___________________. Right Ans - adhesive
occlusive dressings made of material like pectin, gelatin, or

beefy-red maculopapular rashes with peripheral scaling and distinct satellite
lesions. Right Ans - candidal intertrigo
candidal intertrigo is treated with topical or oral __________________. Right 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. Right Ans - Toxic Epidermal Necrolysis (TEN)
,The most commonly implicated medication for patients with SJS/TEN is
____________________. Right 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. Right Ans - Toxic Epidermal
Necrolysis
Care of the patient with TEN should resemble burn care with aggressive
__________ management. Right Ans - fluid
_____________________ and other nonadherent contact layer dressings are
commonly used for patients with Toxic Epidermal Necrolysis. Right Ans -
Petrolatum
Aggressive _______________ is not indicated in Toxic Epidermal Necrolysis
Syndrome because of extensive denudation. Right Ans - debridement
Which gauze is a better choice for dressings that come into contact with the
wound bed: nonwoven or woven? Right 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. Right Ans - Necrotizing fasciitis
True or False: Aggressive debridement is not recommended for Necrotizing
Fasciitis patients. Right Ans - False (needs aggressive debridement and
broad-spectrum IV antibiotics.)
______________ oxygen is a treatment option for necrotizing fasciitis patients.
Right Ans - Hyperbaric
,__________________________ is considered the standard of care after a clean wound
bed has been established in the necrotizing fasciitis patient. Right Ans -
negative pressure wound therapy (NPWT)
___________ causes elongated wounds with undermining and tunneling. Right
Ans - Shear
True or False: Iodine and silver will inactivate collagenase. Right Ans - True
A ____________ thick layer of collagenase should be applied to a wound. Right
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. Right Ans - collagenase
___________________ debridement (collagenase) is safe for infected wounds.
However, it does not have any local antimicrobial effects. Right Ans -
enzymatic
Collagenase is safe for use with which three antimicrobial products? Right
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. Right
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. Right Ans - nutrition
Oxandrolone is for patients who are in a persistent ______________ state and have
trouble breaking out of this state. Right 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 Right Ans - D
___________________ Can be used to reopen rolled wound edges. Right Ans -
silver nitrate (AgNO3)
A normally healing surgical incision is usually fully re-epithelialized within
________________ of closure. Right Ans - 48 hours
Steroids have a profound negative impact on wound healing. Topical
___________________ can be used to counteract the effects of steroids on an open
wound bed. Right Ans - Vitamin A
a mechanical, nonselective form of debridement, appropriate for heavily
necrotic and infected wounds without visible granulation tissue. Right Ans
- wet to dry
True or False: When using wet-to-dry gauze mechanical debridement, one
should moisten the gauze before pulling it from the wound bed. Right Ans -
False
fracture, subluxation, and/ or dislocation of joints in the foot or ankle related
to diabetic neuropathy Right Ans - Charcot's foot
Nonhealing diabetic (neuropathic) foot ulcers with clean wound beds, no
infection, and proper offloading may benefit from ___________________ gel
therapy. This gel is a platelet-derived growth factor. Right Ans -
Becaplermin (Regranex)
Critical ischemia of a limb is determined when the ABI is less than Right
Ans - 0.4
TcPO2 (transcutaneous oxygen tension) is consistent with critical limb
ischemia when it is below ____ mm Hg. Right Ans - 30
