Which component of the ATCN primary survey evaluates neurological status?

• A. Airway with cervical spine protection
• B. Breathing
• C. Circulation
• D. Disability (neuro status)

Answer: (D)

Disability (neuro status) is the part of the ATCN primary survey that quickly assesses brain function. It examines mental status, level of alertness, orientation, and brief neurologic checks such as pupil size/reactivity and limb movement to detect deficits. This direct look at neurological function helps identify potential brain injury or systemic factors affecting the brain, guiding urgent actions like airway protection or rapid neuro evaluation. The other components address airway with cervical spine protection, breathing, and circulation, which are about airway patency, ventilation, and perfusion, not brain function. So evaluating neurological status falls under Disability.
