CWCN EXAM PREP QUESTIONS & ANSWERS
surface area, type of tissue, volume of exudate - Answer -The Pressure Ulcer Tool for
Healing (PUSH) tools is based on what three characteristics of a wound?
autolytic - Answer -Severe neutropenia (<500) is a contraindication for
__________________ debridement.
MRI - Answer -An ___________ is the most accurate noninvasive approach to
diagnosis of osteomyelitis.
B-hemolytic strep - Answer -Any level of __________________________ is an
indicator of wound infection.
adhesive - Answer -Hydrocolloids are to be avoided for skin tears because they are
aggressively ___________________.
hydrocolloids - 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 - Answer -Protective __________ can be used in patients with frail skin to
prevent skin tears.
candidal intertrigo - 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) - Answer -candidal intertrigo is treated with
topical or oral __________________.
Toxic Epidermal Necrolysis (TEN) - 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 - Answer -The most commonly implicated medication for patients with
SJS/TEN is ____________________.
Toxic Epidermal Necrolysis - 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 - Answer -Care of the patient with TEN should resemble burn care with aggressive
__________ management.
False (needs aggressive debridement and broad-spectrum IV antibiotics.) - Answer -
True or False: Aggressive debridement is not recommended for Necrotizing Fasciitis
patients.
Hyperbaric - Answer -______________ oxygen is a treatment option for necrotizing
fasciitis patients.
negative pressure wound therapy (NPWT) - Answer -__________________________
is considered the standard of care after a clean wound bed has been established in the
necrotizing fasciitis patient.
Shear - Answer -___________ causes elongated wounds with undermining and
tunneling.
True - Answer -True or False: Iodine and silver will inactivate collagenase.
Nickel - Answer -A ____________ thick layer of collagenase should be applied to a
wound.
collagenase - 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 - Answer -___________________ debridement (collagenase) is safe for
infected wounds. However, it does not have any local antimicrobial effects.
crystal violet, methylene blue, sodium hypochlorite - Answer -Collagenase is safe for
use with which three antimicrobial products?
True - 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.
Petrolatum - Answer -_____________________ and other nonadherent contact layer
dressings are commonly used for patients with Toxic Epidermal Necrolysis.
debridement - Answer -Aggressive _______________ is not indicated in Toxic
Epidermal Necrolysis Syndrome because of extensive denudation.
, Nonwoven - Answer -Which gauze is a better choice for dressings that come into
contact with the wound bed: nonwoven or woven?
Necrotizing fasciitis - 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.
nutrition - 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 - Answer -Oxandrolone is for patients who are in a persistent
______________ state and have trouble breaking out of this state.
D - 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) - Answer -___________________ Can be used to reopen rolled
wound edges.
48 hours - Answer -A normally healing surgical incision is usually fully re-epithelialized
within ________________ of closure.
Vitamin A - Answer -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 - Answer -a mechanical, nonselective form of debridement, appropriate for
heavily necrotic and infected wounds without visible granulation tissue.
False - Answer -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 - Answer -fracture, subluxation, and/ or dislocation of joints in the foot or
ankle related to diabetic neuropathy
Becaplermin (Regranex) - Answer -Nonhealing diabetic (neuropathic) foot ulcers with
clean wound beds, no infection, and proper offloading may benefit from
___________________ gel therapy.
