A patient with chronic kidney disease is prescribed oral calcium carbonate with meals. Which purpose should the nurse explain?
Correct answer: A. It binds dietary phosphate in the intestine
- A. It binds dietary phosphate in the intestine
- B. It directly increases erythropoietin production
- C. It dissolves urinary stones in the renal pelvis
- D. It prevents all bacterial infections of the urinary tract
Explanation
Calcium carbonate acts as a phosphate binder when taken with meals, reducing intestinal phosphate absorption. Chronic kidney disease commonly causes phosphate retention because the kidneys cannot excrete it effectively. The drug does not stimulate erythropoietin or treat urinary infection.
