To assist in the healing of a large leg ulcer, the nurse applies wet dressings to the wound to promote
a. angiogenesis.
b. chemotaxis.
c. epithelialization.
d. wound contraction.
C
Wound healing is optimized in a moist environment. When the environment is moist, collagen synthesis and granulation tissue formation are enhanced, cell migration and epithelial resurfacing occur more rapidly, and scab, crust, and eschar cannot form. Angiogenesis is the formation of new blood vessels. Chemotaxis is the movement of cells in relation to a chemical stimulation. Wound contraction can cause scarring and deformity.
