Q

is the period of time required to resolve immediate problems resulting from the injury.

Q

artificial skin (Integra) becomes a permanent structure. Consists of an epidermal and dermal layer

A

dermal substitutes

54
Q

Patient’s own skin is used

A

autografts

55
Q

begins with the mobilization of extracellular fluid and subsequent diuresis. (intravascular fluid deficit)
The acute phase is concluded when the burned area is completely covered by skin grafts, or when the wounds are healed.
Focuses on respiratory and circulatory status

A

acute phase

56
Q
A
57
Q

what are the acute phase manifestations?

A

Partial-thickness wounds form eschar.
Once eschar is removed, re-epithelialization begins.

burn wounds are healed.
client is able to resume a level of self-care activity.

Q

Healthy red tissue is observed and is deposited during the repair process. It presents as pinkish/red colored moist tissue and comprises of newly formed collagen, elastin and capillary networks. The tissue is well vascularized and bleeds easily.

A

granulating

69
Q

is a process by which the wound surface is covered by new epithelium, this begins when the wound has filled with granulation tissue. The tissue is pink, almost white, and only occurs on top of healthy granulation tissue.

Q

Describes a wound containing dead tissue. The wound may appear hard, dry and black. Dead connective tissue may appear grey. The presence of dead tissue in a wound prevents healing.

hyper granulation

73
Q

Wound undermining occurs when the tissue under the wound edges becomes eroded, resulting in a pocket beneath the skin at the wound’s edge

undermining

74
Q

Similar to undermining, however usually occurs in only one direction and can be much deeper

  5. Large/Copious- Saturates entire dressing
76
Q

what are the types of wound edges?

A

Approximation / Dehiscence
Jagged
Wound Edges Attached/Detached
Macerated

77
Q

characteristics of the wound
characteristics of the environment

78
Q

characteristics of the individual

79
Q

Q

Duration of wound, large wound area, deep wound, located near a site of potential contamination (perineum, sacrum)

A

chronic wound

81
Q

Interwoven matrix of bacteria and fungi embedded in a thick slimy barrier of sugars and proteins that begins to form within minutes of skin breakdown.
They are resistant to antibiotics (including topical)
