CU NR 546 EXAM WITH CORRECT -
ANSWERS /PASS GUIDE
1. 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.
2. 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.
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.
3. Brain tissue - -ANS☑️☑️--is composed of gray and white matter.
4. 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.
, 5. 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.
6. White Matter - -ANS☑️☑️--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.
7. The central sulcus separates which lobes? - -ANS☑️☑️--frontal lobe from parietal
lobe
8. Frontal lobe - -ANS☑️☑️--Associated with movement, intelligence, abstract
thinking. etc.
9. Broca's area - -ANS☑️☑️--Speech
10. Temporal lobe - -ANS☑️☑️--Involves object identification and auditory signals
11. Cerebellum - -ANS☑️☑️--coordination and balance
12. Wernicke's area - -ANS☑️☑️--Speech comprehension
