Question 1

Cathode and Anode in woundbed

Answer 1

Cathode (-) directly in wound bed for antibac (attracts neutrophils and depletes bac substrate)

Positive (+) to promote wound healing

Question 2

Burn wound classification: 5 categories

Answer 2

1. SUPERFICIAL-pink/red no blistering (sunburn)
   3-7 days w/out scarring
2. superficial PARTIAL-thickness- Epidermis and upper dermis damaged, moist blisters 7-21 days
3. Deep PARTIAL-thickness burns: slow healing, scarring w/out treatment. white/red waxy moist.
4. FULL thickness- white/grey/charred/black, dry. Skin grafting necessary, hypertrophic scarring likely without prevention.
5. Subdermal burn- Electrical burns, prolonged contact with flame. Extensive surgery/grafting/amputation possible.

Question 3

Stages of pressure ulcers: 4-6 stages

Answer 3

1. Non-blanchable erythema
2. Partial thickness-shallow crater
3. Full thickness-up to fascia-deep crater
4. Full thickness-deeper than fascia
   Unstageable and suspected deep tissue injury

Question 4

Types of Debridement

Answer 4

Autolytic
Enzymatic
Mechanical
Sharp
Surgical

Question 5

Transparent Films

Answer 5

I and II
autolytic
cover hydrogels
*non-absorbative
NOT for infected

Question 6

Hydrocolloids

Answer 6

wafer/paste becomes gelatinous in wound
II and III, protective, autolytic
min to mod absorption-need to change 3-7 days
NOT for infected

Question 7

Hydrogels

Answer 7

partial and full thickness
necrosis and slough, burns/radiation
Rehydration with secondary dressing
min to mod absorption, NOT for infected
change within 48 hrs prevent maceration

Question 8

Foams

Answer 8

partial and full
min to mod exudate
protective, can be secondary or may require sec.
NOT for dry wounds

Question 9

Alginates

Answer 9

Fluffy to gel in wound, can dry wound
mod-max exudate (up to 20x their wt)
necrosis, infected or non-infected

Question 10

Gauze Dressings

Answer 10

Dry for heavy exudative wounds
can be mechanical-wet to dry (painful)
can be autolytic-Wet
Often used with topicals

Question 11

Silver nitrate; nitrofurazone

panafil

Sulfamylon

Answer 11

Silver nitrate and nitrofurazone are superficial agents that attack surface organisms

Panafil is a keratolytic enzyme used for selective debridement

Sulfamylon penetrates through eschar and provides antibac

Question 12

Best dressing for exposed tendon?

Answer 12

calcium alginate. Better if wet so does not dry out tendon.

Question 13

burn victim with claw hand deformity-what position to splint?

Answer 13

this deformity (wrist ext, MCP ext, IP flexion) should be counteres by splinting in a functional slight wrist ext, MCP flexion and IP ext.
