In the trauma primary survey, what does 'C' assess?

• A. exposure and environmental control
• B. disability (AVPU/GCS)
• C. airway management
• D. breathing

Answer: (B)

Circulation. This step focuses on perfusion and stopping life-threatening bleeding. During the C phase, you rapidly identify and control any severe hemorrhage, establish rapid IV or IO access for resuscitation, and assess perfusion by noting pulse quality, blood pressure (if obtainable), skin color and temperature, and capillary refill. The goal is to restore and stabilize circulation quickly while continuing to reassess response to interventions.

Disability (neurologic status using AVPU or GCS) is evaluated after circulation, as part of the next step in the sequence.
