Question 1

Wound Healing-Three Phases/Stages

Answer 1

FIRST Phase/Stage:Inflammatory phase or (defensive phase or reaction)
Second Phase/Stage: Proliferative Phase or regeneration or reparative phase.
Third Phase/Stage: Remodeling or Maturation

Question 2

The body’s initial reaction to the insult is inflammation. This phase is characterized by edema (swelling), erythema (redness of the skin), heat and pain. This phase typically lasts from 4-6 days, however it can last up to 2 weeks.

Answer 2

FIRST Phase/Stage:Inflammatory phase or (defensive phase or reaction)

Question 3

limit tissue damage, remove injured or damaged cells, and repair the injured tissue. This begins immediately and it’s the body’s defense in righting the wrong.

Answer 3

The inflammatory process functions;

Question 4

______ wounds may or may not be infected, and ______ wounds may or may not be inflamed.

Answer 4

inflamed; infected

Question 5

typically lasts from 4-24 days, however it can last much, much longer depending on what is inhibiting wound healing.

This process involves the body reacting to specifically repair the wound by replacing damaged tissue.

Answer 5

Second Phase/Stage: Proliferative Phase or regeneration or reparative phase.

Question 6

Proliferative Phase/Stage2 major events

Answer 6

Event 1- Granulation Tissue Formation

Event 2- Re-Epithelization

Question 7

Granulation Tissue Formation

Answer 7

Proliferative Stage – Event #1

Question 8

is a collagen matrix which contains different types of cells that contribute to wound healing, such as: endothelial cells, fibroblasts, lymphocytes, platelets, and epidermal cells. This tissue has a red, beefy, shiny, granular appearance. As this type of tissue proliferates, fibroblasts stimulate the ongoing production of collagen. Collagen is what gives tissue it’s tensile strength and ultimately, it’s structure.

Answer 8

Granular Tissue

Question 9

also occurs during the proliferative/regeneration phase, and that is where a new blood supply is generated.

Answer 9

Neovascularization

Question 10

Re-epithelialization

Answer 10

Proliferative Stage – Event #2

Question 11

epithelial margins will begin to migrate toward the center of the wound; This process is sometimes referred to as a “contraction” of the wound… where the surface area of the wound reduces in size. When epithelialization is complete, a scar results.

Answer 11

Re-establishment of an epidermis on top of the granulation tissue;

Question 12

Why don’t we back stage pressure ulcers?

Answer 12

Because it would get too complicated

Question 13

This final phase of wound healing can last from 21 days to 2 years.

Primarily the collagen fibers continue to reorganize, remodel, mature and gain tensile strength.

Answer 13

Phase 3: Remodeling or Maturation Phase/Stage

Question 14

refers to something happening directly within the wound

Pressure:
Dry Environment: Wounds will heal three to five times faster and less painfully in a moist environment than in a dry one. (moist wound healing:

Answer 14

Factors that impede healing:Local

Question 15

Age:  
Body Build:  
Chronic Diseases:  
Nutritional Status:  
Vascular Insufficiencies:  
Immunosuppression and Radiation Therapy:
Other common drugs can impede healing (NSAIDS)

Answer 15

Systemic Factors that Impede Wound Healing: (factors away from the wound)
