QUESTIONS AND ANSWERS
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.
White matter abnormalities are associated with autism and vascular dementia.
The central sulcus separates which lobes? - CORRECT ANSWER-frontal lobe from
parietal lobe
Frontal lobe - CORRECT ANSWER-Associated with movement, intelligence, abstract
thinking. etc.
Broca's area - CORRECT ANSWER-Speech
Temporal lobe - CORRECT ANSWER-Involves object identification and auditory signals
Cerebellum - CORRECT ANSWER-coordination and balance
Wernicke's area - CORRECT ANSWER-Speech comprehension
occipital lobe - CORRECT ANSWER-Primary visual area
parietal lobe - CORRECT ANSWER-Keeps us alert to what is going on around us
Sensory Cortex - CORRECT ANSWER-Pain, heat, and other sensations
motor cortex - CORRECT ANSWER-Movement
Hippocampus - CORRECT ANSWER-Involved in both memory and anxiety
