CU NR 546 Exam Questions with
Correct ANSWERS | Latest Update
100% PASS
How does reviewing the genetic makeup of a client help guide the PMHNP in
selecting medication for clients? - CORRECT ANSWER-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 ANSWER-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 ANSWER-is composed of gray and white matter.
gray matter - CORRECT ANSWER-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 ANSWER-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 ANSWER-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.
