The choice that indicates diminished pulses with cyanotic cool extremities is the hallmark of peripheral vascular disease (PVD) claudication. PVD, characterized by atherosclerosis or other vascular obstruction, impairs blood flow to the extremities, particularly during periods of increased demand such as walking.

When claudication occurs, patients often present with pain or cramping in the legs due to inadequate blood supply. This reduced perfusion results in diminished peripheral pulses, which can be assessed during the physical exam. Additionally, affected extremities become cyanotic (a bluish discoloration) and cool due to the lack of adequate blood flow. This finding is crucial in differentiating PVD from other causes of leg pain.

In contrast, increased capillary refill time typically reflects conditions of hypoperfusion or shock, while normal leg strength would suggest that the claudication is not due to vascular insufficiency. Swelling in the extremities may indicate venous insufficiency or other conditions unrelated to PVD. Therefore, diminished pulses with associated skin changes accurately represent the vascular compromise seen in PVD claudication.
