NURS 317 Final Questions and Infor With Correct
Solutions
True or False
Information is processed in the nervous system by transient changes in the electrochemical
gradient
True
They car known as action potentials and are always the same
Neural processing takes place at the _______
a. Soma
b. Axon
c. Dendrite
d. Synapse
d. Synapse
Neural processing is the process of summation of stimuli across the synapse.
The blood-brain barrier and the blood CSF barrier work to _____.
a. support the brain
b. maintain the electrolyte concentration
,c. provide bicarbonate ions
d. maintain a stable environment for neural function
d. maintain a stable environment for neural function
The nurse is caring for a client who has damage to the facial nerve (CN VII). What
complication related to unilateral loss of a branch of the facial nerve function should the
nurse closely assess for?
a. Loss of ability to accomodate
b. Eye dryness with risk for corneal scarring
c. Laryngeal obstruction
d. Unilateral, severe pain from inflammation of the nerve
b. Eye dryness with risk for corneal scarring
Loss of CN VII nerve function to damage can result in eye dryness with risk of corneal scarring
and blindness.
The student nurse has to evaluate the function of cranial nerve XII. Which techniques
would indicate that the student nurse needs further practice in correctly assessing cranial
nerve XII function? Select all that apply.
a. Note any deviation when the client sticks out the tongue.
b. Evaluate the client's ability to hear sound equally in both right and left ears.
,c. Observe for symmetry when the client opens her mouth and says "ahhh."
d. Evaluate the client's ability to say "fa-la-la" 3 to 4 times quickly.
b. Evaluate the client's ability to hear sound equally in both right and left ear.
c. Observe for symmetry when the client opens her mouth and says "ahhh"
d. Evaluate the client's ability to say "fa-la-la" 3 to 4 times quickly.
Having the client stick out their tongue and note any deviation to one side or the other are the
best techniques to observe CN XII.
The nurse is performing a test to determine a client's neurologic function related to a
suspected lesion in the parietal lobe. What would the nurse determine is a normal finding
after assessment?
a. The client is able to correctly distinguish visual cues.
b. The client is able to hear the words and repeat them to the nurse.
c. The client is able to determine correctly that the item placed in his hand is a paper clip.
d. The client is able to stand on both feet and put his finger to his nose.
c. The client is able to determine correctly that the item placed in his hand is a paper clip
, Localized lesions of the parietal lobe can result in the inability to recognize the meaningfulness
of an object (a condition called agnosia)
A client has sustained damage to cranial nerve VIII. The nurse recognizes that the client
may experience difficulty with:
a. Smell
b. Taste
c. Hearing
d. Motor
c. hearing
Cranial nerve VIII (vestibulocochlear nerve) is associated with hearing.
The nurse is working with a client who has an addiction to cocaine. The nurse is aware that
the "high" achieved by cocaine use is due to the inhibition of reuptake. What physiologic
phenomenon is affected?
a. The recycling of the drug, resulting in multiple stimulatory events
b. The resorption of the neurotransmitter to remove it from action
c. The recycling of the enzyme that inactivates dopamine
d. The inactivation of the postsynaptic receptor by invagination into the soma
