4.   18%

5.     1%

 6.   18% 

10

True or False:

The Rule of Nines is relatively accurate for adults but not for children, due to the relative disproportion of body part surface area. 

True

11

Localized areas of dead skin that can extend to the subcutaneous tissues, through the epidermis and dermis. Stage I is mild, stage IV is extensive and potentially life-threatening. 

Decubitus Ulcers 

12

Decubitus Ulcers is also known as: 

Bed sores, pressure sores or trophic ulcers

14

The following are predisposing factors and complications of Decubitus Ulcers. Except:

  1. loss of pain and pressure sensations
  2. Maximum fat and muscle padding between bony weight bearing prominences and skin
  3. disuse atrophy, malnutrition, anemia and infection
  4. paralysis - lower tone in vascular bed and a decrease in circulatory rate

 

Except: 2

15

What are the treatments of Decubitus Ulcers?

Treatment

•   Stage I and II are treated by regular repositioning [every 2 hours].
•  Stage III and IV require a wound care specialist with treatment ranging from irrigation to debridement and skin grafts.

Calluses

24

What are the treatment for corns and calluses?

 Reduce friction, pumice or chemical peels.


 

25

A mark left on damaged skin after it is healed. Made of collagen fibers. Fills a gap in tissue but is non-functional and contains no follicles or glands. 

Scarring

26

What are abnormal types of scars?

 Keloid and hypertrophic scars

27

Scar that are more common and do not grow beyond the boundaries of the original wound.

Hypertrophic 

28
