Treatment) with Complete Solutions
Serotonin (5HT) is a neurotransmitter associated with mood, sleep, and psychosis.
There are several serotonin receptors all over the human body. A unique aspect of the
second-generation antipsychotics is their ability to block 5HT2a receptors. What is the
effect of this inhibition? - ANSWER-A. Stabilizes dopamine concentrations in the CNS
B. Induces anxiety
C. Causes hallucination
D. Reduces platelet function
A is the correct answer
B. Represents antagonism of 5HT1a.
C. Represents a 5HT2a agonist
D Represents what happens when you inhibit SERT
Receptors trigger one of two effector pathways resulting in changes in neuronal activity.
These changes will, ultimately, effect gene expression. Which effector pathway is
characterized by ion flux through transmitter-activated channels resulting in an altered
membrane potential and neuronal activity?, - ANSWER-A. Slow effector pathways
B. Modulated effector pathways
C. Rapid effector pathways
D. NMDA glutamate receptor pathways
A. Represents G-coupled receptors
B. is fictitious
C. Is the correct answer
D. is a type of rapid effector pathway

steroids, cannabinoids, nitric pxide
C. glutamate, GABA, dopamine, serotonin, acetylcholine, endogenous opioids, nitric
oxide, cannabinoids, steroids
D. glutamate, GABA, dopamine, serotonin, norepinephrine, endogenous opioids,
steroids, histamine, nitric oxide
B is correct
, If a patient admits to taking his meds every other day (instead of daily, as Rx) a
potential concern would be: - ANSWER-A. Sufficient understanding or acceptance of
the illness
B. Abuse
C. Expense
D. is the desired effect recognized at a lower daily dose?
A. represents a patient taking his medication sporadically
B. represents taking too much
C. is the correct answer
D. represents a patient taking a lower than prescribed dose daily
The human brain is subcategorized into four major structures. These structures include
the cerebral cortex, brainstem, subcortical structures, and the cerebellum. Of these
major categories, which one houses the area of the brain that has been found in some
neuropathological studies of patients with schizophrenia to be of smaller size? -
ANSWER-A. Cerebral Cortex
B.Brainstem
C. Subcortical Structures
D. Cerebellum
the correct answer is C
Which neurotransmitter is considered the major excitatory neurotransmitter? -
ANSWER-A. Glycine
B. GABA
C. Glutamate
D. Serotonin
A & B are inhibitor and D is involved in mood and sleep
The correct answer is C
Neurotransmission is unidirectional insofar as chemical and electrical conduction is
concerned within the individual neuron. Which of the following descriptions best
characterizes the order of neurotransmitter/receptor interaction that results in an
electrical signal impulse and the release of another neurotransmitter for interaction in
the synaptic cleft (signal conduction through a neuron)? - ANSWER-A. Cell body,
dendrites, Axon and Axon terminals
B. Dendrites, Axon, Cell Body, Axon, Axon terminals
C.Dendrites, Cell body, Axon Axon terminals
D. Axon terminal, Axon, Cell body, Dendrites
G-protein coupled receptors are targets for several psychiatric medications. Given what
we know about these receptors, what is the ultimate result we will see when one of
