Certified Dialysis Nurse Practice Test Prep & Study Guide

In patients with chronic kidney disease (CKD), the metabolism of Vitamin D is notably impaired due to the kidneys' reduced ability to convert it to its active form, calcitriol (1,25-dihydroxyvitamin D). The kidneys play a crucial role in the hydroxylation processes that activate Vitamin D; when kidney function declines, this process is significantly affected. As a result, patients with CKD often experience difficulties in maintaining adequate levels of active Vitamin D, which can lead to disturbances in calcium and phosphate metabolism, contributing to bone disease and other complications. Addressing Vitamin D deficiency is vital in managing CKD and preventing secondary hyperparathyroidism, making it a key focus in the care of these patients.
