How does reviewing the genetic makeup of a client help guide the PMHNP in selecting medication for
v v v v v v v v v v v v v v v v
clients? - CORRECT ANSWER -
v v v v v
Genetic testing can assist by providing more information on how clients may respond to certain psycho
v v v v v v v v v v v v v v v
tropic medications, as well as providing information on how a client may break down and metabolize
v v v v v v v v v v v v v v v v
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
v v v v v v v v v v v v v v v v v v
to develop schizophrenia and not the other
v v v v v v v
. Both environmental and psychosocial stressors can impact mental health. Although twins may have id
v v v v v v v v v v v v v v
entical genes, their gene expression may be different.

Neuroscience - CORRECT ANSWER - v v v v
is the study of the structure and function of the brain and is a field which is making great advancemen ts
v v v v v v v v v v v v v v v v v v v v
(Pliszka, 2016). A strong foundational understanding of neuroscience and how the structure and fun ction of
v v v v v v v v v v v v v v v v
the brain can result in mental health symptoms is necessary to treat mental illnesses.
v v v v v v v v v v v v v v
Some mental disorders such as Alzheimer's disease, schizophrenia, and major depressive disorder are t
v v v v v v v v v v v v v
hought to be a result of malformations or malfunctions within the brain.
v v v v v v v v v v v v
The psychiatric mental health nurse practitioner (PMHNP) must comprehend how medications impact t he
v v v v v v v v v v v v v
brain in order to safely and effectively prescribe psychotropic medications.
v v v v v v v v v v
Brain tissue - CORRECT ANSWER -is composed of gray and white matter.
v v v v v v v v v v v
gray matter - CORRECT ANSWER -The cerebellum, cerebrum, brain stem, and the butterfly-
v v v v v v v v v v v v
shaped portion of the central spinal cord are comprised of gray matter which contains neural cell bodi es,
v v v v v v v v v v v v v v v v v
axon terminals, dendrites, and all nerve synapses.
v v v v v v v
, It is the working area of the brain and the focus of psychiatry and neurology.
v v v v v v v v v v v v v v
Gray matter - CORRECT ANSWER -associated with learning.
v v v v v v v
Changes in the gray matter are linked to psychiatric diagnoses including Alzheimer's disease, schizophr enia,
v v v v v v v v v v v v v v
and major depressive disorder.
v v v v
White Matter - CORRECT ANSWER - v v v v v
contains nerve fibers that connect neurons from different regions into functional circuits.
v v v v v v v v v v v
The myelin that coats neuronal axons is necessary for electrical impulse transmission.
v v v v v v v v v v v
Think of the white matter as a transit system. If there are breaks in the system, then people cannot ge t to
v v v v v v v v v v v v v v v v v v v v v
their destinations.
v v
Within the brain, these breaks affect neural communication, affecting behavior.
v v v v v v v v v
Damage to the myelin can impair transmission which can impact not only sensory and motor function, but
v v v v v v v v v v v v v v v v
also cognition.
v v
White matter abnormalities are associated with autism and vascular dementia.
v v v v v v v v v
The central sulcus separates which lobes? - CORRECT ANSWER -frontal lobe from parietal lobe
