia and vascular calcification in CKD. With elevated Ca, switch to non-calcium binder (sevelamer, lanthanum, ferric citrate, sucroferric oxyhydroxide). (1,3,4) Worsen.
In-depth explanation
Memory Tip Calcium binders = "Cheap but Calcium load." Switch to sevelamer/lanthanum when Ca rises or vascular calcification noted.
Clinical scenario
Scenario 70-year-old female CKD on calcium acetate phosphate binder. New Ca 11.5·constipation. PTH stable.
Key concepts
Calcium acetate/carbonate — Cheap phosphate binders; risk of hypercalcemia and vascular calcification.
Hypercalcemia in CKD — Drug-induced from binders or vitamin D analogs; switch to non-calcium binder.
Vascular calcification — Cardiovascular complication of CKD-MBD; lowered with non-calcium binders.
