Certified Wound Care Nurse (CWCN
Certification Exam) by
WOCNCB |comprehensive questions
and answers 2026
What are the interpretations of ABI? - correct-answer - ABI of 1.0 is pure LEVD
ABI of 0.9 or less is LEAD
ABI of 0.5 or less is ischemia
When should you obtain an TBI? - correct-answer - when ABI is >1.3 indicating
calcification of vessels which in turn reflects invalid data. A TBI of < 0.7 indicates
LEAD
What is the gold standard for evaluating valve failure and extent of reflux? -
correct-answer - duplex ultra sound
,2|Page
What are some methods for manaing venous ulcers and CVI - correct-answer -
limb elevation- >heart level for 1-2 hours/daily and during sleep, calf pump
exercises or referral to PT for shuffling gait, weight control, medications (diuretics,
topical corticosteroids, Pentoxifylline (Trental), and compression therapy
How does Pentoxifylline work and when is it appropriate? - correct-answer -
reduces aggregation of platelets and WBC, reducing capillary plugging and
enhances blood flow. ordered when standard therapy is not effective
When are elastic or inelastic compressions indicated? - correct-answer - elastic
for patients who are sedenatary vs. inelastic for patients who are amublatory
When are high pressure compressions (30-40mmgHg) indicated, when assessing
ABI? - correct-answer - ABI>0.8 can use high compressions
,3|Page
when are compressions contraindicated? - correct-answer - venous thrombosis in
LE w/ulcers and uncompensated heart failure
when is sustained (continuous) compression contraindicated? - correct-answer -
in the presene of PVD with an ABI that is < or =0.6 or when ABI is >0.5 but <0.8 is
more appropriate
when is IPC (intermittent pneumatic compression)-dynamic compression
indicated? - correct-answer - for patients with venous insufficiency and ABI< or
=0.5, for those who cannot tolerate sustained compression, as an adjunct therapy
to sustained therapy, those who are immobile
when is modified or lower compressions appropriate (23-30mmHg)? - correct-
answer - when coexisting arterial disease is present
, 4|Page
all patients with leg uclers should be screened for arterial disease using what,
initially? - correct-answer - doppler which measures ABI; takes BP in the arm and
ankle and compares ratio
What are the attributes of short-stretch compression? - correct-answer - it's
inelastic, sustained compression and provides a modified to therapeutic level of
pressure-reusable
What are the attributes of long-stretch compression? - correct-answer - same as
short stretch except it's elastic (ex. Surepress)
what are the attributes of multi-layer compression? - correct-answer - sustained,
elastic, disposable, and provides therapeutic to modified pressure (ex. 3M
w/coban)
