Final answer:
Long-term treatment of hyperphosphatemia in patients with renal failure typically includes the administration of calcium supplements to counteract the imbalance of phosphates and calcium in the blood.
Step-by-step explanation:
The nurse expects the long-term treatment of a patient with hyperphosphatemia secondary to renal failure will most likely include calcium supplements. Hyperphosphatemia occurs when there is abnormally increased levels of phosphate in the blood, typically due to decreased renal function. High phosphate levels can lead to hypocalcemia, where calcium levels in the blood are too low. To manage this, calcium supplements can help counteract the imbalance by providing more calcium to the body and helping to bind excess phosphate. The other options, such as fluid restriction, magnesium supplements, and increasing intake of dairy products, are not typically used to directly address the issue of hyperphosphatemia.
