CWCN LATEST 2026 EXAM QUESTIONS AND SOLUTIONS
RATED A+
✔✔Shear - ✔✔___________ causes elongated wounds with undermining and
tunneling.
✔✔True - ✔✔True or False: Iodine and silver will inactivate collagenase.
✔✔Nickel - ✔✔A ____________ thick layer of collagenase should be applied to a
wound.
✔✔collagenase - ✔✔The only enzyme available in the US as a debriding agent is
_____________. It is derived from clostridium bacteria and dissolves the collagen
anchors that secure the necrotic tissue to the wound bed. This process takes several
days to weeks.
✔✔enzymatic - ✔✔___________________ debridement (collagenase) is safe for
infected wounds. However, it does not have any local antimicrobial effects.
✔✔crystal violet, methylene blue, sodium hypochlorite - ✔✔Collagenase is safe for use
with which three antimicrobial products?
✔✔True - ✔✔True or False: The nurse uses a waterpik on high setting for wound
cleansing, but this causes bacteria to be driven further into the wound tissues.
✔✔nutrition - ✔✔At the end of the inflammatory phase, the patient's ______________
status should be monitored because a positive nitrogen balance is key for the
proliferative phase of wound healing.
✔✔catabolic - ✔✔Oxandrolone is for patients who are in a persistent ______________
state and have trouble breaking out of this state.
✔✔D - ✔✔If the patient is responding to nutritional support, but their wound is clean and
non granulating, which supplements should be considered?
A. L-Arginine
B. Glutamine
C. Vitamin A
D. A and B
✔✔silver nitrate (AgNO3) - ✔✔___________________ Can be used to reopen rolled
wound edges.
,✔✔48 hours - ✔✔A normally healing surgical incision is usually fully re-epithelialized
within ________________ of closure.
✔✔Vitamin A - ✔✔Steroids have a profound negative impact on wound healing. Topical
___________________ can be used to counteract the effects of steroids on an open
wound bed.
✔✔wet to dry - ✔✔a mechanical, nonselective form of debridement, appropriate for
heavily necrotic and infected wounds without visible granulation tissue.
✔✔False - ✔✔True or False: When using wet-to-dry gauze mechanical debridement,
one should moisten the gauze before pulling it from the wound bed.
✔✔Charcot's foot - ✔✔fracture, subluxation, and/ or dislocation of joints in the foot or
ankle related to diabetic neuropathy
✔✔Becaplermin (Regranex) - ✔✔Nonhealing diabetic (neuropathic) foot ulcers with
clean wound beds, no infection, and proper offloading may benefit from
___________________ gel therapy.
✔✔0.4 - ✔✔Critical ischemia of a limb is determined when the ABI is less than
✔✔30 - ✔✔TcPO2 (transcutaneous oxygen tension) is consistent with critical limb
ischemia when it is below ____ mm Hg.
✔✔computed tomographic angiography - ✔✔___________________________
provides accurate identification of the anatomic location and degree of stenosis in
arterial disease and should be done when the patient is being worked up for
revascularization for LEAD.
✔✔Cilostazol (Pletal) - ✔✔____________________ is an antiplatelet agent that is first-
line therapy for LEAD. However, avoid this drug for patients with heart failure.
✔✔autoimmune - ✔✔Vasculitic ulcers are commonly found in patients who also have
___________________ disorders.
✔✔vasculitis - ✔✔An autoimmune connective tissue disease that leads to inflammation
and potential damage to vital organs. Characterized by damage and destruction of
blood vessels. Often involves ulcers with severe pain that doesn't improve with rest,
positioning, or activity.
✔✔elevation - ✔✔In venous ulcers, the pain typically improves with limb
______________________.
, ✔✔True - ✔✔True or False: In patients with arterial ulcers, the pain is worse with
activity and relieved with rest.
✔✔denuded - ✔✔Barrier powder around fistulas is used to treat __________________
skin.
✔✔adhesive - ✔✔Liquid barrier products for fistulas are used to protect the skin from
_______________ trauma.
✔✔dressings - ✔✔Moisture barrier products are appropriate only for low-output fistulas
managed with ________________.
✔✔squamous cell carcinoma - ✔✔This type of skin cancer begins as a firm, red nodule
or scaly, crusted flat lesion. Can spread if not treated.
✔✔actinic keratosis - ✔✔The precursor of squamous cell carcinoma is called
___________________; appears as scaly pink papules on the head, face, dorsal
hands/forearms.
✔✔basal cell carcinoma - ✔✔The most common skin cancer that begins as a papule
and develops a central crater. Usually only spreads locally.
✔✔cryotherapy - ✔✔_______________ is commonly used to treat actinic keratosis.
✔✔Mohs - ✔✔Basal and Squamous cell carcinoma may be treated by _______
micrographic surgery because it allows preservation of normal tissue and complete
resection of the tumor. Has a cure rate of 95% for both diseases.
✔✔macrophages - ✔✔__________________ release growth factors in the inflammation
stage of healing that attract fibroblasts to the wound.
✔✔fibroblasts - ✔✔In the inflammation stage of healing, ________________ are
responsible for beginning angiogenesis and the formation of collagen (Type III), as well
as initiating epithelialization.
✔✔True - ✔✔True or False: Diabetic foot wounds with periwound callus should be
routinely debrided for callus removal, even if infected.
✔✔metronidazole - ✔✔best option to treat odor and infection in necrotic tumors.
✔✔curette - ✔✔a surgical instrument used to remove material by a scraping action,
especially from the uterus.
