After splint application, which aspects of the limb should be reassessed?

• A. Temperature and swelling only
• B. Pulse and color only
• C. Circulation, Motor, Sensory (CMS)
• D. Pain level only

Answer: (C)

After splinting, the most important reassessment is Circulation, Motor, Sensory—CMS. This checks the limb’s neurovascular status to detect any new or worsening problems caused by the injury or the splint itself.

Circulation: look at distal pulses, color, warmth, and capillary refill to ensure blood flow hasn’t been restricted. Poor circulation can lead to tissue damage if not caught early.

Motor: assess whether the person can move the toes or fingers or move the limb distal to the injury. Loss of movement may indicate nerve or muscle compromise or increasing swelling.

Sensory: check for sensation—such as light touch or pinprick—and note any numbness or tingling. Changes here can signal nerve compression.

Together, these checks help you act quickly if the splint is too tight or swelling is compromising the limb, such as loosening the splint or seeking further medical care.

Relying on temperature and swelling alone may miss evolving nerve or perfusion problems; focusing only on pulses and color misses motor and sensory function; checking pain alone doesn’t reveal neurovascular status. CMS provides a complete view of the limb’s condition.
