Exam 1 -- 300

Abrasion

partial thickness wound

little bleeding

superficial

approximated

skin edges are closed from surgical incision (suture/staple)

blanchable hyperemia

erythema that turns lighter when pressed, then return back to normal color

blanching

pressure applied, discoloration occurs, then back to normal

debriedment

removal of dead tissue

dehiscence

partial or full separation of wound layers

• if wound heals poorly

epithelialization

new tissue formation

• fill wound with granulation tissue — wound contraction — wound resurfacing

eschar

black, brown necrotic tissue

eviscertaion

total separation of wound layers

• organs spilling out

exudate

fluid from wound

fluctuance

wavy feeling during palpation = fluid filled area

granulation tissue

red/moist tissue made of new blood cells = healing

hemostasis

injured blood vessels constrict, platelets gather to stop bleeding

Friction

skin dragged across coarse surface

induration

hardening/thickening of skin b/c inflammation or infection

laceration

cut/tear with irregular edges from sharp trauma

medical device related pressure injury (MDRPI)

skin/tissue pressed on from medical equipment

medical adhesive related skin injury (MARSI)

erythema or cutaneous abnormality stays for 30+ mins after removal of equipment or adhesive agent

negative pressure wound therapy (NPWT)

treatment for wounds with negative pressure suctioning to facilitate healing

nonblanchable erythema

discoloration does not occur, stays red

pressure injury (decubitus ulcer)

impaired skin b/c unrelieved/prolonged pressure

primary intention

bringing wound edges together

puncture wound

small/circular wound with edges coming toward center

• risk for internal bleeding + infection

purulent

thick yellow/green/tan/brown drainage

• indicates possible infection

reactive hyperemia

physiological response to increased blood flow after reduced blood supply

ischemia

reduced blood supply

sanguineous

indicates active bleeding — bright red

secondary intention

wound heals naturally from base, upwards

• no direct surgical closure

serosanguineous

pain/pink watery mix OR clear and red fluid

serous

clear, watery plasma

• normal

shearing

body moving downwards, one point moving upwards

slough

yellow/white tissue in wound bed

tissue ischemia

pressure exceeds normal limit of capillary pressure and vessel blocked for long time

vacuum assisted closer (VAC)

device helps close wound with localized negative pressure

wound

break in skin - disturbs function of tissue

wound drainage evacuators

portable unit connect tubular drains (in wound) to exert low pressure vacuum to remove drainage

ecchymosis

bruising

cyanosis

blue

ashen

grey undertones

jaundice / icterus

yellow

hematoma

larger + deeper bruise

petechiae

pinpoint, flat red spots p

purpura

larger than petechiae but smaller than bruise

purle/red
