ObjectivesAfter completion of this self paced course you will be able to:
• Describe how the neurological assessment process has changed:
– The mental status aspects of central nervous system function was relocated to a separate form.
– The neurological screen was redesigned to focus on systematically assessing central and peripheral nerve function.
• Demonstrate how to appropriately conduct a neurological assessment using the following defined parameters:
– Pupils/Vision– Neuromuscular Movement– Sensation– Speech – Swallow
• Verbalize when to use additional assessment parameters and the “Neuro Check-Frequent” screening process.

Why Change the Neurological Assessment?
• Patients benefit when caregivers use a comprehensive, evidence-based framework to evaluate and detect subtle changes. The new screens focus on assessing central and peripheral nervous system function to detect abnormalities in sensation and movement.
• By using this approach, caregivers will:- Communicate more effectively - Collaborate to diagnose and treat problems early- Improve patient outcomes

Current Neurological Assessment• Mental status parameters are currently assessed in two screens
– Mental Status and Neurological. • All of the mental status parameters are being moved to the
Mental Status section to support nursing evaluation.• Physical exam references were used to update the neurological
assessment with comprehensive parameters.
![Page 5: Overview: Technical contact: Content contact: If you have technical questions please contact the Service Desk 414-647-3520 in Milwaukee or 1-800-889-9677](https://reader035.vdocuments.mx/reader035/viewer/2022062714/56649d165503460f949eb7b1/html5/thumbnails/5.jpg)
Assessing Neurological Status
• Monitor for subtle indications of neurological changes during conversation.
• Evaluate pupils in ambient room light.
• Muscles with intact nerve function move and relax voluntarily with a slight residual tension known as muscle tone and no abnormal movements.
• Prepare patients who have actual or potential neurological changes that the nurses may test their sensation and ability to move, talk, and swallow more often and not to worry

Parameter Defined Limits (WDL)
Pupils/Vision Equal, normal size (2-6 mm), round shape, and reactive with vision per patient’s baseline, and no extra-ocular muscle movements.
Neurological Movement
Moves all extremities with equal strength*. Absence of involuntary movements.
Sensation: Reports normal sensations throughout body, no paresthesias.
Speech: Verbalization is clear and understandable
Swallow: Swallowing without coughing, choking, tearing on liquids and / or solids.
Purple text indicates new content
*Note actual strength is evaluated in the musculoskeletal section

Neurological Assessment
The revised neurological assessment parameters provide a framework for evaluating changes in central (cranial) and peripheral nerve function.
• Pupils/ Vision
• Sensation
• Neurological movement
• Speech
• Swallow
![Page 8: Overview: Technical contact: Content contact: If you have technical questions please contact the Service Desk 414-647-3520 in Milwaukee or 1-800-889-9677](https://reader035.vdocuments.mx/reader035/viewer/2022062714/56649d165503460f949eb7b1/html5/thumbnails/8.jpg)
Pupils and Vision
• Pupil evaluation is a necessary neurological assessment parameter.
• Normal pupil sizes ranges from 2-6mm. It is easy to see if abnormal size: <1 or >6 mm.
• Pupil size and reactivity can be evaluated in ambient room lighting.
• Use a flashlight for more brisk response if vision or neurological abnormality is suspected.
• Note: Abnormal pupil function seldom occurs alone in patients who appear to be interacting normally.
