NUR 205 EXAM 2 With Complete Correct Answers
Largest Organ of the body - ANSWER The Skin
Two layers of the skin - ANSWER Epidermis and Dermis
Epidermis - ANSWER top layer of skin
Stratum Corneum - ANSWER Outermost layer of the epidermis, which consists of
flattened, keratinized cells
Define Pressure Ulcers - ANSWER Described as impaired skin integrity related to
unrelieved, prolonged pressure, usually over a boney prominence
Pressure Ulcer Risk Factors - ANSWER -decreased mobility
-decreased sensory perception
-fecal or urinary incontinence
-poor nutrition
Individuals at risk for pressure ulcers - ANSWER -older adults that have experienced a
trauma
-those with spinal cord injuries
-those who have sustained a fractured hip
-those in long-term homes or community care, the acutely ill
-individuals with diabetes
-patients in critical care settings (ICU)
, Dermis - ANSWER inner layer of skin, provides tensile strength, mechanical support, and
protection for the underlying muscles, bones, and organs
Tissue Ischemia - ANSWER Pressure applied over a capillary exceeds the normal capillary
pressure, and the vessel is occluded for a prolonged period of time.
dermal-epidermal junction - ANSWER separates dermis and epidermis
3 pressure related factors that contribute to pressure ulcer development - ANSWER
-pressure intensity
-pressure duration
-tissue tolerance
Non-blanchable hyperemia - ANSWER redness that persists after palpation and indicates
tissue damage
Stage 1 Pressure Ulcer - ANSWER -intact skin with nonblanchable redness
-warm to touch, edema, can be a hardened area
Stage 2 Pressure Ulcer - ANSWER -partial thickness skin loss
-shallow but open
-no slough or drainage
-red/pink wound bed
Stage 3 Pressure ulcer - ANSWER -full thickness tissue loss with visible underlying fat
