Integumentary Part Three Flashcards
what are bioseynthetic grafts
combination of collagen and synthetics
what are autolytic dressings
use of moist dressings sch as hydrogels or hydrocolloids
xenograft AKA
heterograph
sanguineous exudate
contains blood
allograft
use of other human skin (cadaver skin)
purulent exudate
contains pus
a Bates-Jensen wound assessment tool would be used for
decubitis (pressure) ulcer
xenograph
use of skin from other species (pigskin)
what is full-thickness graft
contains epidermis and upper layers of dermis from donor site
what is an indolent ulcer
ulcer that is slow to heal
when is compression for venous/arterial ulcers contraindicated
when ABI is less than 0.7
DVT
dark pigmentation (not skin tone) AKA
hemosiderosis
what is sulfamylon
penetrates through eschar
diabetes is associated with
arterial disease
peripheral neuropathy
hemodierosis is common with
venous ulcers
gold standard for DVT assessment
venogram
what is split-thickness graft
contains epidermis and upper layers of dermis and donor site
The Wagner Classification System is used for
diabetic ulcers
clean red wounds indicate
healthy granulating wounds (in need of protection)
black wounds indicate
covered with eschar (dried necrotic tissue)
how are pulses with venous ulcers
normal
how is pain with venous ulcer
none to aching pain in dependent position
what classification system is used for diabetic ulcers
Wagner Classification
what is maceration
softening of skin associated with excessive moisture
pain with diabetic ulcer?
not really, nah
what type of scar stays within the boundaries of the burn
hypertrophic
keloid extends beyond boundaries
location of pressure ulcers (in general)
over bony prominences
purpose of hydrogels or hydrocolloids (autolytic dressings)
help remove eschar
how is skin surface temperature done
thermistor (temperature probe)
emergency care for burns
immersion in cold water
cold compress
sterile bandage (no ointments or creams)
what is silver sulfadiazine
common topical agent
appearance comparison for arterial and venous ulcers
arterial: irregular, smooth edges, DEEP
venous: dark pigmentation, fibrotic, SHALLOW
pain with indolent ulcer
NOPE
autograft
use of patient’s own skin
how to measure depth of a wound
insert sterile cotton tip applicator into deepest part of wound
examples of mechanical debridement
wet to dry dressings
pulsed lavage
gentle washing
where do diabetic ulcers appear
where arterial ulcers appear
peripheral neuropathy appear (plantar aspect of the foot)
what does dermal healing result in
scar formation
drainage comparison for arterial and venous ulcers
arterial: no drainage
venous: moderate to large amount of exudate
pain comparison for arterial and venous ulcers
arterial: painful (especially with elevation)
venous: little pain, comfy with elevation
common hand deformity following burn
claw hand
when is allograft used
temporary grafts for large burns
until autograft is available
serous exudate
watery serum
gangrene with venous ulcers?
nein
what is tunneling
underlying tissue destruction beneath intact skin
what is an unstageable pressure ulcer grade
tissue depth is obscured due to slough or eschar
extent of damage can’t be determined
yellow wounds indicate
include slough (necrotic or dead tissue)
what scales (3) are used to determine risk for pressure ulcers
Gosnell
Braden
Norton
staging for venous, arterial, and diabetic ulders are used for…
partial and full-thickness classifications
how are pulses with arterial ulcers
decreased/absent
most common places for venous ulcers
anywhere in the lower leg
medial malleolus common
