What finding would most likely require further evaluation for arterial obstruction?

The finding that would most likely require further evaluation for arterial obstruction is absent or diminished pulses. Pulses throughout the body, especially in the limbs, are crucial indicators of blood flow. When pulses are absent or significantly diminished, it suggests that there may be an obstruction in the arteries that is preventing proper blood circulation to that area. This could be due to a variety of reasons, such as atherosclerosis, embolism, or vessel spasm, which can lead to serious complications if not addressed.

In contrast, normal pedal pulses, symmetrical limb temperatures, and normal capillary refill are indicators of adequate circulation. Normal pedal pulses indicate that there is sufficient blood flow to the feet, while symmetrical limb temperatures suggest that blood is reaching both limbs equally. Similarly, a normal capillary refill time indicates that peripheral circulation is intact and functioning properly. These findings would not typically warrant further evaluation for arterial obstruction, unlike absent or diminished pulses which clearly signal potential vascular issues.
