Question 32

What not to debride?

Answer 32

Direct vessels, hypodermis, cutaneous muscle, bone, ligament attached to bone, nerve

Question 33

First Intention

Answer 33

Primary closure within a few hours

Question 34

Third Intention

Answer 34

Delayed primary closure prior to granulation formation

Question 35

Second Closure

Answer 35

After granulation formation

Question 36

Second Intention

Answer 36

Non closure, contraction and epithelialization

Question 37

Epithelialization

Answer 37

Healing of partial thickness wounds

Question 38

Golden Period

Answer 38

Wound treated within 6-8 hours of injury, should not be closed after this period

Question 39

Primary Bandage Layer

Answer 39

Dressing, directly on wound, gauze or mesh, allows fluids to pass

Question 40

Secondary Bandage Layer

Answer 40

Absorbs fluids, pads wound, decreases dead space, supports limb, cast padding or roll cotton

Question 41

Tertiary Bandage Layer

Answer 41

Provides pressure, holds inner layer in place, adhesive tap or elastic wrap

Question 42

Hydrophilic Foam

Answer 42

Maintains moisture, low adherence, high fluid handling capacity

Question 43

Sugar

Answer 43

Used on exudative wounds, decreases bacteria, promotes debridement and granulation

Question 44

Honey

Answer 44

Promotes debridement, granulation, and epithelialization, reduces edema and inflammation

Question 45

Silver

Answer 45

Inflammatory and repair phases, no resistance

Question 46

Antibiotics

Answer 46

Inflammatory and repair phases

Question 47

Enzymatic Agents

Answer 47

Inflammatory phase, slow,

Question 48

Drain Placement

Answer 48

When dead space cant be eliminated, fluid accumulation is likely, infection is present

Question 49

Passive Drains

Answer 49

Relies on gravity or pressure, fluid exits around tube at incision site
