Certified Dialysis Nurse Practice Test

Bone health is particularly significant for patients undergoing dialysis primarily due to the risk of renal osteodystrophy, a condition that arises from mineral imbalances commonly associated with chronic kidney disease and dialysis. In patients with compromised kidney function, there is an impaired ability to excrete phosphorus, leading to elevated phosphorus levels and a subsequent decrease in calcium levels. This imbalance triggers the parathyroid gland to produce more parathyroid hormone (PTH), which can result in bone demineralization and weakening, manifesting in renal osteodystrophy.

Maintaining bone health is thus crucial for dialysis patients to prevent these complications. Effective management of mineral and bone disorders not only minimizes the risk of fractures and skeletal deformities but also contributes to the overall quality of life. It helps to stabilize mineral balances in the body, which is particularly important for patients who may already be facing numerous health challenges due to their renal condition.

Other options, while they may have some relevance to the overall health of patients, are not as directly linked to the specific issues arising from dialysis-related bone health and mineral imbalances.
