Neurological Assessment Flashcards

1
Q

State how three different types of cells can cause different nervous system illnesses and what each cause?

A
  • infarctions (neurones which don’t received sufficient blood flow)
  • Multiple sclerosis (inflammation destruction and plaque affecting nerve impulse)
  • Tumours (cells of NS growth)

Q

What is the reticular activating system complex?
What does the complex allow for?

A

Network nerves extending from brain stem to forebrain, thalamus and cerebral cortex to receive sensory information

Greater sensory stimulation = greater alertness = greater consciousness

Q

Evaluate the AVPU method

A

Pros
- Simple, rapid and easy
- For trauma patients

Cons
- Only allows overview assessment not any causes or details
- Poor sensitivity to moderate impairment

Q

What score on the GCS requires escalation?

A

Any score below 8 as airways are compromised

Escalate if GCS changes by 2 or more (any change is a change)

Q

Evaluate the glasgow coma scale

A
  • Most reliable
  • Standardise neurological observations
  • Quick, easy, objective, reliable and accurate
  • Allow early changes in consciousness for treatment and management

Con
- Not as effective if symptoms like swelling to eyes that effect their ability to open

Q

Describe the GCS scoring method

A

Conciousness score
- 15 point score (8 or more escalate)
- For each section give best responses and only one

  1. Best eye opening - Start just visually, then talk to the patient, then response to pain (assessing the central nervous system)
  2. Best verbal response – Levels from whole conversations and no confusion to no sounds or audible noises)
  3. Best motor response – purposefully obeys to no response

Q

What can you use for a painful stimuli to assess best eye opening in a GCS?

A
  • Trapezius squeeze – caution in spinal injuries as pressure is applied
  • Supraorbital notch pressure – eyebrow/ above eyeball
  • Jaw angle pressure

Q

Explain the process of a checking a pupillary response
What is the normal response to pupillary response?

A
  • Assess cranial nerve 3
  • Each pupil must be assessed for shape, size and reaction to light
  • Shape – round
  • Size – equal sizes and generally 3-5mm
  • Reaction – react to light quickly, abnormal reactions are slow, sluggish or non reactive.

Q

What are some specific symptoms that should be escalated?

A
  • Visual fields and visual acuity – CN 2 optic nerve
  • Unable to open eyelid – CN 3 oculomtor nerve
  • Facial weakness – CN 7 facial nerve
  • Hearing loss – CN 8 – acoustic nerve
  • Gag and swallow deficits - CN 9 glossophrary nerve
17
Q

How would you do a motor and sensory assessment?

A
  • Limb motor power and sensation (each assessed individuals)
  • Use dermatology map to display where problems/ symptoms are in the body
  • Motor power – assess power and movement of each limb
  • Can differentiate between sides eg. Left severe and right normal

Categories
1. Normal 2. mild 3. severe 4. Abnormal flexion 5. Extension 6. nil movement

18
Q

What are the categories of motor and sensory assessment?

A
  • Normal (overcomes resistance applied can overcome gravity)
  • Mild (difficult overcoming resistance applied)
  • Severe (patient can not overcome resistance)
  • Abnormal flexion (abnormal movement where wrists externally rotate and arms flex inwards towards body)
  • Extension – abnormal movement where finger, wrists and arms externally rotate and straighten away from body
  • Nil – no movement
19
Q

What is a myoclonus?

A

brief involuntary twitching of muscle eg. Seizure

20
Q

What is a fasciculation?

A

involuntary muscle contraction and relaxation

21
Q

What is paralysis>

A

loss of motor movement

22
Q

What is a tic?

A

involuntary twitch of muscle

23
Q

What is a rest tremor?

A

coarse, slow movement

24
Q

What is an intention tremor?

A

worse with voluntary movement

25
Q

What is chorea?

A

sudden rapid jerky movements of limb

26
Q

What is atherosis?

A

slow, twisting writhing movements

27
Q

State the three different abnormal muscle tones?

A

Flaccidity – decreased muscle tone
Spasticity – increased tone
Rigidity – constant state of resistance eg. parkinsons

28
Q

What is a flaccidity muscle tone?

A

Decreased muscle tone

29
Q

What is spasticity muscle tone?

A

Increased tone

30
Q

What is rigidity muscle tone?

A

Constant state of resistance eg. parkinsons

31
Q

How would you do a sensory assessment?

A

Commonly associated with spinal conditions
Assess arms, trunk and legs for
- Normal sensation
- Pins and needles
- Numbness
- Hypersensitivity
- None

32
Q

How would you provide escalation if you were worried following a neurological assessment?

A
  1. Increased frequency of observations to 15 minute in deteriorating patients
  2. Escalate changes and concerns
  3. Prepare for further investigations or treatments eg, CT scan, MRI or pharmacological
