A home health nurse is visiting a 58-year-old client with stage 4 chronic kidney disease (CKD). The client asks why the primary health care provider restricted dietary potassium. Which explanation by the nurse is most accurate?
- The kidneys can no longer effectively excrete excess potassium, leading to dangerous cardiac dysrhythmias.
- Excess dietary potassium increases the workload on the kidneys and speeds up disease progression.
- Elevated potassium levels cause fluid retention, which worsens the client's existing edema.
- High potassium intake accelerates the loss of calcium from bones, increasing fracture risk.
