◉ 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. Answer: 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. Answer: 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. Answer: 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?.
Answer: 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. Answer: 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. Answer: 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. Answer: 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. Answer:
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?. Answer:
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?. Answer: 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?. Answer: 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. Answer: 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?. Answer: The client
