CWCN STUDY GUIDE 2026 EXAM QUESTIONS AND
SOLUTIONS RATED A+
✔✔A ( The healing cascade is compromised by the impermeable
components of the hydrocolloid. Polyurethane foam is the most appropriate choice as
the primary function of foam is absorption) - ✔✔During a routine dressing change, the
nurse observes
the wound bed to be covered with fragile,
moist, red granulation tissue, which has grown above skin level. The current dressing
orders are
for hydrocolloid dressing, changed every 3 days.
Which of the following dressings is MOST appropriate
for the nurse to recommend at this time?
A. Polyurethane foam
B. Moist gauze
C. Transparent fi lm
D. Hydrogel sheet
✔✔1.0 - ✔✔Optimal arterial perfusion of the lower extremity
is best indicated by an ABI of ____.
✔✔Ischial tuberosity - ✔✔____________________________ ulcers
occur from prolonged erect seating in chair or wheelchair.
✔✔Trochanter - ✔✔_____________________ ulcers occur when individuals rest in
a lateral position, are allowed to lie in that position for
long periods of time, or have severe contractures and are
only able to be positioned laterally.
✔✔occiput - ✔✔The _____________ is the
most common location for pressure ulcer development in
infants and children.
✔✔bariatric - ✔✔The sacrum/coccyx, heels, and buttocks are the
most common locations for hospital-acquired pressure ulcers
in the _____________________ patient population.
✔✔10 days - ✔✔When Dakin's solution
is used, the current recommendation is a short-term
treatment—no more than _____________
✔✔surgical - ✔✔When large amounts
of tissue need to be removed in a life-threatening
situation, ____________ debridement is the best choice.
,✔✔b (Foot care is crucial, as limb preservation
is a primary concern of the WOC nurse.) - ✔✔A WOC nurse is providing teaching to a
diabetic
patient. Which is the most important aspect to
emphasize?
a. Insulin administration
b. Foot care
c. Blood sugar regulation
d. Skin care
✔✔b - ✔✔Interventions helpful in reducing pain for the patient
by using a negative-pressure wound therapy
wound unit include
a. the use of polyurethane instead of polyvinyl
foam
b. discontinuation of the unit 30 minutes prior to
removal
c. avoiding packing tunnels and undermining
d. the use of intermittent pressure throughout
treatment
✔✔polyvinyl - ✔✔_____________ foam with negative pressure wound therapy will
cause less pain for patients.
✔✔continuous - ✔✔To reduce pain in NPWT patients, the nurse should set the machine
to _________________ pressure.
✔✔a (All of the diagnoses mentioned in the
question may be treated with hyperbaric oxygen;
however, it is a primary therapy for air/gas embolism.) - ✔✔A trauma patient is admitted
to critical care with suspected
air embolism. Additionally, the patient has
profound blood loss, a diabetic foot ulcer, and an
acute myocardial infarction. Which condition is the
primary indication for hyperbaric oxygen therapy?
a. Air embolism
b. Blood loss
c. Diabetic foot ulcer
d. Myocardial infarct
✔✔Intertriginous dermatitis - ✔✔a skin injury that
is sometimes referred to as a kissing injury that presents as
mirror image skin damage, often in a linear pattern, on touching
tissues such as in the gluteal cleft or skin folds.
, ✔✔d (In this situation,
successful wound management is not dependent on the disease
process as it is controlled.) - ✔✔Th e WOC nurse is completing an initial assessment on
a patient with controlled type 2 diabetes mellitus (DM)
and a chronic diabetic neuropathic foot ulcer. Which of
the following factors has the lowest risk of impacting the
development of a sustainable wound care plan?
a. Cultural factors
b. Financial resources
c. Cognitive ability
d. Disease process
✔✔vasculitis - ✔✔Small vessel inflammation, as seen in ______________,
can damage vascular tissue. May initially present as palpable nodules or petechiae. The
lesions range from erythematous, nonblanching macules and/or nodules to hemorrhagic
vesicles and palpable purpura. As the damaged vessels become necrotic, hemorrhagic
bullae with
ulceration will develop. Pain is severe and does not improve with rest, positioning, or
activity. General signs are fever, myalgias, arthralgias, and malaise.
✔✔renal - ✔✔A history of ____________ disease combined with painful violaceous
hued lesions over their upper legs should raise suspicion for calciphylaxis.
✔✔False (early aggressive surgical debridement and skin grafting are appropriate, but
with instrumental debridement there is risk of poor healing) - ✔✔True or False:
Instrumental debridement is an appropriate management for calciphylaxis.
✔✔corticosteroids - ✔✔Local or systemic _________________________ are not
recommended for calciphylaxis because they may exacerbate the condition.
✔✔a - ✔✔When caring for a 30-year-old man with Stevens-Johnson
syndrome, what topical dressing should be considered?
a. Petrolatum contact layer dressing
b. An occlusive transparent dressing
c. Dry gauze with no contact layer
d. Hydrocolloid dressing
✔✔Acute irritant contact dermatitis -
✔✔______________________________________________ occurs
when an irritant, chemical or physical agent, disrupts
the topmost layer of the epidermis, thus leading to loss of
skin barrier. In this case, a change in soaps, creams, or shampoos
should be looked for when reviewing the patient's history.
