When compartment syndrome is suspected, which action is appropriate to assess the pain level?

• A. Assist with splitting the cast
• B. Monitor urine output
• C. Evaluate pain using a pain scale
• D. Apply splints to the injured part

Answer: (C)

Evaluating pain using a pain scale is the most appropriate action because pain in suspected compartment syndrome is a key, subjective symptom that needs regular, objective tracking. A standardized scale lets you quantify how severe the pain is and monitor how it changes over time or in response to interventions. This helps you detect early improvement or worsening, which is crucial since escalating pain can indicate rising pressure and impending tissue compromise.

Other actions don’t directly quantify pain. Splitting the cast or applying splints are interventions to relieve external pressure but don’t provide a measurement of pain level. Monitoring urine output assesses risk of complications like rhabdomyolysis, not the current level of pain.
