In a patient with a cast, which assessment is essential to monitor for compartment syndrome?

• A. Neurovascular checks
• B. Lung auscultation
• C. Temperature checks
• D. Skin turgor measurement

Answer: (D)

Swelling inside a cast can raise pressure in a closed muscle compartment, potentially cutting off blood flow and compressing nerves. The most important thing to monitor is the neurovascular status of the affected limb. Regular checks should focus on distal sensation and movement, color and temperature of the skin, capillary refill, and distal pulses, ideally compared with the other limb. Pain that is out of proportion or worsened by passive stretching, numbness or tingling, pallor, or weak/absent pulses are red flags for possible compartment syndrome. The other assessments (such as lung sounds, skin turgor, or general temperature) don’t assess this risk in the casted limb. If neurovascular changes are detected, act promptly by notifying the team and considering cast loosening or other interventions to relieve pressure.
