UT Arlington NURS 5410 Exam 1 (pdf) | 2026/2027 | Intro to Psych
Mental Health Q&A | Psychiatry
1. Which of the following best describes the primary focus of NURS 5410:
Introduction to Psychiatric Mental Health for the PMHNP?
A) Advanced psychopharmacological interventions for complex mental health
conditions
B) The neuroscientific foundations for psychiatric disorders and mental
health problems across the lifespan
C) Therapeutic communication techniques for individuals with severe mental
illness
D) Administrative and leadership strategies for psychiatric-mental health
nursing
Correct Answer: The neuroscientific foundations for psychiatric disorders and
mental health problems across the lifespan
Rationale: The UT Arlington catalog states that NURS 5410 "provides the
neuroscientific foundations for various psychiatric disorders and mental
health problems across the lifespan." This foundational knowledge is critical
for the Psychiatric Mental Health Nurse Practitioner (PMHNP) role.
2. Which course outcome for NURS 5410 involves differentiating normal from
abnormal signs and symptoms using evidence-based criteria?
A) Evaluate the neurobiology of various psychiatric disorders
B) Analyze the genetic and epigenetic factors relevant to psychiatric
disorders
C) Differentiate normal from abnormal signs and symptoms using DSM-5 and
other evidence-based criteria
D) Develop appropriate diagnoses that include environmental and contextual
factors
Correct Answer: Differentiate normal from abnormal signs and symptoms
using DSM-5 and other evidence-based criteria
,Rationale: Course Outcome #4 for NURS 5410 is to "Differentiate normal
from abnormal signs and symptoms patients with mental health problems
across the lifespan, using DSM-5 and other evidence-based criteria."
3. The primary structural and functional unit of the nervous system is the:
A) Glial cell
B) Neuron
C) Synapse
D) Neurotransmitter
Correct Answer: Neuron
Rationale: The neuron is the fundamental structural and functional unit of the
nervous system, responsible for receiving, processing, and transmitting
information through electrical and chemical signals.
4. A neuron receives signals from other neurons primarily through which
structure?
A) Axon
B) Dendrites
C) Soma
D) Axon terminal
Correct Answer: Dendrites
Rationale: Dendrites are the branched extensions of a neuron that receive
incoming signals (neurotransmitters) from other neurons and conduct them
toward the cell body (soma).
5. Which part of the neuron is responsible for transmitting impulses away
from the cell body to other neurons, muscles, or glands?
A) Dendrites
B) Soma
,C) Axon
D) Synaptic cleft
Correct Answer: Axon
Rationale: The axon is a long, slender projection of the neuron that conducts
electrical impulses (action potentials) away from the cell body toward the
axon terminals, where neurotransmitters are released.
6. The gap between two neurons where neurotransmitters are released and
received is known as the:
A) Node of Ranvier
B) Synaptic cleft
C) Myelin sheath
D) Axon hillock
Correct Answer: Synaptic cleft
Rationale: The synaptic cleft is the microscopic gap between the presynaptic
neuron (which releases neurotransmitters) and the postsynaptic neuron
(which receives them). Neurotransmitters diffuse across this space to
transmit signals.
7. Which type of glial cell is responsible for producing the myelin sheath in
the central nervous system?
A) Schwann cells
B) Astrocytes
C) Oligodendrocytes
D) Microglia
Correct Answer: Oligodendrocytes
Rationale: Oligodendrocytes are glial cells in the central nervous system
(CNS) that produce the myelin sheath, which insulates axons and speeds up
neural transmission. Schwann cells perform this function in the peripheral
nervous system.
, 8. A patient presents with symptoms of depression, including low mood,
anhedonia, and fatigue. Which neurotransmitter system is most commonly
implicated in the pathophysiology of major depressive disorder?
A) Dopamine
B) Serotonin
C) Glutamate
D) Gamma-aminobutyric acid (GABA)
Correct Answer: Serotonin
Rationale: The monoamine hypothesis of depression suggests that
deficiencies in serotonin, norepinephrine, and dopamine contribute to
depressive symptoms. Serotonin dysfunction is particularly associated with
mood regulation, sleep, appetite, and impulse control, making it a primary
target for many antidepressants (SSRIs).
9. Which neurotransmitter is the primary inhibitory neurotransmitter in the
central nervous system, and its dysfunction is implicated in anxiety
disorders?
A) Glutamate
B) Dopamine
C) Gamma-aminobutyric acid (GABA)
D) Norepinephrine
Correct Answer: Gamma-aminobutyric acid (GABA)
Rationale: GABA is the major inhibitory neurotransmitter in the brain. It
reduces neuronal excitability. Decreased GABA activity is associated with
anxiety disorders, and benzodiazepines enhance GABA's effects to produce
anxiolytic and sedative properties.
10. An increase in which neurotransmitter is most strongly associated with
the positive symptoms of schizophrenia, such as hallucinations and
delusions?
