NURS 6630: Quiz 1 exam question/answer
graded A+ 2024/2025
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? - ✔️✔️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?, - ✔️✔️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
Which of the following consists of all the known major neurotransmitters that are
relevant in psychiatry? - ✔️✔️A. glutamate, GABA, dopamine, serotonin, norepi,
histamine, steroids, nitric oxide
B. Glutamate, GABA, dopa, NE, serotonin, ACTLCH, histamine, endogenous opioids,
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: - ✔️✔️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
Introducing adherence in facilitating treatment goals is something that would be
necessary in a patient who has previously displayed nonadherence patterns. - ✔️✔️False
It is introduced as early as possible in treatment to mitagate the risks associated with
non adhernece
Glia cells play a supportive role to the neuron. A few of the functions of the glial cells
include providing nutrition, maintaining homeostasis, stabilizing synapses, and
myelinating axons. The glial cells are categorized as microglia and macroglia. Of these
two cell types, which one plays an active and critical role in glutamatergic
neurotransmission by providing a co-agonist required for glutamate receptor function? -
✔️✔️A Microglial
B. Macroglial
B is correct
A. Microglial cells are small, phagocytic cells related to peripheral macrophages
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? - ✔️✔️A.
Cerebral Cortex
B.Brainstem
C. Subcortical Structures
D. Cerebellum
the correct answer is C
Which neurotransmitter is considered the major excitatory neurotransmitter? - ✔️✔️A.
Glycine
B. GABA
C. Glutamate
D. Serotonin
