Instructions on how to navigate this course.This course does not have sound.

Features:

This course is the second of a two part series to update the physical assessment screens at Aurora. Participants will learn how to systematically assess central and peripheral nervous system function in ICU and non-ICU patients and document findings in the electronic health record to detect and monitor changes over time.

New & Improved Physical Assessment: Neurological

Page 2: Neurological assessment (PowerPoint presentation)

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.

Page 3: Neurological assessment (PowerPoint presentation)

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

Page 4: Neurological assessment (PowerPoint presentation)

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: Neurological assessment (PowerPoint presentation)

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

Page 6: Neurological assessment (PowerPoint presentation)

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

Defining “Normal” (WDL) for Neurological Status

Page 7: Neurological assessment (PowerPoint presentation)

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: Neurological assessment (PowerPoint presentation)

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.

Page 9: Neurological assessment (PowerPoint presentation)

Reference Text

• Reference Text is provided to tell you how to evaluate and define vision and extraocular muscle movement abnormalities (and most of the other parameters).

• Right click on the column header of the grid (green row) and view the reference text.

Page 10: Neurological assessment (PowerPoint presentation)

Double vision may occur because of problems with the optic nerve (vision) or as a problem in the muscles of the eye that focus vision.

Refer to Reference Text for directions about how to assess to determine the difference.

Pupils and Vision Reference Text

Page 11: Neurological assessment (PowerPoint presentation)

Neurologic Assessment: Movement

• The presence of abnormal neurologically-based movement and muscle tone is assessed in this section.

• It also captures the presence of any neurologically-based involuntary movements including posturing.

The Reference Text provides assessment directions and term definitions.

Page 12: Neurological assessment (PowerPoint presentation)

Neurological Assessment: Movement

• Loss of symmetrical movement or tone is documented by selecting the appropriate descriptor for each extremity

• The evaluation of muscle strength continues to be documented in the Musculoskeletal Section of Physical Assessment

Page 13: Neurological assessment (PowerPoint presentation)

Neurological Assessment: Sensation

Abnormal Sensation is evaluated by location & type:

• Numbness (loss of sensation)

• Tingling/Burning/Crawling (hyper-sensation)

• Unable to Distinguish meaning a loss of certain types of sensation

Page 14: Neurological assessment (PowerPoint presentation)

Neurological Assessment: Speech & Swallow• New assessment descriptors have been added.• The ability to consult nutrition services and speech

therapy will remain.

Page 15: Neurological assessment (PowerPoint presentation)

Additional Parameters Include:

• Intermittent Loss of Normal Neurological Function– Dizziness– Fainting/Loss of Consciousness– Blackout– Seizure Assessment

• Neurological Standardization Measurement Scales– Dysphagia Screen for Stroke Symptoms – Glasgow Coma Scale– Hunt and Hess Subarachnoid Stroke Scale– Modified Parkinson’s Assessment Form– National Institutes of Health Stroke Scale (NIHSS)

Page 16: Neurological assessment (PowerPoint presentation)

Dysphagia Screen for Stroke Symptoms

• The System Stroke Committee recommended the use of this tool to screen for dysphagia related to stroke.

• Use of this tool by nurses varies across the system and is dependant upon resources available to do a dysphagia screen.

Page 17: Neurological assessment (PowerPoint presentation)

Neurological Assessment: Seizure

• The Seizure section was revised to allow for more specific documentation of seizure activity.

• Seizures are classified based on symptoms and test findings about the location in the brain. Reference text about what the classification means is available.

• Document as Unknown, unless you work in an area that classifies.

Page 18: Neurological assessment (PowerPoint presentation)

Frequent Neuro Checks

• The Neuro Check – Frequent form is designed for patients who need frequent neurological assessments after a stroke, head trauma, or neurosurgery.

• The Neuro Check – Frequent form briefly screens for altered mental and neurological status. Complete a comprehensive system assessment if changes occur that are not reflected on this form.

Page 19: Neurological assessment (PowerPoint presentation)

Reviewing Findings in the GenViews

• The most recent values for each assessment parameter appear in the GenViews.

• Note: Findings post with the date and time that it was recorded. Data may come from different forms.

Page 20: Neurological assessment (PowerPoint presentation)

Remember: The Nursing Flowsheet is the Best Method to Trend Parameters over Time

Page 21: Neurological assessment (PowerPoint presentation)

Summary of the Improvements

• Mental status parameters were moved to their own section to support comprehensive patient assessment.

• The Neurological Assessment process was updated to provide nurses with a framework for evaluating changes in central and peripheral nerve function:

– Pupils/Vision were added to the defined normal section along with other neurological parameters including movement, sensation, speech, & swallow.

– The additional parameters section was updated to improve patient assessment (e.g. dysphagia, seizures, etc.)

4. Which of the following statements about the Neuro Check, Frequent form is true?

– The form is designed as a screening tool after a stroke, head trauma, or neurosurgery.

– The form contains both mental status & neurological assessment parameters.

– If the patient becomes disoriented, the nurse documents it on the Neuro Check-Frequent form and completes a Mental Status Assessment before calling the physician.

– The form screens for changes in LOC, pupils/vision, movement, and speech; Charting a Glasgow Coma Scale with the same parameters would be duplication.

– All of the above Answer: e
