QUESTIONS AND ANSWERS 100% PASS
The Pressure Ulcer Tool for Healing (PUSH) tools is based on what three characteristics of a
wound? - ANS surface area, type of tissue, volume of exudate
Severe neutropenia (<500) is a contraindication for __________________ debridement. -
ANS autolytic
An ___________ is the most accurate noninvasive approach to diagnosis of osteomyelitis. -
ANS MRI
Any level of __________________________ is an indicator of wound infection. - ANS B-
hemolytic strep
Hydrocolloids are to be avoided for skin tears because they are aggressively
___________________. - ANS 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. -
ANS hydrocolloids

,Protective __________ can be used in patients with frail skin to prevent skin tears. -
ANS 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. - ANS candidal
intertrigo
candidal intertrigo is treated with topical or oral __________________. - ANS 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. - ANS Toxic Epidermal Necrolysis (TEN)
The most commonly implicated medication for patients with SJS/TEN is
____________________. - ANS 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. - ANS Toxic Epidermal Necrolysis
Care of the patient with TEN should resemble burn care with aggressive __________
management. - ANS fluid
_____________________ and other nonadherent contact layer dressings are commonly used
for patients with Toxic Epidermal Necrolysis. - ANS Petrolatum

,Aggressive _______________ is not indicated in Toxic Epidermal Necrolysis Syndrome because
of extensive denudation. - ANS debridement
Which gauze is a better choice for dressings that come into contact with the wound bed:
nonwoven or woven? - ANS 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. - ANS Necrotizing fasciitis
True or False: Aggressive debridement is not recommended for Necrotizing Fasciitis patients. -
ANS False (needs aggressive debridement and broad-spectrum IV antibiotics.)
______________ oxygen is a treatment option for necrotizing fasciitis patients. -
ANS Hyperbaric
__________________________ is considered the standard of care after a clean wound bed has
been established in the necrotizing fasciitis patient. - ANS negative pressure wound therapy
(NPWT)
___________ causes elongated wounds with undermining and tunneling. - ANS Shear
True or False: Iodine and silver will inactivate collagenase. - ANS True
A ____________ thick layer of collagenase should be applied to a wound. - ANS 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. - ANS collagenase

, ___________________ debridement (collagenase) is safe for infected wounds. However, it
does not have any local antimicrobial effects. - ANS enzymatic
Collagenase is safe for use with which three antimicrobial products? - ANS 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. - ANS 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. - ANS nutrition
Oxandrolone is for patients who are in a persistent ______________ state and have trouble
breaking out of this state. - ANS 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
D. A and B - ANS D
___________________ Can be used to reopen rolled wound edges. - ANS silver nitrate
(AgNO3)
A normally healing surgical incision is usually fully re-epithelialized within ________________ of
closure. - ANS 48 hours
