Wound Care Certification Exam Wound Care Certification Lower Extremity Wound Management 1 — Questions and Answers
Question 1: Which characteristic is most typical of an arterial (ischemic) ulcer of the lower extremity?
- Irregular edges with ruddy granulation and heavy exudate
- Pale, well-defined 'punched-out' margins with minimal exudate (Correct answer)
- Wet, macerated periwound skin with hemosiderin staining
- Shallow, irregular borders located at the medial malleolus
Correct answer: Pale, well-defined 'punched-out' margins with minimal exudate
Arterial ulcers have pale, well-defined 'punched-out' margins with minimal exudate because reduced blood flow limits tissue perfusion and wound moisture.
Question 2: An ankle-brachial index (ABI) of 0.55 in a patient with a lower extremity wound most accurately indicates:
- Normal arterial perfusion adequate for healing
- Mild arterial disease requiring monitoring only
- Moderate to severe peripheral arterial disease (Correct answer)
- Venous insufficiency with secondary arterial involvement
Correct answer: Moderate to severe peripheral arterial disease
An ABI of 0.4–0.6 indicates moderate to severe peripheral arterial disease; values below 0.5 suggest critical limb ischemia requiring urgent vascular evaluation.
Question 3: Which anatomical location is most typical for venous stasis ulcers?
- Tips of the toes and dorsum of the foot
- Plantar surface of the foot at bony prominences
- Medial malleolus and gaiter area of the lower leg (Correct answer)
- Lateral malleolus and outer ankle
Correct answer: Medial malleolus and gaiter area of the lower leg
Venous ulcers most commonly occur in the gaiter area around the medial malleolus due to the highest concentration of venous hypertension in that region.
Question 4: Which physical finding is most consistent with chronic venous insufficiency of the lower extremity?
- Absent pedal pulses and dependent rubor
- Lipodermatosclerosis and hemosiderin staining (Correct answer)
- Dry, shiny, hairless skin with nail changes
- Pallor on elevation and rubor on dependency
Correct answer: Lipodermatosclerosis and hemosiderin staining
Lipodermatosclerosis (subcutaneous fibrosis) and hemosiderin staining (brown discoloration) are hallmarks of chronic venous insufficiency from red blood cell extravasation.
Question 5: A patient with a venous leg ulcer has an ABI of 0.82. What is the most appropriate first-line treatment?
- Urgent vascular surgery referral for arterial bypass
- Compression therapy with 30–40 mmHg sustained compression (Correct answer)
- Avoid all compression due to mixed arterial-venous disease
- Hyperbaric oxygen therapy to improve tissue perfusion
Correct answer: Compression therapy with 30–40 mmHg sustained compression
An ABI of 0.82 indicates adequate arterial perfusion, making full-strength compression therapy (30–40 mmHg) the appropriate evidence-based first-line treatment for venous ulcers.
Question 6: Which diagnostic study is considered the gold standard for evaluating peripheral arterial disease anatomy prior to intervention?
- Ankle-brachial index measurement
- Toe-brachial index measurement
- Duplex ultrasonography of lower extremities
- Arteriography (catheter-based angiography) (Correct answer)
Correct answer: Arteriography (catheter-based angiography)
Catheter-based arteriography remains the gold standard for anatomical mapping of peripheral arterial disease due to its superior spatial resolution and simultaneous intervention capability.
Question 7: Dependent rubor of the lower extremity, where the skin turns deep red when the limb is lowered, is a sign of:
- Chronic venous hypertension
- Severe arterial insufficiency (Correct answer)
- Lymphedema with secondary skin changes
- Diabetic autonomic neuropathy
Correct answer: Severe arterial insufficiency
Dependent rubor indicates severe arterial insufficiency; maximal vasodilation occurs at rest to maintain perfusion, and redness appears when gravity assists blood flow to the ischemic limb.
