CU NR 546 EXAM WITH CORRECT
ANSWERS 2025
How does reviewing the genetic makeup of a client help guide the
PMHNP in selecting medication for clients? correct answers >>
Genetic testing can assist by providing more information on how
clients may respond to certain psychotropic medications, as well
as providing information on how a client may break down and
metabolize medications based on the cytochrome P450 system.
There may be an environmental exposure that turned a gene "on"
that should have been "off" for one twin to develop schizophrenia
and not the other
. Both environmental and psychosocial stressors can impact
mental health. Although twins may have identical genes, their
gene expression may be different.
Neuroscience correct answers >> is the study of the
structure and function of the brain and is a field which is making
great advancements (Pliszka, 2016). A strong foundational
understanding of neuroscience and how the structure and
function of the brain can result in mental health symptoms is
necessary to treat mental illnesses.
Some mental disorders such as Alzheimer's disease,
schizophrenia, and major depressive disorder are thought to be a
result of malformations or malfunctions within the brain.
,The psychiatric mental health nurse practitioner (PMHNP) must
comprehend how medications impact the brain in order to safely
and effectively prescribe psychotropic medications.
Brain tissue correct answers >> is composed of gray and
white matter.
gray matter correct answers >> The cerebellum, cerebrum,
brain stem, and the butterfly-shaped portion of the central spinal
cord are comprised of gray matter which contains neural cell
bodies, axon terminals, dendrites, and all nerve synapses.
It is the working area of the brain and the focus of psychiatry and
neurology.
Gray matter correct answers >> associated with learning.
Changes in the gray matter are linked to psychiatric diagnoses
including Alzheimer's disease, schizophrenia, and major
depressive disorder.
White Matter correct answers >> contains nerve fibers that
connect neurons from different regions into functional circuits.
The myelin that coats neuronal axons is necessary for electrical
impulse transmission.
, Think of the white matter as a transit system. If there are breaks
in the system, then people cannot get to their destinations.
Within the brain, these breaks affect neural communication,
affecting behavior.
Damage to the myelin can impair transmission which can impact
not only sensory and motor function, but also cognition.
White matter abnormalities are associated with autism and
vascular dementia.
The central sulcus separates which lobes? correct answers >>
frontal lobe from parietal lobe
Frontal lobe correct answers >> Associated with movement,
intelligence, abstract thinking. etc.
Broca's area correct answers >> Speech
Temporal lobe correct answers >> Involves object
identification and auditory signals
Cerebellum correct answers >> coordination and balance
Wernicke's area correct answers >> Speech comprehension
