1. Which of the following diseases is associated with fewer acetylcholine
receptors, resulting in a lower-amplitude endplate potential, muscle
weakness, and fatigability?
- ANSWER Myasthenia Gravis
2. Which current multiple sclerosis drug treatments are designed to slow the
progress of myelin degeneration?
- ANSWER Immunomodulators
3. A nurse caring for a client with a spinal cord injury knows that control of
sweat gland activity and temperature regulation is managed by the direct
action of which body system?
- ANSWER Sympathetic Nervous System (SNS)
4. A 60-year-old male is being treated for significant denervation and muscle
fiber atrophy. His movements are still smooth and he has no cognitive
defects. Which likely diagnosis is associated with these clinical
manifestations?
- ANSWER ALS: A mixed UMN/LMN disorder
, 5. Components of a motor unit
- ANSWER Lower Motor Neuron
Neuromuscular junction
Skeletal muscle
6. Which organ found in muscle tendons transmits information about muscle
tension or force of contraction at the junction of the muscle and the tendon
that attaches to the bone?
- ANSWER Golgi tendon
7. Which cardinal assessment finding would lead the nurse to suspect a client
has developed Parkinson disease?
- ANSWER Bradykinesia
8. Which treatment should take place immediately in a client experiencing
autonomic dysreflexia?
- ANSWER place the client upright and correct the initiating stimulus (commonly
distended bladder or impacted bowels)
9. Which medication is used to treat acute attacks of multiple sclerosis (MS)?
- ANSWER Corticosteroids
10. Following a traumatic head injury from a severe blow to the back of the
head, a client is unable to maintain steady posture while in a standing
position, although the client is steadier when walking. Which brain
disorder most likely resulted from this injury?
- ANSWER A vestibulocerebellar disorder
11.The nurse is caring for a client with a spinal cord injury. Assessment reveals
shallow breath sounds with a very weak cough effort. The nurse correlates
this with which level of injury on the spinal column?
,- ANSWER C5
12.Throwing a ball or picking up a fork are movements controlled by which
portion of the frontal lobe?
- ANSWER Premotor cortex
13.The nurse is teaching a client at risk for intervertebral disk herniation about
common risk factors. Which risk factor(s) should the nurse include?
- ANSWER Having osteoarthritis of the spine
Lifting heavy objects while in a flexed position
Experiencing a fall or other trauma
14. A client is having difficulty controlling voluntary limb movements when
mobilizing. Based on these symptoms, the nurse focuses assessment on
which aspect of the nervous system?
- ANSWER Lateral brainstem pathways
15. Myelinated neurons found in the central nervous system are covered by
which type of cells?
- ANSWER Oligodendrocytes
16. After a spinal cord injury at S2-S4, most people experience constipation. Why
does this occur?
- ANSWER Defecation reflex is lost
In what part of the body does the highest level of motor function occur?
- ANSWER Frontal cortex of the brain
The friends and family members of a client who is being treated for a spinal cord
injury are troubled by the appearance of the client's abnormal flexion and muscle
spasticity. When explaining the reason for this phenomenon, the nurse should
describe:
, - ANSWER The client's muscle tone is no longer under the control of upper
motor neurons
Loss of coordinated movement, muscle rigidity, and immobility without paralysis
is likely due to damage to:
- ANSWER Extrapyramidal tracts
motor system anatomy - ANSWER upper motor neurons: project from motor
cortex in brain stem or spinal cord where they innervate lower motor neurons of
the contracting muscles
sensory feedback from the involved muscles that is continuously relayed from
cerebellum, basal ganglia, and sensory cortex
neuromuscular junction: links NS with muscle contraction
pyramidal motor system - ANSWER originates in motor cortex
provides control of delicate muscle movement
extrapyramidal system - ANSWER originates in the basal ganglia
provides background more more crude, supportive movement patterns
efficiency of movement of motor system depends on - ANSWER background
of muscle tone provided by stretch reflex and vestibular system input to maintain
stable postural support
