Q

induration

A

hardening of a tissue, particularly the skin, because of edema or inflammation

17
Q

laceration

A

torn, jagged wound

18
Q

medical adhesive-related skin injury (MARSI)

A

the presence of erythema and/or other manifestation of cutaneous abnormality that persists 30 minutes or longer after removal of a device or adhesive securing the device

19
Q

medical device-related pressure injury (MDRPI)

A

occurs when the skin or underlying tissues are subjected to sustained pressure or shear from medical devices or equipment

20
Q

negative-pressure wound therapy (NPWT)

A

vacuum-assisted closure; the application of subatmospheric pressure to a wound through suction to facilitate healing and collect wound fluid

21
Q

nonblanchable erythema

A

when the color of a pressure injury remains the same when pressure is applied to it

22
Q

pressure injury

A

inflammation, sore, or ulcer in the skin over a bony prominence

23
Q

primary intention

A

primary union of the edges of a wound, progressing to complete scar formation without granulation

24
Q

puncture wound

A

a small, circular wound with edges coming together towards the center

25
purulent
thick yellow, green, tan, or brown drainage from a wound
26
sanguineous
a wound drainage showing bright red spot surrounded by light red stain; indicates active bleeding
27
secondary intention
wound closure in which the edges are separated; granulation tissue develops to fill the gap; and, finally, epithelium grows in over the granulation, producing a larger scar than results with primary intention
28
serosanguineous
a wound drainage shows pale red and pink fluid completely staining the gauze
29
Serous
a wound drainage shows light colored circular spot with clear, watery plasma
30
shearing force
force exerted against the skin while the skin remains stationary and the bony structures move
31
slough
soft yellow or white stringy substance attached to wound bed
32
tissue ischemia
point at which tissues receive insufficient oxygen and perfusion
33
vacuum-assisted closure (V.A.C.)
a device that helps in wound closure by applying localized negative pressure to draw the edges of a wound together
34
wound
a disruption of the integrity and function of tissues in the body
35
wound drainage evacuators
convenient portable units that connect to tubular drains lying within a wound bed and exert a safe, constant, low-pressure vacuum to remove and collect drainage
