What is the average range of calcium concentration in dialysis patients?

1.5-2.5 mEq
2.0-3.0 mEq
2.5-3.5 mEq
3.0-4.0 mEq

The correct answer is: 2.5-3.5 mEq

The average range of calcium concentration in dialysis patients typically falls between 2.5 to 3.5 mEq/L. This range is crucial for managing patients with chronic kidney disease, as they often experience disturbances in calcium metabolism due to the kidneys' reduced ability to regulate mineral levels. Maintaining calcium within this range helps prevent complications such as bone disease and cardiovascular issues, which are common in dialysis patients. The selected range reflects the balance needed for proper physiological functions, including bone health and neuromuscular activity. Maintaining calcium levels within this concentration ensures optimal health and minimizes the risk of both hypocalcemia (low calcium levels) and hypercalcemia (high calcium levels), which can lead to serious health issues. In contrast, the other ranges either exceed or fall below the established average for dialysis patients, indicating either excessive calcium which could lead to complications like calcifications or deficient levels which could cause bone resorption and other metabolic issues. Hence, the correct choice confirms an understanding of calcium management in the context of dialysis care.
