ch 11 venous insuff ulcers Flashcards
o Venous insufficiency ulcers are the most common type of leg ulcer, accounting for _____% of all ulcers
70-90%
Sustained venous _________ is required for the development of venous insufficiency ulcerations
hypertension
According to this theory, ulceration results from local hypoxia due to venous congestion, white blood cell trapping, and the increased demands placed on affected tissues by the ensuing inflammatory response
white blood cell trapping theory
the cause of skin and tissue breakdown is ________ secondary to venous hypertension
hypoxia
gold standard for identifying DVT
venogram
special test/sign that can help identify the presence of a DVT
Homan’s sign
a Well’s DVT prediction score of _________ is considered high probability of DVT and further assessment should be requested
3 or higher
performing an ABI could dislodge a DVT.
T or F
True
Patients with venous insufficiency ulcers and an ABI less than 0.7 should be managed with compression due to coexisting arterial insufficiency.
T or F
False, SHOULD NOT
gold standard for evaluating the venous system
doppler US
pain pattern of venous insuff ulcers
mild to mod, decreased with elevation or compression
position of venous insuff ulcers
medial malleolus, medial lower leg
presentation of venous insuff ulcers
irregular shape
red or ruddy wound bed
copious drainage
periwound of venous insuff ulcers
edema
dermatitis
lipodermatosclerosis
pulses near venous insuff ulcers
normal or decreased
temperature of venous insuff ulcers
normal to mild
these factors do NOT affect venous ulcer healing
gender
race
skin condition
infection
standard of care for venous insuff ulcers provided arterial insuff is not present
compression
Bandages that are highly elastic are not appropriate for managing venous insuff ulcers
t or f
True
Highly elastic bandages, such as the typical Ace-type bandage, do NOT enhance the effectiveness of the calf muscle pump and have NOT been found to be effective in the management of venous insufficiency ulcers.
T or F
true
Contraindications to Compression Therapy for Patients with Venous Insufficiency
Arterial insufficiency with an ABI < 0.7 Acute infection Pulmonary edema Uncontrolled or severe congestive heart failure Active DVT
type of bandaging that is proven to be effect in managing compression for venous insuff ulcers
paste bandages
Venous insuff ulcers are the most common type of leg ulcer.
T or F
True
