In single-starred criteria, what does letter D stand for?

• A. Disability
• B. Deformity
• C. Distress
• D. Dysfunction

Answer: (A)

In the START triage framework, the letters map to airway, breathing, circulation, and disability. The D stands for Disability, which gauges a casualty’s neurologic status and level of consciousness. Practically, you quickly check whether the person can follow simple commands or respond to voice or pain; if they are not responsive or cannot follow commands, they’re prioritized for immediate care. That’s why Disability is the correct interpretation of D. The other terms don’t fit this triage step: deformity refers to physical deformity, distress is a subjective feeling, and dysfunction isn’t the formal criterion used here.
