• 7-Dehydrocholesterol

• Calcifediol

The supply of vitamin D depends on dietary intake and/or exposure

to the ultraviolet rays of the sun for conversion of ___________________

to vitamin D3 (cholecalciferol)

• Calcitriol

• Cholecalciferol

___________ then undergoes hydroxylation in the mitochondria of

kidney tissue.

• Cholecalciferol

• 7-Dehydrocholesterol

• Calcifediol

The most active known form of vitamin D3 in

stimulating intestinal calcium transport

Plays an important role in maintaining bone

health, and low levels of calcium may cause

bone disease

• Calcitriol

  management

Oral administration of Rocaltrol to patients with chronic

renal failure compensates for impaired endogenous

production of calcitriol which is decreased when the

glomerular filtration rate falls below 30 ml/min. What patient type is this?

• osteodystrophy

• post

  menopausal osteoporosis

• Secondary hyperparathyroidism

• Hypoparathyroidism

• Vitamin D dependent rickets

In patients with established post-menopausal

osteoporosis, Rocaltrol® increases calcium absorption,

elevates circulating levels of calcitriol and reduces

vertebral fracture frequency. What patient type is this?

• osteodystrophy

• post

  menopausal osteoporosis

• Secondary hyperparathyroidism

• Hypoparathyroidism

• Vitamin D dependent rickets

Calcitriol corrects biochemical abnormalities,

induces healing of rickets, and restores the rate of

skeletal growth. What patient type is this?

• osteodystrophy

• post

  menopausal osteoporosis

• Secondary hyperparathyroidism

• Hypoparathyroidism

• Vitamin D dependent rickets
