1

What occurs during the inflammatory stage of wound healing (4)

1. Hemostasis
2. Phagocytosis
3. Autolysis
4. Fibroblast migration

2

What is hemostasis

Blood clotting due to platelets

3

What is phagocytosis

Breakdown and elimination of foreign substances and bacteria

4

What is autolysis

Breakdown of other cellular debris so it can be removed from the area

5

What is fibroblast migration

Bringing fibroblasts into the area

6

What occurs during the proliferation stage of wound healing (4)

1. Collagen synthesis
2. Angiogenesis
3. Epithelialization
4. Wound contraction

7

What is angiogenesis

Development of new blood vessels

8

What occurs during the maturation stage of healing (2)

1. Collagen lysis
2. Collagen replacement

9

What is collagen lysis

Laying down and breaking apart of collagen

10

True or False:
The 3 stages of wound healing can overlap each other

True

11

What are the factors that impede wound healing (8)

1. Some systemic medications
2. Some topical medications
3. Malnutrition
4. Prolonged pressure or stretch
5. Infection
6. Immunodeficiency
7. Smoking
8. Dryness or necrotic tissue

12

What should you assess about chronic wounds (4)

14

What are 4 types of chronic wounds

1. Pressure sores
2. Arterial insufficiency ulcers
3. Venous insufficiency ulcers
4. Diabetic ulcers

15

What is a pressure sore

Area of local tissue loss due to prolonged tissue compression between boney prominences and external surfaces

16

What are the common locations of pressure sores (5)

1. Sacrum
2. Heels
3. Ischial tuberosity
4. Greater trochanter
5. Malloeli

17

What causes a pressure sore

Compression of tissues reduces blood perfusion in tissues and produces necrosis

Non-blanchable erythema of intact skin

20

What is a stage II pressure sore

Partial thickness skin loss to epidermis, dermis, or both

21

What is a stage III pressure sore

Full thickness skin loss including damage to subcutaneous tissue

22

What is a stage IV pressure sore

Full thickness skin loss with destruction or damage to muscle, bone, or support structures

23

What is an arterial insufficiency ulcer

Area of local tissue loss due to arterial blood supply deficiency

24

What are the common locations of arterial insufficiency ulcers (4)

1. On the foot
2. Over malleoli
3. Toe joints
4. Lateral foot border

25

What causes arterial insufficiency ulcers (3)

1. Arteriosclerosis
2. Arterial occlusion
3. Arterial disruption

26

What is a venous insufficiency ulcer

Area of local blood loss due to deficiency in venous drainage

27
