How does reviewing the genetic makeup of a client help
guide the PMHNP in selecting medication for clients? [
Ans: ] 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 [ Ans: ] 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.
,2
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 [ Ans: ] is composed of gray and white matter.
gray matter [ Ans: ] 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 [ Ans: ] associated with learning.
Changes in the gray matter are linked to psychiatric
diagnoses including Alzheimer's disease, schizophrenia,
and major depressive disorder.
White Matter [ Ans: ] contains nerve fibers that connect
neurons from different regions into functional circuits.
, 3
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? [ Ans: ] frontal
lobe from parietal lobe
Frontal lobe [ Ans: ] Associated with movement,
intelligence, abstract thinking. etc.
Broca's area [ Ans: ] Speech
Temporal lobe [ Ans: ] Involves object identification and
auditory signals
Cerebellum [ Ans: ] coordination and balance
