Why is it important to check distal pulses when immobilizing a limb?

• A. Check distal pulses before and after splinting
• B. Never check pulses
• C. Only check pulses if pain exists
• D. Check pulses only after evacuation

Answer: (A)

Monitoring blood flow to the injured limb is essential during immobilization. Distal pulses give a quick read on arterial perfusion beyond the injury. Checking them before splinting establishes a baseline so you know what normal perfusion looks like on that limb. Then rechecking after the splint is applied confirms you haven’t compromised circulation, since swelling or the way the splint fits can tighten and reduce blood flow. If pulses weaken or disappear after splinting, you know the splint is affecting circulation, so you should loosen or adjust it and proceed with evacuation if needed. This approach also helps you catch early signs of vascular trouble, like the limb feeling cool, pale, or numb, or difficulty moving the fingers or toes. In practice, conditions can change as swelling evolves, so both checks are necessary rather than relying on a single assessment.
