Q1 Question 1 of 70
A 34-year-old patient diagnosed with major depressive disorder asks the nurse why medication alone
does not make the symptoms go away. The nurse explains that the biologic basis of depression
involves neurotransmitter dysfunction in specific brain pathways. Which neurotransmitter imbalance is
most commonly associated with the development of major depressive disorder?
A. Decreased serotonin, norepinephrine, and dopamine activity in limbic and cortical pathways
B. Decreased gamma-aminobutyric acid leading to excessive neuronal excitation
C. Increased acetylcholine activity causing overstimulation of muscarinic receptors
D. Elevated glutamate levels producing excitotoxicity in the hippocampus
Correct Answer: A
Rationale:
The monoamine theory of depression holds that deficient activity of serotonin, norepinephrine, and dopamine in
key brain regions such as the prefrontal cortex and limbic system underlies the core symptoms of depression
including depressed mood, anhedonia, and cognitive dysfunction. Decreased GABA (choice A) is more
associated with anxiety disorders, and elevated glutamate (choice D) with excitotoxic damage rather than
primary depression.
Q2 Question 2 of 70
A nursing student is learning about the stress response and asks the instructor which hormone is
primarily responsible for the fight-or-flight reaction during acute psychological stress. The instructor
explains the hypothalamic-pituitary-adrenal axis activation. Which hormone release is the final step in
this cascade?
A. Aldosterone released from the adrenal cortex in response to angiotensin
B. Cortisol released from the adrenal cortex in response to ACTH
C. Epinephrine released from the adrenal medulla in response to sympathetic stimulation
D. Thyroxine released from the thyroid gland in response to TSH
Correct Answer: B
Rationale:
The HPA axis response to stress proceeds from hypothalamic CRH to pituitary ACTH to adrenal cortical cortisol
release, making cortisol the final hormonal product of this cascade; chronic cortisol elevation is linked to
hippocampal damage and depression. Epinephrine (choice C) is released via the sympathetic nervous system,
not the HPA axis, and represents a separate but parallel stress response.
,Q3 Question 3 of 70
A 45-year-old patient with schizophrenia has been compliant with risperidone therapy for six months.
The psychiatric nurse reviews the dopamine hypothesis of schizophrenia with the nursing team.
According to this theory, which brain region is associated with the positive symptoms of
schizophrenia?
A. The mesocortical pathway where deficient dopamine activity produces negative symptoms
B. The nigrostriatal pathway where dopamine blockade produces extrapyramidal side effects
C. The mesolimbic pathway where excessive dopamine activity produces hallucinations and
delusions
D. The tuberoinfundibular pathway where dopamine blockade elevates prolactin levels
Correct Answer: C
Rationale:
The dopamine hypothesis posits that hyperdopaminergic activity in the mesolimbic pathway produces the
positive symptoms of schizophrenia (hallucinations, delusions, thought disorder), while hypodopaminergic
activity in the mesocortical pathway (choice B) produces negative symptoms. Choices C and D describe
pathways responsible for medication side effects rather than symptom generation.
Q4 Question 4 of 70
A mental health nurse is caring for a patient who experienced severe childhood trauma and now
exhibits chronic hyperarousal and flashbacks. The nurse understands that the patient's amygdala is
likely hyperactive. Which function of the amygdala best explains this clinical presentation?
A. Processing of explicit declarative memories for factual recall
B. Coordination of motor planning and executive function
C. Regulation of sleep-wake cycles and circadian rhythm
D. Detection of threat and activation of the fear response
Correct Answer: D
Rationale:
The amygdala is the brain's primary threat-detection center that rapidly evaluates sensory input for danger and
initiates the fear response, which explains why trauma survivors with amygdalar hyperactivity experience chronic
hyperarousal and intrusive flashbacks. Explicit memory processing (choice A) is a hippocampal function, while
motor planning (choice B) involves the prefrontal cortex and basal ganglia.

, Q5 Question 5 of 70
A 28-year-old patient with bipolar disorder is in an acute manic episode. The psychiatric nurse
explains to the family that mania is associated with dysregulation of specific neurotransmitters. Which
neurotransmitter change is most linked to manic symptoms?
A. Increased norepinephrine and dopamine activity in cortical and limbic regions
B. Excessive serotonin activity in the raphe nuclei
C. Deficient GABA activity in the cerebellum
D. Decreased acetylcholine activity in the basal forebrain
Correct Answer: A
Rationale:
Manic episodes are associated with excessive norepinephrine and dopamine activity in cortical and limbic brain
regions, producing euphoria, grandiosity, psychomotor agitation, and decreased need for sleep; mood stabilizers
like lithium help dampen this overactivity. Excessive serotonin (choice A) is not a recognized mechanism of
mania, and the cerebellar and basal forebrain regions (choices C and D) are not the primary sites of manic
pathology.
Q6 Question 6 of 70
A mental health nurse is educating a patient about how selective serotonin reuptake inhibitors work.
The patient asks how the medication will change brain chemistry over several weeks. Which
mechanism best explains the delayed therapeutic effect of SSRIs?
A. Immediate blockade of serotonin reuptake producing rapid symptom relief
B. Downregulation of postsynaptic serotonin receptors and neuroadaptive changes over time
C. Permanent destruction of the serotonin transporter protein
D. Conversion of serotonin to norepinephrine through enzymatic action
Correct Answer: B
Rationale:
Although SSRIs block serotonin reuptake within hours, the clinical antidepressant effect takes weeks because
therapeutic response depends on downstream neuroadaptive changes including postsynaptic receptor
downregulation, increased BDNF expression, and hippocampal neurogenesis. Immediate reuptake blockade
(choice A) does occur but does not produce the therapeutic effect; the delay is due to the neuroadaptation, not
immediate pharmacologic action.
