True or false?
•
Acetylcholinesterase stimulates the release of acetylcholine (ACh). - -----ANSWER---->False.
Rationale: Acetylcholinesterase breaks down ACh, resulting in relaxation of the skeletal muscle.
After being thrown off the back of a bull, a bull rider can move his arms but has loss of motor function in
the lumbar and sacral segments of the spinal cord. This is referred to as:
a. Tetraplegia
b. Quadriplegia
c. Paraplegia
d. Anterior cord syndrome - -----ANSWER---->c. Paraplegia
What disease results from the degeneration of the dopamine nigrostriatal system of the basal ganglia?
a. Parkinson disease
b. Huntington disease
c. Guillain-Barré syndrome
d. Myasthenia gravis - -----ANSWER---->a. Parkinson disease
,Which disease is a result of basal ganglia dysfunction?
A.Myasthenia gravis
B.Multiple sclerosis
C.Polio
D.Tourette syndrome - -----ANSWER---->D. Tourette syndrome
Rationale: The tics and hyperkinesia that often accompany Tourette syndrome are typical of basal
ganglion dysfunction (the function of the basal ganglia is movement control).
Which disorder is caused by damage to both upper and lower motor neurons?
A.ALS
B.MS
C.Myasthenia gravis
D.Parkinson - -----ANSWER---->A. ALS
Rationale: Also known as Lou Gehrig disease, ALS is the result of damage to both upper and lower motor
neurons. Typical S/S include weakness, lack of motor control, denervation atrophy, and hyporeflexia.
Which two substances are needed by the mitochondria in order to produce ATP?
A.O2 and CO2
B.Glucose and O2
C.Glucose and fatty acids
D.Proteins and monosaccharides - -----ANSWER---->B. Glucose and O2
Rationale: Glucose and oxygen are necessary for ATP production. Without ATP, no physiologic work can
be done—the cells, and eventually the organism, will die. When oxygen is not available, anaerobic
pathways are used, creating lactic acid that also damages the cell.
True or false?
•
, Increased ICP results in primary brain injury. - -----ANSWER---->False
•
Rationale: Increased pressure in the brain leads to secondary brain injury (there is nowhere for the
pressure to be released because the brain is encased in bone). Primary brain injury is caused by trauma.
All of the following are true EXCEPT:
a. Increased ICP can cause herniation and hydrocephalus
b. Ischemia is the most common cause of primary brain injury
c. Hematomas result from vascular injury and bleeding
d. Concussion is defined as a transient neurogenic dysfunction caused by mechanical force to the brain -
-----ANSWER---->b. Ischemia is the most common cause of primary brain injury
The CT scan report identified that a client with a skull fracture has developed a hematoma that resulted
from a torn artery. The report would be interpreted as:
Subdural hematoma
Intracranial hematoma
Chronic subdural hematoma
Epidural hematoma - -----ANSWER---->Epidural hematoma
A teenager has been in a car accident and experienced an acceleration-deceleration head injury. Initially,
the client was stable but then started to develop neurological signs/symptoms. The nurse caring for this
client should be assessing for which type of possible complication?
a. Brain contusions and hematomas
b. TIAs and cerebrovascular infarction
c. Momentary unconsciousness
d. Status epilepticus - -----ANSWER---->a. Brain contusions and hematomas
Following a collision while mountain biking, the diagnostic work up of a 22-year-old male has indicated
the presence of an acute subdural hematoma. Which pathophysiologic process most likely underlies his
diagnosis?
a. Blood has accumulated between the man's dura and arachnoid.
