Week 1 quiz
Hello NR546 students,
In order to provide feedback on the weekly quizzes, I will provide rationale
statements for the quiz questions. You will note that there are more than 5
listed this is because the quiz testbank is larger than 5 questions and the
additional information can help you prepare for the final and direct your
study.
The amygdala is associated with anxiety and perception of odors.
The hippocampus is involved in memory and anxiety. The amygdala is
associated with anxiety and perception of odors. The prefrontal cortex
is associated with executive function. The thalamus is associated with
motor command processing
The client’s cognitive status can result in an ethical concern if the
client is unable to self-determine care or is a danger to self or others.
Ability to pay is not an ethical issue.
basal ganglia are a group of structures involved in voluntary motor
movements. Basal ganglia are also involved in cognition and emotion.
Limbic system is associated with emotion and learning
hippocampi are associated with long term memory
Wernicke's area is associated with speech comprehension. Review
activity
the dorsolateral prefrontal cortex (DLPFC) is concerned with higher
level functioning. The VLPFC is involved with motor inhibition the IFG
contains Broca's area which is associated with speech production
understanding grammar. Pliska Ch. 8
the OFC is involved in decision making and social behavior with a focus
on punishment and rewards. The OFC inhibits and activates the
amygdala and is activated when a risk assessment is required. Some
behaviors associated with the OFC include sex, sugar, pain, social
humiliation, money, rewards, fame, and aggression. The amygdala will
identify a threat and then the OFC will determine the risk or benefit of
an action based on past experience. Pliska Ch. 8, p.158
At this time, 20 % of the world’s population is suffering from a
neurologic and/or psychiatric disorder.

Hello NR546 students, here are some clinical pearls and quiz bank rationales
for you.
G protein linked systems, one of the signal transduction cascades, pass
the message from a first receptor to a second messenger .
Glutamate is an excitatory neurotransmitter. (NEI glutamate video- the
glutamate sisters)
CYP 3A4 is one of the 5 most important NT which include CYP 1A2,
2D6, 2C9, 2C19, 3A4. Dosing adjustments may be required. Stahl p.
46-51.
Smoking induces CYP1A2. Stahl p.48
partial agonist- drug does not fully activate receptors; antagonist- drug
binds to receptor but does not activate a response; inverse agonist-
drug cause opposite effect of the agonist ;agonist- ;agonist- drug
binds to the receptor and activates a biological response
G protein Linked systems and ion channel linked cascades are
triggered by neurotransmitters. Stahl p. 11
Propagation of an action potential to the axon terminal is mediated by
voltage-sensitive sodium channels. Influx of sodium through voltage-
sensitive sodium channels at the axon terminal leads to opening of
voltage-sensitive calcium channels, also at the axon terminal. Influx of
calcium through the open voltage sensitive calcium channels leads to
docking of synaptic vesicles and secretion of neurotransmitter into the
synapse.
Agonists cause ligand-gated ion channels to open more frequently.
The communication between neurons at synapses is mediated by
neurotransmitter molecules and is therefore chemical. Stahl p. 6
Transcription factors are proteins that bind to promoter sequences of
DNA to turn gene expression on and off.
chemical neurotransmission is the foundation of psychopharmacology
