Sample item

Which nutrient deficiency particularly impairs collagen hydroxylation and wound healing?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Vitamin C deficiency

Vitamin C is required for proline and lysine hydroxylation during collagen synthesis. Deficiency causes poor wound healing and fragile capillaries.

Option by option

  • A. Vitamin D excess

    Vitamin D excess is not the collagen-hydroxylation defect.

  • B. Vitamin B12 deficiency

    B12 deficiency causes megaloblastic anaemia and neuropathy.

  • C. Vitamin K excess

    Vitamin K is involved in coagulation-factor carboxylation.

  • D. Vitamin C deficiency (correct)

    Correct. Ascorbate is essential for stable collagen formation.
