CWCN Exam ACTUAL QUESTIONS AND
CORRECT ANSWERS
The Pressure Ulcer Tool for Healing (PUSH) tools is based on what three characteristics of a
wound? - CORRECT ANSWERS surface area, type of tissue, volume of exudate
Severe neutropenia (<500) is a contraindication for __________________ debridement. -
CORRECT ANSWERS autolytic
An ___________ is the most accurate noninvasive approach to diagnosis of osteomyelitis. -
CORRECT ANSWERS MRI
Any level of __________________________ is an indicator of wound infection. - CORRECT
ANSWERS B-hemolytic strep
Hydrocolloids are to be avoided for skin tears because they are aggressively
___________________. - CORRECT ANSWERS adhesive
occlusive dressings made of material like pectin, gelatin, or carboxymethylcellulose. Self-
adhesive dressings that provide a moist healing environment and autolytic debridement but only
light-moderate absorption. Recommended for clean, shallow wounds with minimal exudate. Can
be used to protect intact skin or newly resurfaced breakdown. - CORRECT
ANSWERS hydrocolloids
Protective __________ can be used in patients with frail skin to prevent skin tears. - CORRECT
ANSWERS sleeves
,A condition that happens due to moisture trapping in skin folds, presenting as beefy-red
maculopapular rashes with peripheral scaling and distinct satellite lesions. - CORRECT
ANSWERS candidal intertrigo
candidal intertrigo is treated with topical or oral __________________. - CORRECT
ANSWERS antifungals (e.g. nystatin, fluconazole)
Life-threatening immune-mediated skin/mucous membrane disorder. Significant epidermal
necrosis and detachment. Often results from a drug reaction. Usually severe with more than 30%
Body Surface Area Skin detachment. - CORRECT ANSWERS Toxic Epidermal
Necrolysis (TEN)
The most commonly implicated medication for patients with SJS/TEN is
____________________. - CORRECT ANSWERS allopurinol
Fever, Flu-like symptoms, malaise, muscle aches, eye pain, pain with swallowing, skin
tenderness, inflammation, blistering.
Later disease involves confluent, red oval macules/papules with pruritic centers or diffuse
erythema. Widespread blistering and epidermal sloughing. Lesions usually start on the face and
spread. - CORRECT ANSWERS Toxic Epidermal Necrolysis
Care of the patient with TEN should resemble burn care with aggressive __________
management. - CORRECT ANSWERS fluid
_____________________ and other nonadherent contact layer dressings are commonly used for
patients with Toxic Epidermal Necrolysis. - CORRECT ANSWERS Petrolatum
,Aggressive _______________ is not indicated in Toxic Epidermal Necrolysis Syndrome because
of extensive denudation. - CORRECT ANSWERS debridement
Which gauze is a better choice for dressings that come into contact with the wound bed:
nonwoven or woven? - CORRECT ANSWERS Nonwoven
The lesions of this disease typically begin as erythematous, painful, edematous areas on the skin
after major or minor skin trauma. Often mistaken for cellulitis. Most commonly on the
extremities, sometimes on the perianal and trunk. Signs include fever and chills. Lab values
included elevated WBCs and anemia. - CORRECT ANSWERS Necrotizing fasciitis
True or False: Aggressive debridement is not recommended for Necrotizing Fasciitis patients. -
CORRECT ANSWERS False (needs aggressive debridement and broad-spectrum IV
antibiotics.)
______________ oxygen is a treatment option for necrotizing fasciitis patients. - CORRECT
ANSWERS Hyperbaric
__________________________ is considered the standard of care after a clean wound bed has
been established in the necrotizing fasciitis patient. - CORRECT ANSWERS negative
pressure wound therapy (NPWT)
___________ causes elongated wounds with undermining and tunneling. - CORRECT
ANSWERS Shear
True or False: Iodine and silver will inactivate collagenase. - CORRECT ANSWERS True
A ____________ thick layer of collagenase should be applied to a wound. - CORRECT
ANSWERS Nickel
, 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. - CORRECT
ANSWERS collagenase
___________________ debridement (collagenase) is safe for infected wounds. However, it does
not have any local antimicrobial effects. - CORRECT ANSWERS enzymatic
Collagenase is safe for use with which three antimicrobial products? - CORRECT
ANSWERS crystal violet, methylene blue, sodium hypochlorite
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. - CORRECT ANSWERS True
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. -
CORRECT ANSWERS nutrition
Oxandrolone is for patients who are in a persistent ______________ state and have trouble
breaking out of this state. - CORRECT ANSWERS catabolic
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
