28
Q

Epibole

A

Rolled edge of the wound margin due to reattachment of the skin to itself

29
Q

Epidermis

A

The outer cellular layer of the skin (0.6mm)

30
Q

Epithelialization

A

Regeneration of the epidermis across the wound surface

31
Q

Erythema

A

Redness of the skin surface produced by vasodilatation

32
Q

Eschar

A

Thick, leathery scab or dry crust composed of dead cells and dried plasma

33
Q

Excoriation

A

Linear scratches on the skin

34
Q

Exudate

A

A mixture of fluid, protein and cells in the wound

35
Q

Fibroblast

A

Any cell from which connective tissue is developed

36
Q

Friction

A

Surface damage caused by skin rubbing against another surface

37
Q

Full-thickness

A

Tissue destruction extending through the dermis to involve the subcutaneous layer and possible muscle or bone

38
Q

Granulation

A

The formation or growth of small blood vessels and connective tissue in a full- thickness wound.

39
Q

Hemosiderin

A

Staining from iron rich pigment that is a product of red cell hemolysis

40
Q

Hydrophilic

A

Attracting moisture

41
Q

Hydrophobic

A

Repelling moisture

42
Q

Hyperemia

A

Presence of excess blood in the vessels; engorgement

43
Q

Infection

A

Overgrowth of microorganisms capable of tissue destruction and invasion accompanied by systemic symptoms

44
Q

Inflammation

A

Defensive reaction to tissue injury; involves increased blood flow and capillary permeability and facilitates physiologic cleanup of the wound.

Accompanied by increased heat, redness, swelling and pain in the affected area

45
Q

Induration

A

Hardness at wound edges

46
Q

Intermittent Claudication

A

Pain in lower extremities when walking short distances due to arterial insufficiency.

47
Q

Ischemia

A

Loss of blood to an area due to constriction or obstruction of a blood vessel.

48
Q

Leukocytosis

A

Increase in the number of leukocytes in the blood

49
Q

Lymphedema

A

A condition in which extra lymph fluid builds up in tissues and causes swelling.

It may occur in an arm or leg if lymph vessels are blocked, damaged, or removed by surgery

50
Q

Maceration

A

Softening of the tissue caused by excessive moisture or soaking in fluids

51
Q

Macrophage

A

Cells which have the ability to destroy bacteria and necrotic tissue

52
Q

Necrotic

A

Dead; avascular.

53
Q

Partial-thickness

A

Loss of epidermis and possible partial loss of dermis.

54
Q

Periwound

A

Tissue surrounding a wound.

55
Q

Prevalence

A

Prevalence measures all cases of a condition (e.g., pressure ulcers) among those at risk for developing the condition. Measures of prevalence are made at one point in time such as a specific day

56
Q

Pressure ulcer

A

Area of localized tissue damage caused by ischemia due to pressure

57
Q

Purulent

A

Thick fluid indicative of infection containing leukocytes, bacteria, and debris.

58
Q

Sanguinous

A

Bloody drainage from a wound.

59
Q

Serous

A

Fluid that has characteristics of serum; is clear

60
Q

Serosanguinous

A

Fluid drainage with a bloody tint

61
Q

Shear

A

Trauma caused by tissue layers sliding against each other resulting in disruption or angulation of blood vessels.

62
Q

Sinus tract

A

Pathway extending in any direction from the wound and resulting in dead space with potential for abscess formation.

63
Q

Slough

A

Loose, stringy necrotic tissue.

64
Q

Tunneling

A

Pathway extending in any direction from the wound with an entry and exit point

65
Q

Undermining

A

Tissue destruction underneath intact skin along wound margins

66
Q

Wound base

A

Upper layer viable tissue in the wound; may be covered with slough or eschar

67
Q

Wound margin

A

Rim or border of wound.

68
Q

Wound repair

A

Healing process. Partial-thickness involves epithelialization; full-thickness involves granulation, epithelialization and contraction.

69
Q

Wet gangrene

A

Boggy eschar, often a gray color.
