NURS 3320 EXAM 3 QUESTIONS AND ANSWER
Chapter 25 Neuro Assessment - CORRECT ANSWER✅✅
Describe each cranial nerve - CORRECT ANSWER✅✅1. CN 1 (Olfactory)= smell impulses from nasal
mucosa to brain
2. CN2(optic)= snellen chart, retina and optic disk, stim from eye to brian
3. oculomotor, trochlear, abducens (3,4,6)= assess with 6 carinal field of gaze
CN5 (trigeminal): clench teeth, nurse palps tmj and masseter for bilat contraction
-abnorm:decreased contraction,
-sensory test: sharp vs soft, corneal reflex-blinking bilaterally
CN7 (Facial): sym face movement when smiling, frowning, show teeth, puff cheeks, purse lips, raise
eyebrows, close eyes
CN8 (acoustic/vestibulocochlear): weber test- vibration equal, Rinne test-air conduction is twice as long
as bone conduction
CN 9 and 10 (glossopharyngeal and vagus): cn10- ahhh for sym uvula soft palate rise, cn9 or 10: gag
reflex
-Vagus: slow hrt rate with valsava mvmt
CN11 (spinal accessory)= innervates neck, mvmt of shoulders, head rotation, larynx
CN12 (hypoglossal)= innervates tongue, mvmt of food/talk

List all the spinal Nerves - CORRECT ANSWER✅✅- 8 cervical
- 12 thoracic
- 5 lumbar
- 5 sacral
- 1 coccygeal
*Innervate dermatomes
Describe the components of the ANS - CORRECT ANSWER✅✅1. Sympathetic= fight or flight
*Fibers= Thoracomlumbar level (t1 and L2 of spinal cored
2. Parasympathetic=
*Fibers= craniosacral regions (s1-s4 and CN 3,VI, IX, X)
How do you rate reflexes? - CORRECT ANSWER✅✅Hyporeactive (0): lower motor neurons or reflex arc
is impaired (spinal cord inj)
Hyperactive(+4): lesions on upper motor neurons and when high cortical levels are impaired (
What is clonus and how does it show up on a patient - CORRECT ANSWER✅✅-Rapid contraction or
oscillations of foot
-shaking of foot, check if reflexes are hyperactive,
-dorsiflex pt foot toward pt and observe for any rapid beats of the foot
-indicates lesions to the upper motor neurons
How do you test for meingitis? - CORRECT ANSWER✅✅-place hands behind pts head, flex neck foward
as far as the pt can tolerate,
,-Meningeal infection: pain is present in the neck and resistance is felt on flexion
-Positive brudzinski sign: pain and flexed hips and knees as you assess flexion of head
*flex neck, observe movement in hips and knees
-positive kernig: pain and resistance with extension of knees, bilateral,
*Flex leg at bothe the hip and knee then straighten knee
How do you assess for LOC/orientation - CORRECT ANSWER✅✅ask: place, time, date, reason here
*alert and oriented x4
Review table 25-1 - CORRECT ANSWER✅✅1. frontal lobe: comms, speech, emotions
-primary motor cortex, voluntary mvmt, broca area (speech), reasoning, judgement
2. parietal lobe: sensation
-primary sensory cortex, touch, pain, temp, 2 point discirmination
3. occipital lobe: vision, primary visual receptor center
4. temporal lobe: auditory
Wernicke area= interprets auditory stim
Review Abnormal findings 25-2 - CORRECT ANSWER✅✅1. Amyotrophic lateral sclerosis: atrophy and
fasciculations of tongue in pt
2.Eye Tic
-winging, gramacing, shoulder srugging (tics)
-causes: tourettes, drugs (amp, phenothia)
3. Choreiform mvmts of hand
, -brief, rapid, jerky, irregular, and unpredictable, The face, head, lower arms, and hands are often
involved
-Causes: sydenham chorea w/ rheumatic fever and huntington dz
4. resting tremors:
-disappear with movemnt
-pill rolling (parkinsons
5. Postural tremor
-part of body actively tryinhg to maintain posture
-hyperthy, anx, fatigue,
6. Athetosis
-larger amplitude. They most commonly involve the face and the distal extremities
-Cerebral palsy (cause)
7. Intention tremor of pointed finger
-cerebellar pathway disorder (MS)
-absent at rest
-appear with activity .
What is sterognosis - CORRECT ANSWER✅✅1. patient can tell shape, size or details of object
What is graphesthesia? - CORRECT ANSWER✅✅1. patient can tell what number is written on hand with
their eyes cloed
Review age-related changes - CORRECT ANSWER✅✅1. diminished ability to detect vibrations
2. difficulty performing rapid alternating movements due to decreased reaction time and flexibility, may
see tremors with intentional movements
3. slow response of DTR
