Skin/pain Flashcards
Why is protein so important for skin integrity?
It slows repair and preserves intravascular volume.
Vitamin C, zinc, and copper are important for the skin in what way?
They are involved in the formation and maintenance of collagen.
What is maceration of the skin?
When the skin seems pruney.
What is denuded skin?
When the skin is starting to breakdown. The epidermis is gone and the skin is now open.
What does a full thickness wound involve?
All of the layers into the subQ tissue.
What does a partial thickness wound involve?
Epidermis and part of the dermis.
What are the 4 wound tissue types and their characteristics?
Epithelialization -pink and DRY
Granulation - red and MOIST
Slough - yellow, rough, and stringy
Eschar - Black, full thickness tissue destruction however may still have pain, wet or dry, soft or hard.
What are the 4 wound healing processes?
Regeneration, primary intention, secondary intention, and tertiary intention. (The last 3 need more intervention)
What is tertiary intention wound healing?
The wound can’t initially be sutured. We have to wait for granulation tissue to fill it up and then we can suture. Most commonly seen when there is an infection s/p surgery.
What kind of wound healing will we see in pressure injuries?
Secondary intention
What are the 3 phases of wound healing?
Inflammatory-cleansing
proliferative- granulation
maturation- epithelialization
What are the 5 types of wound drainage?
Serous, sanguineous, serosanguinous, purulent, purosanguineous exudate.
What are 5 possible complications of wounds?
Dehiscence, fistula, infection, hemorrhage, evisceration.
What are some nursing interventions for wounds?
Irrigating, debridement, caring for drainage device, and dressing.
What are the characteristics of stage 1 PU?
- skin intact
- non blanchable
- possibly painful
- different from adjacent skin
What are the characteristics of a stage 2 PU?
Partial thickness
Skin not intact b/c Blistering means that there is separation within the layers.
Characteristics of a stage 3 PU?
Full thickness SubQ fat may be visible Underlying structures not exposed Slough present May include undermining and tunneling
What is undermining?
Tissue destruction along wound margins
What is tunneling?
Destruction extends from wound base into tissue
Characteristics of stage IV PU?
Full thickness
Exposed underlying structures
Undermining and tunneling
Slough or Eschar
