Which findings most strongly indicate impaired peripheral neurovascular function?

• A. Normal sensation and movement of the feet with strong pedal pulses.
• B. Diminished sensation and movement of the feet, diminished pedal pulses, pallor, and pain.
• C. Edema with warm skin.
• D. Normal color, but numbness only.

Answer: (B)

Peripheral neurovascular function reflects both nerve integrity and blood flow to the extremities. The most telling sign is a combination of neural impairment and vascular compromise. When sensation and movement are diminished, and this occurs alongside weak pedal pulses, pallor, and pain, it signals that nerves are not functioning properly and arterial blood flow is reduced. This concurrent nerve dysfunction and ischemia is the strongest indication of impaired peripheral neurovascular function.

Edema with warm skin suggests other processes, such as venous issues or inflammation, and normal color with numbness alone points to neuropathy without significant vascular involvement. The mixed pattern of sensory and motor loss with reduced pulses and pallor best reflects true neurovascular impairment.
