Week 2 Pressure Injuries

Question 1

whoa re the greatest people at risk for pressure injuries

Answer 1

SCI, hospitalized, and long term care patients

Question 2

what causes pressure injuries

Answer 2

pressure! so pathophysiology and intrinsic and extrinsic factors

Question 3

if you increase pressure… your. intracapillary BP…

Answer 3

you increase intracapillary BP and decrease blood flow to soft tissue and obstructed lymph vessels.

Question 4

the decreased flow to soft tissue causes

Answer 4

ischemia

Question 5

if you have increased metabolic waste and acidosis you get

Answer 5

cell death

Question 6

capillary permeability and local edema increases which limits

Answer 6

circulation and leads to necrosis

Question 7

if you decrease fibrinolysis, you get fibrin deposits which leads to

Answer 7

micro thrombi with occludes vessels and leads to more necrosis

Question 8

extrinsic factors that cause PI

Answer 8

amount of pressure 
duration 
friction 
shear 
moisture 
temperature

Question 9

intrinsic facts that cause PI

Answer 9

muscle atrophy, impaired mobility, medications, malnutrition, medical conditions (like impaired semsationand previous pressure ulcers), advanced age

Question 10

locations of PI in supine

Answer 10

posterior heel, sacrum coccyx, SP, medial humeral epicondyle, scapula, occiput

Question 11

locations of the PI in prone

Answer 11

anterior tibia and knee and iliac crest

Question 12

location in S/L

Answer 12

malleoli, medial and lateral femoral condyles, greater trochanter, lateral humeral epicondyle, ear

Question 13

W/C location

Answer 13

sacrum and coccyx and ischial tuberosity and greater trochanter

Question 14

what is stage I

Answer 14

non- blanchable erythema, and localized over a bony prominence and difficult to detect with darker skin

Question 15

what is stage II

Answer 15

partial thickness skin loss with exposed dermis (pink or red wound without slough or granulation tissue)moist.

Question 16

Stage 2 is not

Answer 16

skin tears
dermatitis
maceration

Question 17

Stage 3

Answer 17

full thickness skin loss with adipose exposed and slough may be present. There is undermining, tracts and epibole possible.

Question 18

Stage 4

Answer 18

full thickness skin and tissue loss with exposed bone, tendon or muscle, and may have slough or eschar and undermining and tracts

Question 19

unstageable

Answer 19

may have dark eschar or slough or a combo of both. It is obscured full thickness skin and tissue loss because the base is covered with eschar or slough and true depth can’t be determined

Question 20

what is a DTI

Answer 20

deep pressure injury that is localized area of discoloration with intact or non-intact skin. It is purple or maroon in color, and there is damage to underlying tissue. it is difficult to detect with darker skin tones. THE WOUND HASNT OPENED YET
