MN 551 Unit 9 Chapter 13, 15, 16, 17, 18
The nurse knows that which of the following phenomena listed below is an accurate
statement about axonal transport - ANS-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 - ANS-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 - ANS-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 - ANS-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? - ANS-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 -
ANS-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 -
ANS-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 - ANS-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 - ANS-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? - ANS-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 damaged? - ANS-The outer layer (neolayer)
Not realizing that it's surface was hot a woman has quickly withdrawn her hand from the
surface of a bowl that she was removing from a microwave. Which of the following
phenomena has facilitated the rapid movement of her hand in response to the painful
stimulus? - ANS-Her CNS has an acted a productive response received by neurons that
innervate her arm muscles
A taekwondo master is applying downward pressure just above the elbow joint on an
attacker who immediately collapses to the ground. The taekwondo master knows the
elbow joint can bend inward toward the body but not in the opposite direction. Which of
the following reflexes is applicable to this example - ANS-Inverse myotatic
During a clinical assessment of a 68-year-old client who has suffered a head injury a
neurologist suspects that a client has sustained damage to her Vegas nerve (CN 10).
Which of the following assessment findings as most likely to lead the physician to this
conclusion? - ANS-The client has difficulty swallowing and has had a recent
constipation and hypo active bowel sounds
A nine year old girl has a diffuse collection of symptoms that are indicative of deficits in
endocrine and autonomic nervous system control. She also suffers from persistent fluid
and electrolyte in balance. The nurse knows which of the following aspects of the
nervous system listed below with her healthcare providers focus their diagnostic efforts
on? - ANS-Impaired function of her hypothalamus
