Certified Dialysis Nurse Practice Test

Calcium plays a crucial role in managing dialysis patients, particularly in terms of bone health and cardiovascular issues. Patients undergoing dialysis often have altered calcium and phosphate metabolism due to kidney failure, which can lead to various complications, including bone disease known as renal osteodystrophy. This condition occurs when the kidneys are unable to excrete phosphate effectively, leading to an imbalance that can cause bone demineralization.

Maintaining proper calcium levels is essential because calcium works in tandem with phosphate to support bone strength and integrity. Additionally, calcium has significant implications for cardiovascular health; low calcium levels can contribute to vascular calcification, a common issue in dialysis patients. Managing calcium levels through dietary adjustments, supplements, or medications is vital for preventing the adverse effects of mineral imbalances.

While other options touch upon important health aspects, they do not specifically highlight the dual importance of calcium for both bone and cardiovascular health in the dialysis context, making the alignment of choice B with the physiological needs of dialysis patients particularly relevant.
