← Human Body & HealthIf a child with chronic kidney disease doesn't receive sufficient vitamin D supplementation, which consequence is most likely related to renal osteodystrophy?
A)Increased phosphate absorption
B)Impaired bone mineralization✓
C)Elevated calcitonin secretion
D)Decreased parathyroid hormone
💡 Explanation
Impaired bone mineralization occurs because vitamin D is essential for calcium absorption and deposition in bone. In kidney disease, the kidneys fail to activate vitamin D, therefore leading to reduced calcium and phosphate levels and resulting in rickets/osteomalacia, rather than proper bone formation.
