WEB WOC WOUND CARE EXAM (ACTUAL / ) STUDY

GUIDE QUESTIONS AND VERIFIED 100% CORRECT ANSWERS

arterial ulcer characteristics - --Answers---tips of the toes, pressure points usually small, may have tunneling, punched out appearance dry, pale tissue, may have necrosis well defined, smooth edges minimal exudate

etiology and diagnosis of LEAD - --Answers---Reduced arterial flow to the LE due to atherosclerosis

ABI/TBI to determine evidence of LEAD and severity, further testing needed if disease significant or no wound progress

neuropathic ulcer characteristics - --Answers---plantar aspects of feet, over pressure points round or oblong, punched out appearance necrotic, pink, pale well defined, smooth edges small-mod exudate

wagner's classifications- DFU - --Answers---grade 0: pre-

injury, skin intact, callus grade 1: superficial injury, partial or full thickness 1 / 4

grade 2: probing to ligament, tendon, joint capsule, soft tissue

infection

grade 3 : deep injury with abscess, osteomyelitis, or joint

sepsis

grade 4: gangrene to toes or fore foot

grade 5: gangrene to entire foot *needs amputation*

etiology and diagnosis of LEND - --Answers---damage to nerves causes neuropathy that leads to undetected repetitive pressure/trauma, inflammation with resulting ulceration

ABI/TBI to determine evidence of LEAD and severity, TBI better test due to vessel calcification. X-ray common with initial evaluation, MRI if probe to bone

vasculitic ulcers - --Answers---autoimmune connective tissue disease that targets blood vessels

acute pain, palpable purpura

sickle cell ulcers - --Answers---Inherited hematologic disorder of 100,000 persons in the U.S., mostly African American, diagnosis based upon history and presentation

painful nodule or pustule that breaks into large ulcer with violaceous border and red halo

calcyphylaxis - --Answers---Occurs most commonly in patients with chronic kidney disease on hemodialysis

star shaped, deep, purple ulcers that usually become gangrenous

superficial burn - --Answers---Epidermis only Typically develops from sunburn or scalding

Pain, warmth, redness, swelling, peeling epidermis

superficial, partial thickness burn - --Answers---Epidermis and dermis involved

Blistering, weeping moist skin. Dermal structures are intact.Painful

deep, partial thickness burn - --Answers---Deeper portions of the dermis damaged

• / 4

Red with waxy white tissue present, blister formation. Dry red wound bed. Disruption of hair follicles, nails, and glands

full thickness burn - --Answers---Entire dermis involved and extending into subcutaneous tissue; nerves destroyed

Waxy white to gray in color; may have charred (black leathery) appearance. No sensation of pain because tissue is avascular.

toxic epidermal necrolysis - --Answers---Maculopapular rash followed by erythema, painful skin and sloughing of large sheets of epidermis

Rare condition usually associated with a drug reaction.(sulfa, anticonvulsants etc) Involves over 30% of body; +Nikolsky sign

graft versus host disease - --Answers---Maculopapular rash that develops into bullae, generalized erythema and desquamation; painful and pruritic. Starts on palms, soles then spreads to face, chest, arms, shoulders.

A complication of transplantation or blood transfusion.
