Skin Integrity and Wound Care (Vocabulary) Flashcards
injury to skin and/or underlying tissue, usually over bony prominence.
CAUSED by force alone or combination of movement
pressure ulcer
a.k.a: decubitus ulcers, pressure sores, bedsores
deficiency in blood supply to tissue
ischemia
bright red flush color skin takes on when pressure ulcer is relieved
reactive hyperemia
extra blood floods into area to compensate for preceding period of impeded blood flow
vasodilation
combination of friction and pressure
shearing force
reduction in amount and control of movement a person has
immobility
tissue softened by prolonged wetting or soaking
CAUSED by incontinence
maceration
area of loss of superficial layers of the skin
excoriation
renewal or healing of tissue
regeneration
tissue that is “closed” is said to be:
approximated
Tissue surfaces have approximated and there is minimal or no tissue loss. Formation of minimal granulation tissue and scarring
Primary intention healing
Extensive wound that involves considerable tissue loss. Edges cannot or should not be approximated
Secondary intention healing
Wounds left open for 3-5 days to allow edema or infection to resolve or exudate to drain and then closed with sutures, staples or adhesive closures
Tertiary intention
Cessation of bleeding when vasoconstriction of larger blood vessels occurs, injured blood vessels retract, deposition of fibrin and blood clots form
Hemostasis
Connective tissue
Fibrin
Cellular debris and microorganisms are engulfed
Phagocytosis
White protein adding tensile strength to wound
Collagen
Young fragile connective tissue with new capillaries formed in wound healing
Granulation tissue
Wound becomes covered with dried plasma proteins and dead cells (necrosis) called
Eschar
Abnormal amount of collagen is laid down creating a hypertrophic scar called
Keloid
Fluids and cells that have escaped from blood vessels during the inflammatory phase and deposited on tissue or cell surfaces
Exudate
Clear portion of blood exiting wound
Serous exudate
Thicker discharge, because it contains pus, exiting wound Varying in color.
Purulent exudate
Pooled exudate containing liquified dead tissue debris, & dead and living bacteria
Pus
