Answer
Traumatic partial skin avulsion from an extremity, like peeling a glove.
4
Question
What is eschar?
Answer
Hardened necrotic tissue over a wound, attached to wound bed.
5
Question
What is moist wound healing?
Answer
Maintaining moist conditions to promote epithelial migration and granulation.
6
Question
What is myiasis?
Answer
Infection with fly larvae in tissue.
7
Question
When are adherent (wet-to-dry) bandages used?
Answer
Early contaminated wounds within 72 hours, during inflammatory phase.
8
Question
How do adherent (wet-to-dry) bandages work?
Answer
Hydrate wound, then adhere and strip away necrotic tissue upon removal.
9
Question
When should we avoid using adherent bandages?
Answer
Wounds older than 72 hours or with granulation tissue.
10
Question
What is the purpose of non-adherent bandages?
Answer
Prevent sticking to healthy, dry wounds for easy removal.
11
Question
How do non-adherent bandages work?
Answer
Treated fabric prevents sticking, allows exudate passage, becomes semiocclusive.
12
Question
When are non-adherent bandages contraindicated?
Answer
Heavily contaminated or infected wounds.
13
Question
What is the purpose of absorptive bandages?
Answer
Withdraw and retain wound exudate for autolytic debridement.
14
Question
How do absorptive bandages work?
Answer
Retain fluids, promote natural debridement, decrease with granulation tissue formation.
15
Question
When should absorptive bandages not be used?
Answer
Low exudate wounds or highly infected, necrotic wounds.
16
Question
What are semiocclusive bandages used for?
Answer
Protection over minimally exuding wounds, allow moisture vapor passage.
17
Question
How do semiocclusive bandages work?
Answer
Block contaminants, let water vapor escape, no absorption.
18
Question
When should we avoid using semiocclusive bandages?
Answer
In infected wounds.
19
Question
What is the purpose of occlusive bandages?
Answer
Create a sealed environment, retain cytokines, promote healing.
20
Question

Answer
Impermeable outer membrane retains exudate and cytokines, stimulates healing.
21
Question
When should we avoid using occlusive bandages?
Answer
In infected wounds.
22
Question
What is the purpose of moisture-retaining bandages?
Answer
Maintain a moist environment to facilitate autolytic debridement.
23
Question
How do moisture-retaining bandages work?
Answer
Keep tissue hydrated, soothe, and may have absorptive properties.
24
Question
When should moisture-retaining bandages not be used?
Answer
Early in healing, infected, or excessively necrotic wounds.
25
Question
What are the seven Halsted's Principles?
Answer
Gentle tissue handling, meticulous hemostasis, obliteration of dead space, minimal tension, preservation of blood supply, aseptic technique, accurate tissue apposition.
26
Question
What are the four main wound classification types?
Answer
Clean, clean contaminated, contaminated, dirty.
27
Question
What defines a clean wound?
Answer
Nontraumatic, noninflamed, no entry into GI, respiratory, GU or oropharyngeal tracts.
28
Question
What infection rate is typical for clean wounds?
Answer
2-5%.
29
Question
What characterizes a clean contaminated wound?
Answer
Entry into GI, respiratory, GU, or oropharyngeal tracts without contamination or with drain placement.
30
Question
What is the infection rate for clean contaminated wounds?
Answer
3.5-4.5%.
