Which finding suggests diminished arterial perfusion in the extremities?

• A. Absent or diminished pulses
• B. Chest pain
• C. Jaundice
• D. Headache

Answer: (A)

Absent or diminished peripheral pulses reflect reduced arterial inflow to the limbs, which directly indicates diminished arterial perfusion. When arteries supplying the extremities are narrowed or blocked, the flow to hands or feet decreases, making pulses weaker or absent and signaling compromised limb blood supply. In practice, this is a primary sign clinicians look for when assessing peripheral perfusion, alongside other indications like pallor, cool temperature, and pain with movement. The other findings don’t point to limb perfusion. Chest pain suggests possible myocardial ischemia, jaundice points to liver or biliary issues, and headache has a broad range of causes not specifically tied to limb arterial flow.
