After application of restraints, how often should you check circulation, motor, and sensation in restrained limbs (CMS)?

• A. Every 15 minutes
• B. Every 30 minutes
• C. Every 60 minutes
• D. Every 5 minutes

Answer: (A)

Circulation, motor function, and sensation checks are performed every 15 minutes after restraints are applied to detect any early compromise from pressure or swelling. Restraints can create localized pressure, shift, or edema that reduces blood flow or irritates nerves, so frequent monitoring helps catch problems before they worsen. During each check, assess distal circulation (color, warmth, capillary refill), motor function (ability to move digits, grip strength), and sensation (numbness, tingling, or pain). If any CMS deficit or significant pain is noted, loosen the restraints to relieve pressure while maintaining safety, reassess promptly, and obtain further medical evaluation as needed. If perfusion remains compromised or nerve function is affected, seek additional assistance and continue close monitoring.
