RN Neurological System Assessment

Nurse performing a neurological assessment on a patient

A registered nurse (RN) neurological system assessment is a standardized evaluation of a patient's brain and nervous system function, using specific tests to detect abnormalities.

How It Works

The assessment follows a structured process:

Orientation: The nurse asks the patient about person, place, and time to assess mental status.
Motor Function: Tests include muscle strength, tone, and coordination (e.g., asking the patient to walk, raise arms, or perform finger-to-nose movements).
Sensory Function: The nurse evaluates the patient's ability to feel touch, pain, and temperature in different body areas.
Reflexes: The nurse tests deep tendon reflexes (e.g., knee jerk) using a reflex hammer.
Cranial Nerves: The nurse assesses the function of the 12 cranial nerves (e.g., vision, hearing, facial movement, swallowing).

Main Types of Assessments

RNs use several types of neurological assessments, including:

Type	Description	Example
Mini-Mental State Examination (MMSE)	Brief screening tool for cognitive impairment	Asking the patient to name objects, repeat phrases, and follow commands
Glasgow Coma Scale (GCS)	Assesses conscious state in trauma or emergency patients	Scoring eye-opening, verbal response, and motor response
National Institutes of Health Stroke Scale (NIHSS)	Evaluates stroke severity and progression	Testing speech, language, and motor function

When and Why It's Used

RNs perform neurological assessments during initial patient encounters, follow-up visits, and when changes in neurological status occur. These evaluations help detect conditions like stroke, seizures, or traumatic brain injury early.

For example, if a patient reports sudden numbness or weakness, the RN performs targeted assessments to locate the affected area and determine the cause.

Common Misconceptions

Many people confuse neurological assessments with psychological evaluations. While both assess brain function, neurological assessments focus on physical aspects like reflexes and sensory responses, whereas psychological evaluations examine mental health and behavior.

Another misconception is that only doctors can perform these assessments. In reality, RNs with proper training conduct them routinely in hospitals, clinics, and home care settings.

Firsthand Experience

During my clinical rotations, I observed an RN performing a neurological assessment on a post-surgical patient. The nurse checked reflexes, tested sensory responses, and asked the patient to follow simple commands. This thorough evaluation helped identify a potential complication early, allowing for prompt intervention.
