Final answer:
If a child is intubated, unconscious, or preverbal, the most important part of the Glasgow coma scale is motor response.
Step-by-step explanation:
If a child is intubated, unconscious, or preverbal, the most important part of the Glasgow coma scale is motor response. The Glasgow coma scale is used to evaluate a child's level of consciousness and neurologic status, and it assesses eye-opening, verbal, and motor responses. However, when a child is unable to open their eyes, speak, or understand verbal instructions, the motor response becomes the most crucial indicator of neurological function.
