1. Stages of wound healing Ans: Inflammatory Stage
Proliferative Stage
Maturation or Remodeling Stage
2. Inflammatory Stage Ans: Begins with the injury and lasts 3 to 6 days
3. Inflammatory stage effects to the wound Ans: Controlling bleeding with vasocon-
striction, retraction of blood vessels, fibrin accumulation, and clot formation.
Delivering oxygen, WBCs, and nutrients to the area via the blood supply. Macrophages
engulf micro-organisms and cellular debris (phagocytosis). This phase is prolonged when
there is too little inflammation (with debilitating disease), or when there is too much
inflammation.
4. Proliferative Stage Ans: Lasts the next 3 to 24 days
5. Proliferative stage effects to the wound Ans: Replacing lost tissue with connective or
granulated tissue and collagen.
Contracting the wound's edges to reduce the area that requires healing.
Resurfacing of new epithelial cells.
6. Maturation or Remodeling Stage Ans: Occurs on or about day 21 and involves the
,strengthening of the collagen scar and the restoration of a more normal appearance. It can
take more than 1 year to complete, depending on the extent of the original wound.
7. Healing Processes Ans: Primary Intention
Secondary Intention
Tertiary Intention
8. Primary intention healing Ans: Little or no tissue loss
Edges approximated, as with a surgical incision Heals
rapidly
Low risk of infection No
or minimal scarring
, 9. Example of primary intention healing Ans: Closed surgical incision with staples,
sutures, or liquid glue to seal laceration
10. Secondary intention healing (1-3) Ans: Loss of tissue
Wound edges widely separated, unapproximated (pressure injury, open burn areas).
Longer healing time
11. Secondary intention healing (4-6) Ans: Increase for risk of infection
Scarring
Heals by granulation
12. Example of secondary intention healing Ans: Pressure injury left open to heal
13. Tertiary intention healing (1-4) Ans: Widely separated
Deep
Spontaneous opening of a previously closed wound.
Closure of wounds occurs when they are free of infection and edema.
14. Tertiary intention healing (5-8) Ans: Risk of
infection Extensive drainage and tissue debris
Closed later
Long healing time
