COMPLETE SOLUTIONS VERIFIED
Aging and Skin: what occurs?
Skin becomes thinner, drier & wrinkled
Changes in pigmentation
Fewer melanocytes (less protection of UV radiation)
Thickness of dermis decreased
Loss of barrier protection due to decreased blood supply & lymphatic drainage
Pressure Ulcers: are? factors? decubitus ulcer is what?
Caused by unrelieved pressure that leads to damage of underlying tissue
Pressure, shearing forces, friction & moisture
Result of lying in recumbent position for extended periods
Pressure Ulcers: risk factors?
Older adult in hospital or nursing home
Neurologic disorders leading to loss of mobility or sensation
Immobilization
Intontinence
Debilitation
Lying in bed without changing position or relieving pressure
Laying for hours on hard imaging & operating tables
Pressure Ulcers: pathophysiology? what does non-blanching erythema
indicates?
, Continuous pressure between bony prominence & resistant outside surface distorts
capillaries and blocks blood & oxygen supply
If it is relieved within a few hours, non lasting tissue damage
1st sign of a pressure ulcer
Pressure Ulcers: treatment?
Necrotic tissue stimulates inflammatory response with hyperemia, fever & increased
WBC count
Large ulcers leads to anorexia, debility & renal insufficiency
Keep wound bed moist, flat & clean
Keloids: are what? caused by?
Elevated, rounded & firm scars with irregular margins beyond original site of injury
Abnormal wound healing with excessive fibroblast activity & collagen formation
Inflammation: dermatitis is? irritant contact is? stasis is caused by?
Inflammation of dermis
Contact reaction
Venous stasis & edema
Dermatitis: clinical manifestations?
Erythema
Swelling
Pruritis
Vesicular lesions in areas of allergen contact
Pattern of distribution indicates clues about allergen
Atopic Dermatitis: is what?
