Integumentary Part Four Flashcards
does epidermis contain blood vessels
NAWH
continous moist wounds purpose
protection of clean wounds
autolytic debridement of eschar
delivery of topical needs
what is Hyperbaric oxygen therapy
patient breathes 100% oxygen in a sealed, full body chamber with elevated atmospheric pressure
what is pulsed levage
delivery of irrigating solution under pressure that is produced by an electrically powered device
what side of the foams are hydrophobic and hydrophilic
hydrophobic: nonwound side
hydrophillic: wound side
Semmes-Weinstein monofilaments… what are the normal sized filament
5.07
contraindications for occlusive dressings
infection
deep ischemic ulcers
full thickness burns
stage IV ulcers
can vacuum-assisted closure be used with infection
yes
what are foams
cushion and protect the wound
these dressings are hydrophilic and hydrophobic
what is contained within the dermis
blood vessels
lymphatics
nerve endings
sebaceous/sweat glands
what are hydrogels
water or glycerine based gels
purpose of alginates
wounds with moderate to large amount of exudate
or
with combination exudate and necrosis
recommended pressure range for wound cleansing
4-15 psi
normal location of aterial insufficiency ulcers
lateral malleolus
toes
what is dermis made of
collagen and dense irregular CT
purpose of hydrocolloid dressing
absorbs minimal to moderate exudate
protects partial thickness wounds
trophic changes can indicate
poor arterial nutrition
pulsed levage with vacuum assists in…
removal of wound debris
itching AKA
pruritis
edema management: compression stockings AKA
Jobst
what is turgor
lift skin on back of hands
tells about hydration status
purpose of the cathode for estim with wound healing
to promote granulation
control inflammation
inhibit certain bacteria
is whirlpool therapy good for wound care
NO DONT DO IT
continuous dry gauze purpose
heavily exudating wounds
surgical interventions are used for what ulcers
III
IV
normal capillary refill time
less than 3 seconds
purpose of vacuum-assisted closure
when a wound is not closing
lack of arterial perfusion
excessive exudate that can’t be controlled with dressing
best ultrasound currents for edema management
high voltage pulsed
pulsed biphasic
what type of ultrasound should be used for wound healing
low intensity
pulsed
3x/week
ABCDs of melanoma examination
Asymmetry
Border: edges are irregular
Color: color varies throughout the mole
Diameter: mole’s diameter is over 6mm
purpose of films
to maintain moist wound environment with minimum to moderate exudate often in stage 1 and stage 2 pressure ulcers
contraindications for hyperbaric oxygen therapy
untreated pneumothorax
some antineoplastic medications
negative-pressure wound therapy AKA
vacuum-assisted closure
normal finding for rubor of dependency test
sole of foot should exhibit rubor in neutral in less than 15 seconds
what are hydrocolloid dressings
adhesive wafers that interact with the wound to form gelatinous mass
wound matrix dressings: what is it
provide a scaffolding for cellular deposit
what is negative-pressure wound therapy
open-cell foam dressing placed into wound
controlled subatmospheric pressure is applied via specialized device
what meds should be used for iontophoresis for wound healing
zince
histamine
purpose of hydrogels
used with partial or full thickness wounds with necrosis
minimal amounts of exudate
for cleaning most ulcers, what type of medication is used IN GENERAL
normal saline (0.9% NaCl)
purpose of the anode for estim with wound healing
used to promote epithelial cell migration
and
for reactivation of the inflammatory phase
what are films
clear adhesive membrane permable to atmospheric oxygen and moisture vapor and impermeable to water, bacteria, and contaminants
cyanosis can indicate ____ insufficiency
arterial
what is wet-to-dry gauze removal
mechanical debridement of necrotic tissue and slough
most common e-stim for wound healing
HVPC
what is contained within the subcutaneous tissue
loose CT and fat
purpose of negative-pressure wound therapy (vacuum-assisted closure)
helps maintain a moist wound environment
control edema
increase localized blood flow
reduce infectious material
when is gauze useful
early debridement
exudate present
wound with dead spaces/tunneling
necrotic tissue with exudate
purpose of occlusive dressings
useful to maintain tissue hydration
facilitate autolytic debridement
wound healing with less pain
