Which tests are commonly used to assess arterial insufficiency in a limb with a wound?

• A. Assess skin temperature, color, and hair growth; palpate dorsalis pedis and posterior tibial pulses; capillary refill; perform Ankle-Brachial Index (ABI) or toe-brachial index; duplex ultrasound if indicated.
• B. Assess capillary refill only.
• C. Rely on patient-reported sensations alone.
• D. Rely on wound culture results.

Answer: (C)

Assessing arterial insufficiency in a limb with a wound relies on a thorough vascular exam with objective measurements, not just symptoms. This includes checking skin temperature and color, looking for hair growth changes, palpating distal pulses (like dorsalis pedis and posterior tibial), and evaluating capillary refill to gauge blood flow. Noninvasive tests such as the ankle-brachial index or toe-brachial index quantify perfusion and help classify severity, while duplex ultrasound can visualize blood flow and vessel patency when more detail is needed. Relying on patient-reported sensations alone misses perfusion problems, and wound culture results pertain to infection, not blood supply.
