A nurse is caring for a client who has kidney cancer and has been informed that it has metastasized. Which of the following statements should the nurse make when the client asks what metastasis means?

Choice A reason: Epoetin alfa is used to treat anemia associated with chronic kidney disease, and iron supplementation is often required to support red blood cell production.

Choice B reason: Sodium intake does not need to be increased with epoetin alfa therapy and should be monitored carefully in clients with chronic kidney disease.

Choice C reason: Potassium levels should be monitored in chronic kidney disease and not necessarily increased, as hyperkalemia can be a concern.

Choice D reason: Protein intake should be managed carefully in chronic kidney disease to avoid excess nitrogen waste, which can be difficult for damaged kidneys to filter.

Choice A rationale: Cantaloupe is high in potassium. Clients with acute kidney injury (AKI) have impaired potassium excretion, and consuming high-potassium foods increases the risk of hyperkalemia, which can lead to cardiac arrhythmias.

Choice B rationale: Baked potatoes contain significant potassium, especially in the skin. In AKI, potassium retention is dangerous, so this choice reflects poor understanding of dietary restrictions for renal safety.

Choice C rationale: Yogurt is rich in potassium and phosphorus. In AKI, both electrolytes may accumulate due to reduced renal clearance, making yogurt an inappropriate choice without close monitoring.

Choice D rationale: Pecans are low in potassium, making them a safer snack for clients with AKI. Choosing low-potassium foods demonstrates appropriate understanding of renal dietary management.
