Q

What are some characteristics of the epidermis ?

A
  • outermost layer
  • cells are flattened and dead
  • protects underlying cells and tissues from dehydration
  • prevents entrance of certain chemical agents
  • allows evaporation of water from the skin
  • permits absorption of certain topical medications

Q

What is tissue ischemia ?

A

23
Q

What is eschar ?

A

thick layer of dead, dry tissue that covers a wound bed

24
Q

What is exudate ?

A

fluid, cells, or other substances that have been discharged from cells or blood vessels (think drainage from wound)

25
Q

What is a primary intention in wound healing ?

A

no loss of tissue (clean cut/ surgical incision)
- sutures
- glue
- steri strips

26
Q

What is a secondary intention ?

A

loss of tissue (pressure ulcers)
- infection
- foreign material
- dead tissue

27
Q

What is a laceration ?

A

deep skin cut

28
Q

What is a abrasion ?

A

scrapping injury
- like a scrapped knee

29
Q

What is a puncture wound ?

A

like being poked or “stabbed”

30
Q

What do you assess in a wound assessment ?

A
  • bleeding/drainage
  • foreign bodies/contamination
  • size depth (L/W/D, units of measure, describing location like face of clock)
  • odor
  • characteristics of tissues (wound bed and surrounding)
31
Q

What are some causes of a hemorrhage ?

A
  • slipped suture
  • dislodged clot
  • infection
  • erosion of blood vessel
32
Q

What are some signs/symptoms of a hemorrhage ?

A
  • internal: swelling, distension, hematoma, hypovolemic shock
  • external: obvious ! (risk is higher in first 24-48 hrs)
33
Q

What are some interventions of a hemorrhage ?

A
  • apply pressure/dressing
  • if internal, notify MD for possible OR
34
Q

What do you do if you have wrapped a hemorrhage in a dressing ?

A
  • don’t want to remove this because you could remove any clotting that is starting to happen
  • apply more dressing and mark it so you can notice any further change
35
Q

What are some causes of infection ?

A
  • contaminated wounds
  • SSI
  • foreign body in wound
36
Q

What are some signs/symptoms of infection ?

A
  • purulent drainage
  • fever
  • increased WBC
  • erythema
  • pain/tenderness
37
Q

What are some interventions of infections ?

A
  • topical and IV antibiotics
  • wound irrigation/cleaning solutions
38
Q

What are some characteristics of serous drainage ?

A

clear/watery plasma

39
Q

What are some characteristics of serosanguineous drainage ?

A

pale, pink, watery

40
Q

What are some characteristics of sanguineous drainage ?

A

bright red/active bleed

41
Q

What are some characteristics of purulent drainage ?

A

thick, yellow, green, tan, brown

42
Q

What does dehiscence mean ?

A

partial or total separation of wound layers

43
Q

What does evisceration mean ?

A

with total separation of wound the visceral organ protrudes through the wound opening (when the organs start to come out)
- surgical emergency
- cover with damp/sterile gauze, NPO, contact surgery

44
Q

What does dead space mean ?

A

open space that needs dressing and attention to

45
Q

What does moist dressing mean ?

A

put just enough onto the hurt skin that needs it and now on the skin that doesn’t need it cause then that healthy skin can start to breakdown

46
Q

What is debridement ?

A

removal of nonviable, necrotic tissue
- wet to moist dressings1

47
Q

What is hydrocolloid ?

A

protects the wound from surface contamination

48
Q

What is hydrogel ?

A

maintains a moist surface to support healing
- for necrotic and infection
- swells on contact with exudate

49
Q

What is a wound vacuum assisted closure (VAC) ?

A

uses negative pressure to support healing

50
Q

What do you asess when packing a wound ?

A
  • assess size, depth, and shape
  • do not pack too tightly
  • do not let packing contact intact skin
51
Q

How do you clean skin/incisions/drains ?

A
  • least contaminated to most contaminated
  • gentle friction
  • when irrigating, allow the solution to flow from the least to the most contaminated area
