knowledge of psychiatric mental health nursing modalities, treatment approaches,
and evidence-based interventions for the NSG 526 course, with detailed EXPERT
RATIONALE for each answer to deepen understanding and support exam
preparation.
• Study this material by reviewing each question carefully, attempting to answer
before reading the EXPERT RATIONALE, and focusing on areas where you struggle
to achieve mastery of clinical modalities and their appropriate applications in
psychiatric care.
QUESTION 1
What is the primary mechanism of action for selective serotonin reuptake
inhibitors (SSRIs) in treating depression?
A) Increasing dopamine levels in the nucleus accumbens
B) Blocking the reuptake of serotonin at the synaptic cleft, increasing serotonin
availability
C) Inhibiting monoamine oxidase to prevent neurotransmitter breakdown
D) Enhancing GABA transmission to promote sedation and anxiety relief
E) Directly blocking histamine receptors to improve mood
,CORRECT ANSWER: B) Blocking the reuptake of serotonin at the synaptic cleft,
increasing serotonin availability ✓
EXPERT RATIONALE: SSRIs work by selectively inhibiting the reuptake of serotonin
at the presynaptic terminal, thereby increasing the concentration of serotonin
available in the synaptic cleft. This increased serotonin availability is believed to
improve mood regulation, reduce anxiety, and alleviate depressive symptoms.
SSRIs are first-line agents for major depressive disorder and anxiety disorders due
to their efficacy and tolerability profile.
QUESTION 2
A 45-year-old patient with bipolar I disorder is started on lithium carbonate.
Which parameter must be monitored most closely during the initial
treatment phase?
A) Liver function tests weekly
B) Serum lithium levels, with therapeutic range of 0.6-1.2 mEq/L
C) Complete blood count monthly
D) Thyroid function annually only
E) Blood glucose levels before each dose
CORRECT ANSWER: B) Serum lithium levels, with therapeutic range of 0.6-1.2
mEq/L ✓
EXPERT RATIONALE: Lithium has a narrow therapeutic window (0.6-1.2 mEq/L),
requiring frequent monitoring during initiation. Serum levels should be checked 5
days after initiation, then regularly (often weekly until stable, then monthly). The
therapeutic margin between an effective dose and a toxic dose is small. Lithium
toxicity can cause serious complications including tremor, confusion, cardiac
arrhythmias, and renal damage. Regular monitoring of renal function and thyroid
function is important but serum levels are the most critical parameter during initial
treatment.
,QUESTION 3
Which psychotherapy modality is most effective for treating specific phobias
through systematic desensitization and exposure techniques?
A) Psychoanalysis
B) Dialectical behavior therapy (DBT)
C) Cognitive behavioral therapy (CBT)
D) Interpersonal therapy (IPT)
E) Existential therapy
CORRECT ANSWER: C) Cognitive behavioral therapy (CBT) ✓
EXPERT RATIONALE: CBT, particularly exposure-based therapy and systematic
desensitization, is the gold standard treatment for specific phobias. This modality
works by gradually exposing the patient to the feared stimulus while teaching
coping strategies and cognitive restructuring. Research demonstrates superior
efficacy for phobias compared to other psychotherapies. CBT addresses both the
cognitive component (fear thoughts) and the behavioral component (avoidance).
QUESTION 4
A patient with treatment-resistant depression has failed trials of three
different antidepressants. Which somatic therapy should be considered as a
next step?
A) Transcranial magnetic stimulation (TMS) or electroconvulsive therapy (ECT)
B) Increased dosage of the current SSRI
C) Addition of a benzodiazepine for anxiety management
D) Herbal supplementation with St. John's Wort
E) Immediate hospitalization for observation only
CORRECT ANSWER: A) Transcranial magnetic stimulation (TMS) or
electroconvulsive therapy (ECT) ✓
, EXPERT RATIONALE: For treatment-resistant depression (failure of adequate trials
of 2-3 antidepressants), somatic therapies like TMS and ECT are evidence-based
options. ECT has approximately 60-70% response rate for severe, treatment-
resistant depression. TMS is non-invasive with fewer cognitive side effects. Both are
supported by clinical guidelines when pharmacotherapy has been inadequate.
Increasing current medication or adding benzodiazepines alone does not address
treatment resistance.
QUESTION 5
What is the primary goal of dialectical behavior therapy (DBT) when used in
the treatment of borderline personality disorder?
A) To achieve complete personality restructuring within 6 months
B) To reduce dysfunctional behaviors while accepting the patient and promoting
change through validation and problem-solving
C) To eliminate all emotional dysregulation through medication adjustment
D) To provide permanent cure through intensive psychoanalysis
E) To focus solely on unconscious conflicts from childhood
CORRECT ANSWER: B) To reduce dysfunctional behaviors while accepting the
patient and promoting change through validation and problem-solving ✓
EXPERT RATIONALE: DBT, developed by Marsha Linehan specifically for borderline
personality disorder, balances acceptance and change strategies. The dialectic
combines validation (acceptance) with problem-solving and behavioral change
techniques. Key DBT modes include individual therapy, skills training groups
(mindfulness, distress tolerance, emotion regulation, interpersonal effectiveness),
phone coaching, and therapist consultation teams. The goal is to reduce self-harm,
suicidal behaviors, and other dysfunctional patterns while improving quality of life.
