Four hours after open reduction and internal fixation of a fractured tibia, a client reports increasing pain that is not relieved by prescribed opioid medication. The toes are pale and cool. Which action should the nurse take first?

Increasing pain unrelieved by opioids with pale, cool toes suggests possible neurovascular compromise or compartment syndrome. The nurse should immediately assess circulation, movement, and sensation and notify the provider. Delaying care or applying heat can worsen tissue injury.

Key concepts

• Neurovascular Assessment — Assessment of circulation, movement, and sensation in an extremity.
• Compartment Syndrome — Increased pressure within a closed muscle compartment that can impair perfusion.
• Capillary Refill — A bedside measure of peripheral perfusion after blanching the nail bed or skin.
