Which nursing action should be implemented to address potential peripheral neurovascular dysfunction in a client who has sustained a fracture?

• A. Observe the client's pupillary response to light every 8 hours.
• B. Measure calf circumferences every 12 hours.
• C. Assign a PN to take the client's vital signs every 2 hours.
• D. Assess for sensation and movement of the feet every 4 hours.

Answer: (D)

The main idea is to continuously monitor the limb’s nerve function to catch any narrowing of blood flow or nerve compression early. After a fracture, swelling and shifting tissue can jeopardize perfusion and nerve integrity, so checking how the foot feels and moves directly assesses the most vulnerable aspects of peripheral neurovascular status. Assessing sensation reveals numbness or tingling that may indicate nerve irritation or compression, while evaluating movement shows whether motor nerves are being affected. Doing this every few hours provides timely information, so if changes are detected, you can prompt immediate action to prevent lasting damage.

Pupillary response is a cranial-nerve check and doesn’t inform about the injured leg’s neurovascular status. Measuring calf circumference focuses on swelling magnitude and potential venous complications rather than nerve function. Assigning a nurse to take vital signs is important for overall systemic status but won’t reliably detect evolving neurovascular compromise in the affected extremity. If sensory changes or reduced movement are observed, escalate care promptly and reassess the limb’s condition.
