Answers
What is the normal capillary refill time?
Less than 2 seconds.
What ABI indicates normal arterial perfusion?
1.0-1.3.
What ABI indicates peripheral arterial disease (PAD)?
Less than 0.90.
An ABI less than 0.40 suggests what?
Severe peripheral arterial disease.
A patient reports calf pain that occurs with walking and improves with rest. What is the
most likely diagnosis?
Peripheral arterial disease (intermittent claudication).
Which condition causes leg pain that improves when the legs are in a dependent
position?
Peripheral arterial disease.
Which condition causes leg pain that improves with elevation?
Chronic venous insufficiency.
What skin finding is most consistent with peripheral arterial disease?
Thin, shiny skin with hair loss.
,What skin finding is most consistent with chronic venous insufficiency?
Brown discoloration around the ankles.
Where are arterial ulcers most commonly located?
Toes, lateral malleolus, pressure points.
Where are venous ulcers most commonly located?
Medial malleolus.
How do arterial ulcers typically appear?
Deep, punched-out lesions with pale wound beds.
How do venous ulcers typically appear?
Shallow, irregular ulcers with drainage.
Which pulses are often diminished in PAD?
Dorsalis pedis and posterior tibial pulses.
A patient has unilateral leg swelling, warmth, and calf tenderness. What should the NP
suspect?
Deep vein thrombosis.
What is the gold standard imaging test for suspected DVT?
Venous duplex ultrasound.
Why is Homan's sign no longer recommended?
It is neither sensitive nor specific for DVT.
What edema grade is considered mild pitting edema?
, 1+ (2 mm).
What edema grade is considered moderate pitting edema?
2+ (4 mm).
What edema grade rebounds in 10-20 seconds?
3+ edema.
What edema grade rebounds in more than 30 seconds?
4+ edema.
Bilateral lower extremity edema is commonly associated with what?
Heart failure.
Unilateral edema is more concerning for what?
DVT or localized obstruction.
What is lymphedema?
Protein-rich swelling caused by lymphatic obstruction.
How does lymphedema differ from venous edema?
Lymphedema is usually non-pitting in later stages.
Which pulse is palpated behind the medial malleolus?
Posterior tibial pulse.
Which pulse is palpated on the dorsum of the foot?
Dorsalis pedis pulse.
