Question 1

Pitting edema is graded on a 1–4 scale. Grade 3 pitting edema indicates:

Accepted Answer

6 mm depression, rebounds in 1–2 minutes

Answer

Grade 3 pitting edema produces a 6 mm indentation that takes 1–2 minutes to rebound.

Question 2

Which vitamin deficiency is most associated with impaired wound healing?

Accepted Answer

Vitamin C

Answer

Vitamin C is essential for collagen synthesis; deficiency impairs wound healing and can cause scurvy.

Question 3

A full-thickness burn wound is characterized by:

Accepted Answer

White or charred appearance, no pain

Answer

Full-thickness (3rd degree) burns destroy all skin layers including nerve endings, resulting in a painless white, brown, or black appearance.

Question 4

The primary purpose of offloading a diabetic foot ulcer is to:

Accepted Answer

Reduce repetitive mechanical stress to allow healing

Answer

Offloading redistributes pressure away from the wound site, eliminating the repetitive mechanical trauma that prevents healing.

Question 5

Negative pressure wound therapy (NPWT/VAC) promotes healing by:

Accepted Answer

Applying subatmospheric pressure to remove exudate and promote granulation

Answer

NPWT applies controlled negative pressure to remove exudate, reduce edema, and stimulate granulation tissue formation.
