CWCN Exam Prep questions and
answers rated A+
surface area, type of tissue, volume of exudate - correct answer ✔✔ The Pressure Ulcer Tool for
Healing (PUSH) tools is based on what three characteristics of a wound?
autolytic - correct answer ✔✔ Severe neutropenia (<500) is a contraindication for
__________________ debridement.
MRI - correct answer ✔✔ An ___________ is the most accurate noninvasive approach to
diagnosis of osteomyelitis.
B-hemolytic strep - correct answer ✔✔ Any level of __________________________ is an
indicator of wound infection.
adhesive - correct answer ✔✔ Hydrocolloids are to be avoided for skin tears because they are
aggressively ___________________.
hydrocolloids - correct answer ✔✔ 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.
sleeves - correct answer ✔✔ Protective __________ can be used in patients with frail skin to
prevent skin tears.
,candidal intertrigo - correct answer ✔✔ A condition that happens due to moisture trapping in
skin folds, presenting as beefy-red maculopapular rashes with peripheral scaling and distinct
satellite lesions.
antifungals (e.g. nystatin, fluconazole) - correct answer ✔✔ candidal intertrigo is treated with
topical or oral __________________.
Toxic Epidermal Necrolysis (TEN) - correct answer ✔✔ 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.
allopurinol - correct answer ✔✔ The most commonly implicated medication for patients with
SJS/TEN is ____________________.
Toxic Epidermal Necrolysis - correct answer ✔✔ 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.
fluid - correct answer ✔✔ Care of the patient with TEN should resemble burn care with
aggressive __________ management.
Petrolatum - correct answer ✔✔ _____________________ and other nonadherent contact
layer dressings are commonly used for patients with Toxic Epidermal Necrolysis.
debridement - correct answer ✔✔ Aggressive _______________ is not indicated in Toxic
Epidermal Necrolysis Syndrome because of extensive denudation.
,Nonwoven - correct answer ✔✔ Which gauze is a better choice for dressings that come into
contact with the wound bed: nonwoven or woven?
Necrotizing fasciitis - correct answer ✔✔ 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.
False (needs aggressive debridement and broad-spectrum IV antibiotics.) - correct answer ✔✔
True or False: Aggressive debridement is not recommended for Necrotizing Fasciitis patients.
Hyperbaric - correct answer ✔✔ ______________ oxygen is a treatment option for necrotizing
fasciitis patients.
negative pressure wound therapy (NPWT) - correct answer ✔✔ __________________________
is considered the standard of care after a clean wound bed has been established in the
necrotizing fasciitis patient.
Shear - correct answer ✔✔ ___________ causes elongated wounds with undermining and
tunneling.
True - correct answer ✔✔ True or False: Iodine and silver will inactivate collagenase.
Nickel - correct answer ✔✔ A ____________ thick layer of collagenase should be applied to a
wound.
collagenase - correct answer ✔✔ 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 - correct answer ✔✔ ___________________ debridement (collagenase) is safe for
infected wounds. However, it does not have any local antimicrobial effects.
crystal violet, methylene blue, sodium hypochlorite - correct answer ✔✔ Collagenase is safe for
use with which three antimicrobial products?
True - correct answer ✔✔ 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 - correct answer ✔✔ 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 - correct answer ✔✔ Oxandrolone is for patients who are in a persistent
______________ state and have trouble breaking out of this state.
D - correct answer ✔✔ 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) - correct answer ✔✔ ___________________ Can be used to reopen
rolled wound edges.
48 hours - correct answer ✔✔ A normally healing surgical incision is usually fully re-
epithelialized within ________________ of closure.
