NURS 312: Integumentary questions well
answered to pass (2025)
1. three layers of -epidermis
the skin -dermis
-subcutaneous (hypodermis)
2. the skin is... -the largest most versatile body organ
-covers entire body surface
-surface area ranges from 1.5 m2 to 2 m2
-weight = 4kg, 9Ibs
3. the skin provides -protection against pathogens
-sensation of touch
-retains body heat
-retains fluids
-retains electrolytes
-produces vitamin D -> needed for calcium intestinal absorption
4. pressure ulcers -etiology: ischemic lesions of skin and underlying structures
-unrelieved pressure that impairs blood and lymph flow
-contributing factors: increased length of stay, increased age,
increased body mass index (obesity), shearing forces and friction,
skin moisture, vasopressor infusion, spinal cord injury
-flip the Q2H
5. stage 1 -persistent redness with intact skin
pressure ulcer
-skin is unbroken but inflamed
6. stage 2
-partial thickness loss of skin
pressure ulcer
-involves epidermis and dermis
-skin is broken to epidermis or dermis
7. stage 3
-full thickness skin loss
pressure ulcer
-involves damage and necrosis
