CWCA PRACTICE EXAM
PART 1
Question 1: Which combination most strongly supports venous insuciency as the primary cause of a lower-leg ulcer?
Choices:
1) Dry gangrene of a toe with absent pulses 2) Plantar callused ulcer with loss of sensation 3) Gaiter-area ulcer with edema, hemosiderin staining, and venous skin changes 4) Localized sacral injury after immobility Correct Answer: Gaiter-area ulcer with edema, hemosiderin staining, and venous skin changes
Explanation: Venous hypertension commonly produces lower-leg edema, hemosiderin
deposition, stasis skin changes, and ulcers in the gaiter region.Page 1
Question 2: How is the Braden Scale generally interpreted?
Choices:
1) A lower total score indicates greater pressure-injury risk 2) A higher total score always indicates greater risk 3) Only the moisture subscale determines risk 4) The scale is used to stage existing pressure injuries
Correct Answer: A lower total score indicates greater pressure-injury risk
Explanation: The Braden Scale estimates pressure-injury risk across several factors. Lower scores indicate increasing risk; it does not stage existing injuries.
Question 3: A patient with advanced kidney disease has marked lower-extremity
edema. How can edema impede wound healing?
Choices:
1) It permanently increases arterial inow 2) It increases interstitial diusion distance and can compromise local oxygen exchange 3) It causes keratinocytes to stop dividing in all tissues 4) It converts venous blood into lymph Correct Answer: It increases interstitial diusion distance and can compromise local oxygen exchange Explanation: Excess interstitial uid increases tissue pressure and diusion distance, which can impair oxygen and nutrient exchange and contribute to tissue fragility.Page 2
Question 4: Intact sacral skin has persistent nonblanchable erythema after pressure relief. How should this pressure injury be classied?
Choices:
1) Stage 2 2) Stage 3 3) Unstageable 4) Stage 1
Correct Answer: Stage 1
Explanation: Stage 1 pressure injury is intact skin with localized nonblanchable erythema. Skin color changes may present dierently in darker skin tones.Question 5: Which feature most strongly suggests a neuropathic diabetic foot ulcer?
Choices:
1) Painless plantar ulcer beneath a callused high-pressure area with loss of protective sensation 2) Painful punched-out ulcer on a cool toe with absent pulses 3) Shallow irregular ulcer near the medial ankle with edema and hemosiderin staining 4) Diuse moisture injury across the perineum after incontinence Correct Answer: Painless plantar ulcer beneath a callused high-pressure area with loss of protective sensation Explanation: Neuropathic ulcers commonly occur at plantar pressure points, often with callus and reduced protective sensation. Vascular status still must be assessed because mixed disease can occur.Page 3
