Which statement best describes the CMS mnemonic?

• A. It is a fixed set of vital signs
• B. It is used to measure blood glucose
• C. It is a mnemonic for neurovascular status
• D. It is a standalone trauma scoring system

Answer: (C)

The CMS mnemonic is a quick way to assess the neurovascular status of a limb after injury by looking at Circulation, Motor, and Sensation. It guides you to check circulation (pulse, color, temperature, capillary refill) to ensure there’s good blood flow; motor function (the patient’s ability to move the limb or digits) to assess nerve and motor integrity; and sensation (the patient’s ability to feel touch or pinprick) to evaluate sensory nerve function. This helps detect compromised perfusion or nerve injury early so you can act promptly. It isn’t describing vital signs, blood glucose, or a standalone trauma scoring system, which is why the neurovascular status interpretation is the best fit.
