wounds

Question 1

stages of wound healing

Answer 1

haemostasis, inflammatory phase, proliferation, remodeling

Question 2

haemostasis

Answer 2

Vasoconstriction
platelet aggregation
leukocyte migration

Seconds-hours

Question 3

inflammatory phase

Answer 3

Vasodilation to bring WBC to remove foreign body (phagocytosis)
Neutrophils/macrophages

Hours to days

Question 4

proliferation

Answer 4

Extra-cellular matrix and collagen fibre formation
Granulation
Epithelization
(Chronic wound-stage of stasis)

Days to week

Question 5

remodelling

Answer 5

Scar formation
Dermis and epidermis contact
Increase in tensile strength due to extra cellular matrix

week to months

Question 6

epithelialization

Answer 6

always starts from wound edge and works its way in, epithelial cells migrate upwards and repair wounded area

Question 7

granulation tissue

Answer 7

• Highly vascular, new connective tissue and microscopic blood vessels that form on surfaces during the healing process

Question 8

hyper granulation

Answer 8

• Over formation of granulating tissue, fills wound bed and grows beyond wound edge and height of wound surface. Is stuck in proliferation phase

Question 9

necrotic tissue

Answer 9

• Non-viable tissue due to poor blood supply, describes as dry, thick, leathery tissue, tan/brown/black in colour

Question 10

slough

Answer 10

• Liquified dead tissue. Yellow/white tissue in wound bed, usually wet but can be dry

Question 11

eschar

Answer 11

• Hardened necrotic tissue, brown/black/crusty

Question 12

exudate types

Answer 12

serous, sanguineous, serosanguinous, purulent

Question 13

osteomyelitis

Answer 13

• An infection of bone/bone marrow, a Cx condition often seen in diabetic foot ulcers

Question 14

peri wound

Answer 14

tissue surrounding wound

Question 15

wound assessment

Answer 15

Tissue, condition of wound bed, odour, exudate, peri wound, size/length/depth, shape, type (is undermining present), factors impacting wound healing, location, underlying structure involvement

Question 16

arterial leg ulcer

Answer 16

deep pale base with well defined edges
minimal to no hair near
thin, dry and shiny skin
leg may be cool
diminished leg pulses
painful, but eased in dependent position

Question 17

venous leg ulcer

Answer 17

has uneven edges with ruddy granulation tissue
hair on leg
leg may be warm
oedema that may leak and cause maceration
minimal pain, eased by elevated leg
