Which symptom is NOT consistent with diminished peripheral circulation?

Capillary refill less than 3 seconds is a sign of adequate peripheral circulation. Capillary refill time is a quick clinical test used to assess perfusion and circulation in the peripheral tissues. In a healthy individual, capillaries refill rapidly after pressure is applied, indicating good blood flow.

In contrast, the other symptoms listed are indeed consistent with diminished peripheral circulation. Diminished hair on the legs can occur due to poor blood flow to hair follicles, as healthy hair growth relies on adequate circulation. Skin that is cool to the touch suggests reduced blood flow to the area, often resulting from a lack of warmth provided by warm blood. Darkened skin on extremities can indicate chronic venous insufficiency or other circulatory issues where blood and its by-products accumulate, leading to changes in skin coloration.

Thus, diminished capillary refill time is not a symptom of poor circulation, while the other listed symptoms reflect common findings associated with reduced peripheral blood flow.
