skin func

contusion
blow from a blunt instrument
abrasion
surface scrape
laceration
tissues torn apart; open wound
penetrating
like a bullet or metal fragments
wounds classifed by depth
- partial thickness wounds -skin
- full-thickness wounds- involving thickness
ischemia
deficiency in the blood supply to the tissue
reactive hyereia
skin takes a bright red flush when pressure is relieved
shearing
pressure and friction (so a risk factor for pressure ulcer)
edema
makes it more prone to injury because of the decrease in elasticity, resilience, and vitality
suspected deep tissue injury
purple or maroon discoloured intact skin or blood filled blister
stage 1
nonblanchable reddness
stage 2
shallow open ulcer, serum filled blister
stage 3
full thickness tissue loss. sub fat may be visible
stage 4
exposed bone, tendon or muscle.
a total of — points on the braden scale is possible and anything lower than – is considered at risk

skin tears
are the result of blunt trauma, shearing, or friction
primary intention healing
occurs when the tissue surfaces have been approximatedand minimal or no tissue loss has occured
secondary intention healing
a wound that is extensive an invloves considerable tissue loss and in which the edges cannot or should not be aproximated
phases of healing
- imflamm stage- hemostasis
- proliferative stage- fibroblasts and collagen make tissue
- maturation- scab
exudate
fluid and cells that escaped from the blood vessels during the inflamm stage
dehiscence
is the partial or total rupturing of a sutured wound.
evisceration
the potrusion of the internal viscera through an incision,
lab data
leukocyte (infection) hemoglobin (poor oxygen to tissues) blood coagulation (blood loss) serum protein ( bodys nutritional reserves for rebuilding cells) wound cultures (
