Veterinary IV CFE Practice Test

Which nutritional factor supports remodeling phase of wound healing?

Vitamin E Vitamin A Vitamin D Vitamin K

Correct Answer:

Vitamin A

Explanation:

Remodeling phase relies on collagen maturation and rebuilding tensile strength, and adequate Vitamin A supports these processes. Vitamin A promotes fibroblast activity and collagen synthesis, helping lay down and organize the matrix more effectively. It also aids epithelialization and helps modulate the inflammatory environment to avoid prolonged inflammation that can impair remodeling. This combination—enhanced collagen production, better epithelial repair, and balanced inflammation—facilitates the transition from the immature scar to stronger, organized tissue. The other vitamins don’t have as direct an influence on this remodeling-oriented maturation of the wound matrix.
