hemolytic strep
Hydrocolloids are to be avoided for skin tears because they are aggressively ___________________. -
ANSWER ☑☑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. - ANSWER ☑☑hydrocolloids
Protective __________ can be used in patients with frail skin to prevent skin tears. - ANSWER
☑☑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. - ANSWER ☑☑candidal intertrigo
,candidal intertrigo is treated with topical or oral __________________. - ANSWER ☑☑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. - ANSWER ☑☑Toxic Epidermal Necrolysis (TEN)
The most commonly implicated medication for patients with SJS/TEN is ____________________. -
ANSWER ☑☑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. - ANSWER
☑☑Toxic Epidermal Necrolysis
Care of the patient with TEN should resemble burn care with aggressive __________ management. -
ANSWER ☑☑fluid
_____________________ and other nonadherent contact layer dressings are commonly used for
patients with Toxic Epidermal Necrolysis. - ANSWER ☑☑Petrolatum
Aggressive _______________ is not indicated in Toxic Epidermal Necrolysis Syndrome because of
extensive denudation. - ANSWER ☑☑debridement
Which gauze is a better choice for dressings that come into contact with the wound bed: nonwoven or
woven? - ANSWER ☑☑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. - ANSWER ☑☑Necrotizing fasciitis
,True or False: Aggressive debridement is not recommended for Necrotizing Fasciitis patients. - ANSWER
☑☑False (needs aggressive debridement and broad-spectrum IV antibiotics.)
______________ oxygen is a treatment option for necrotizing fasciitis patients. - ANSWER
☑☑Hyperbaric
__________________________ is considered the standard of care after a clean wound bed has been
established in the necrotizing fasciitis patient. - ANSWER ☑☑negative pressure wound therapy (NPWT)
___________ causes elongated wounds with undermining and tunneling. - ANSWER ☑☑Shear
True or False: Iodine and silver will inactivate collagenase. - ANSWER ☑☑True
A ____________ thick layer of collagenase should be applied to a wound. - ANSWER ☑☑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. - ANSWER ☑☑collagenase
___________________ debridement (collagenase) is safe for infected wounds. However, it does not
have any local antimicrobial effects. - ANSWER ☑☑enzymatic
Collagenase is safe for use with which three antimicrobial products? - ANSWER ☑☑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. - ANSWER ☑☑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. - ANSWER
☑☑nutrition
, Oxandrolone is for patients who are in a persistent ______________ state and have trouble breaking
out of this state. - ANSWER ☑☑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 - ANSWER ☑☑D
___________________ Can be used to reopen rolled wound edges. - ANSWER ☑☑silver nitrate
(AgNO3)
A normally healing surgical incision is usually fully re-epithelialized within ________________ of closure.
- ANSWER ☑☑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. - ANSWER ☑☑Vitamin A
a mechanical, nonselective form of debridement, appropriate for heavily necrotic and infected wounds
without visible granulation tissue. - ANSWER ☑☑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. - ANSWER ☑☑False
fracture, subluxation, and/ or dislocation of joints in the foot or ankle related to diabetic neuropathy -
ANSWER ☑☑Charcot's foot
