Which assessment finding most strongly suggests a neurovascular problem in an injured limb?

• A. 1+ pedal pulse
• B. 5/5 motor strength
• C. Numbness and tingling
• D. Pink and warm skin

Answer: (C)

Numbness and tingling reflect altered sensory nerve function in the injured limb, which is a direct sign of neurovascular involvement. When nerves are irritated, compressed, or damaged, abnormal sensations like pins and needles often appear early, signaling that the nerve pathways are not working properly and may be accompanied by vascular issues.

In contrast, a weak pedal pulse points to reduced blood flow but doesn’t specifically indicate nerve injury; full motor strength means the motor nerves still function well, and pink and warm skin suggests good perfusion. These findings are less indicative of a neurovascular problem than sensory disturbance, which is why numbness and tingling is the strongest clue.
