A 58-year-old client with stage 4 chronic kidney disease (CKD) asks the nurse why the primary health care provider restricted dietary potassium. Which explanation best describes the rationale for this dietary restriction?
- The kidneys can no longer adequately excrete potassium, leading to dangerous elevations in serum levels.
- Excess dietary potassium causes fluid retention and peripheral edema.
- Potassium competes with calcium absorption, increasing the risk of renal osteodystrophy.
- High potassium intake worsens proteinuria and accelerates nephron destruction.
