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
|\ |\ |\ |\ |\ |\ |\ |\
