Final answer:
The neurological exam is used to assess the extent of function from the nervous system. It includes assessing pupils and using the Glasgow Coma Scale to evaluate neurologic status.
Step-by-step explanation:
The neurological exam is a clinical assessment tool used to determine the extent of function from the nervous system. It involves assessing various aspects of neurologic status, including pupils for equality, shape, and reactivity (PERRL) and the Glasgow Coma Scale (GCS) which assesses eye opening, verbal response, and motor response. By conducting these assessments, healthcare professionals can determine the level of neurologic function and identify any abnormalities or deficits.
