exam questions with answers |\ |\ |\
The nurse knows that which of the following phenomena
|\ |\ |\ |\ |\ |\ |\ |\ |\
listed below is an accurate statement about axonal
|\ |\ |\ |\ |\ |\ |\ |\
transport - CORRECT ANSWERS ✔✔Materials can be
|\ |\ |\ |\ |\ |\ |\
transported to the nerve terminal by either a fast or slow|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
component
An adult male has a new diagnosis of Guillain Barre
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
syndrome. The nurse knows which of the following |\ |\ |\ |\ |\ |\ |\ |\
pathophysiological processes underlie the deficits that |\ |\ |\ |\ |\ |\
accompanied the degeneration of myelin in his peripheral |\ |\ |\ |\ |\ |\ |\
nervous system - CORRECT ANSWERS ✔✔Unless re-
|\ |\ |\ |\ |\ |\ |\
myelination occurs the axon will eventually die |\ |\ |\ |\ |\ |\
While assessing a critically ill patient in the emergency
|\ |\ |\ |\ |\ |\ |\ |\ |\
department the nurse notes on the cardiac monitor an R |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
on T premature ventricular beat that develops into
|\ |\ |\ |\ |\ |\ |\ |\
ventricular tachycardia. Immediately the patient became
|\ |\ |\ |\ |\ |\
unresponsive. The nurse knows that based on the |\ |\ |\ |\ |\ |\ |\ |\
pathophysiologic principles the most likely cause of this |\ |\ |\ |\ |\ |\ |\ |\
unresponsiveness is - CORRECT ANSWERS ✔✔Interruption |\ |\ |\ |\ |\
of the blood/oxygen supply to the brain
|\ |\ |\ |\ |\ |\ |\
,When educating a patient about to undergo a pacemaker
|\ |\ |\ |\ |\ |\ |\ |\ |\
insertion the nurse explains the normal phases of cardiac
|\ |\ |\ |\ |\ |\ |\ |\ |\
muscle tissue. During the repolarization phase the nurse
|\ |\ |\ |\ |\ |\ |\ |\
will stress that the membranes must be re-polarized
|\ |\ |\ |\ |\ |\ |\ |\
before they can be re-excited. Within the cell the nurse
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
understands that - CORRECT ANSWERS ✔✔Potassium |\ |\ |\ |\ |\ |\
channels open while sodium channels close causing |\ |\ |\ |\ |\ |\ |\
repolarization to the resting state |\ |\ |\ |\
A client with a diagnosis of depression has been
|\ |\ |\ |\ |\ |\ |\ |\ |\
prescribed a medication that ultimately increases the |\ |\ |\ |\ |\ |\ |\
levels of neurotransmitter serotonin between neurons.
|\ |\ |\ |\ |\ |\
Which of the following processes will accompany the
|\ |\ |\ |\ |\ |\ |\ |\
actions of the neurotransmitter in a chemical synapse? -
|\ |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔More neurotransmitters will cross |\ |\ |\ |\ |\ |\
the synaptic cleft's and bond with postsynaptic receptors
|\ |\ |\ |\ |\ |\ |\
The Neurotransmitter GABA Mainly functions to trigger
|\ |\ |\ |\ |\ |\ |\
inhibitory postsynaptic potential. Therefore when |\ |\ |\ |\ |\
explaining this to a group of nursing students the nurse |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
will state that - CORRECT ANSWERS ✔✔The combination
|\ |\ |\ |\ |\ |\ |\ |\
of GABA with the receptor site is inhibitory since it causes
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
the local nerve membrane to become hyper polarized and
|\ |\ |\ |\ |\ |\ |\ |\
less excitable
|\ |\
When reviewing the purpose/action of neurotransmitters
|\ |\ |\ |\ |\ |\
as they interact with different receptors the nurse
|\ |\ |\ |\ |\ |\ |\ |\
instructor gives an example using acetylcholine. When |\ |\ |\ |\ |\ |\ |\
, Acetylcholine is released at the SA node in the right |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
atrium of the heart it is - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\ |\
✔✔Inhibitory
A mail newborn infant has been diagnosed with spina
|\ |\ |\ |\ |\ |\ |\ |\ |\
bifida occulta. Which of the following pathophysiological
|\ |\ |\ |\ |\ |\ |\
processes has most likely contributed to the infants |\ |\ |\ |\ |\ |\ |\ |\
health problem - CORRECT ANSWERS ✔✔The neural
|\ |\ |\ |\ |\ |\ |\
groove failed to fuse and completely close across the top
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
of the neural plate
|\ |\ |\
A child is experiencing difficulty with chewing and
|\ |\ |\ |\ |\ |\ |\ |\
swallowing. The nurse knows that which of the following |\ |\ |\ |\ |\ |\ |\ |\ |\
cells may be innervating specialize got related receptors
|\ |\ |\ |\ |\ |\ |\ |\
that provide taste and smell - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\
✔✔Special visceral afferrent cells |\ |\ |\
A nursing student having trouble moving his head from
|\ |\ |\ |\ |\ |\ |\ |\ |\
side to side is likely experiencing a problem with which
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
type of neurons? - CORRECT ANSWERS ✔✔Pharyngeal
|\ |\ |\ |\ |\ |\ |\
efferent neurons. |\
Following a spinal cord injury suffered in a motor vehicle
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
accident a 22-year-old male has lost fine motor function
|\ |\ |\ |\ |\ |\ |\ |\ |\
of his fingers and thumb but is still able to perform gross
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
motor movements of his hand and arm which of the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
following components of his white matter have likely been
