Question 9

erythema

Answer 9

redness of the skin

Question 10

eschar

Answer 10

thick, leathery scab or dry crust that is necrotic and must be removed for adequate healing to occur

Answer 13

an abnormal passage from an internal organ to the skin or from one internal organ to another

Question 14

overhydration

Question 19

necrosis

Answer 19

death of cells and tissue

Question 20

negative pressure wound therapy (NPWT)

Answer 20

activity that promotes wound healing and wound closure through the application of uniform negative pressure on the wound bed, reduction in bacteria in the wound, and the removal of excess wound fluid

Question 21

pressure injury

Answer 21

(1) localized damage to the skin and underlying tissue that usually occurs over a bony prominence or is related to the use of a (medical or other) device; (2) any lesion caused by unrelieved pressure that results in damage to underlying tissue; formerly known as pressure ulcer

Question 22

purulent drainage

Answer 22

comprised of white blood cells, liquefied dead tissue debris, and both dead and live bacteria

sanguineous drainage

Answer 23

containing or mixed with blood

serous drainage

Answer 26

composed of clear, serous portion of the blood and from serous membranes

Question 27

shear

Answer 27

force created when layers of tissue move on one another

Question 28
