the wound is clean

Question 6

3 phases of healing

Answer 6

inflammatory
granulation
contraction & epithelialization

Question 7

In the inflammatory process,

Answer 7

clot provides scaffolding for new matrix and migration of cells.

Question 8

Phagocytic cells will

Answer 8

debride wound (remove dead, contaminated, or adherent tissue and/or foreign material)

Question 9

granulation cannot proceed until

Answer 9

blood clots, necrotic tissue and infection have been eliminated

Question 10

Granulation tissue develops for ___________ and continues

Answer 10

3-6 days post injury
until epithelialization (wound closure) occurs

Question 11

Process of contraction and epithelialization

Answer 11

cells migrate centripetally.

Question 12

Healing epithelium is

Answer 12

fragile and poorly adherent to underlying tissues

Question 13

granulation tissue:

Answer 13

provides surface for epithelialization
is resistent to infection
is necessary for wound contraction

Question 14

Factors that affect healing

Answer 14

1. location
2. infection
3. movement
4. wound dimensions
5. involvement of deep structures
6. poor blood or oxygen supply
7. foreign bodies
8. nutrition
9. previous treatment
10. age of wound
11. economics

Question 15

What sorts of foreign bodies may be in a wound?

Answer 15

sand, wood, dirt, necrotic tissue, hair

Question 16

Why do wounds on lower limbs heal more slowly?

Answer 16

decreased vascular supply, bone provinces, no supporting deep musculature, highly mobile joints, higher degree of contamination

Question 17

Wounds will not heal if they are

DRY

Question 18

Wound management steps

Answer 18

infection, skin loss, tension in suture line, marked swelling

Question 20

Initial cleaning procedure:

Answer 20

wash wound with saline or water
cover with hydrogel before clipping
clean wound with 0.5% Chlorhexidine
