aerobic
growing only in the presence of oxygen
anaerobic
growing only in the absence of oxygen
approximated
closed
Bandage
a strip of cloth used to wrap some part of the body
Binder
a type of bandage designed for a specific body part or to support large areas
collagen
whitish protein substance that adds tensile strength to the wound
compress
a moist gauze dressing applied to a wound
debridement
removal of the necrotic material
dehiscence
the intial translucent, fragile tissue that forms during the proliferative phase of wound healing
eschar
a wound covering of dried plasma proteins and dead cells that occurs if the wound does not close by epithelialization
evisceration
protusion of the internal viscera through an incision
excoritation
area of loss of the superficial layers of the skin
exudate
material that has escaped from blood vessels during the inflammatory process and is deposited in the tissue or on tissue surfaces
fibrin
connective tissue
friction
a force acting parallel to the skin surface
granulation tissue
the initial translucent, fragile tissue that forms during the proliferative phase of wound healing
hematoma
a localized collection of blood underneath the skin that may appear as reddish-blue swelling
hemorrhage
massive bleeding
hemostasis
cessation of bleeding
immobility
reduction in the amount and control of the movement a person has
ischemia
deficiency in the blood supply to the tissue
keloid
kypertrophic scar
maceration
tissue softened by the prolonged wetting or soaking
packing
guaze use to absorb exudate in a wound dressing
phagocytosis
the process which during which macrophages engulf cellukar debris and microorganisms
pressure
compression of tissue
pressure ulcers
result of localized tissue ischemia caused y unrelieved pressure
primary intention healing
occurs where the tissue surfaces have been aproximated, and there is minimal or no tissue loss
puruent exudate
thicker, yellow, blue or green tinged exudate
pus
consists of leukocytes liquified dead tissue debris dead and living bacteria
reactive hyperemia
red flush of sin that occurs when pressure is relieved from an area
regeneration
renewal or healing of the tissue
sauguinous exudate
bloody
secondary intention healing
occurs in a wound that is extensive and the edges cannot be approximated
serosanguinous
mixed drainage consisting of clear and blood-tinged material
serous exudate
clear, watery drainage
shearing force
combination of friction and pressure
sitz bath
used to soak a clients perineal or rectal area
suppuration
the process of pus formation
tertiary intention
wounds left open for 3-5 days, then surgically closed
vasoconstriction
decreased blood flow to an area can be caused by decreased temperature of tissue
vasodilation
the process in which extra blood flows into the area
the sin is the largest orga in the body and serves a variety of important functions in maintaining health and protecting the individual from injury.True or false?
true
hypoproteinema is an abnormaly high protein content in the blood. True or False?
false. hyperproteinema is the answer.
wound beds that are too dry or disturbed too often fail to heal. True or false?
True
Any at risk client confined to bed,even when a special support mattress is used, should be repositioned atleast every 2 hrs depending on the clients needs t allow another body surface to bear the weight. true or false?
True
Moisture from incontinence promotes skin _______ and makes the epidermis more easily eroded and suseceptible to injury.
maceration
wound ______ involves the removal of debris(ie. foreign materials, excess slough, necrotic tissue, bacteria and other microorganisms)
cleansing
Using _____ syringes instead of bulb syringes to irrigate a wound reduces the risk of aspirating drainage and provides safe, effective pressure.
