PSYCHIATRY BOARD CERTIFICATION EXAM COMPREHENSIVE
PRACTICE QUESTIONS AND VERIFIED ANSWERS WITH
DETAILED RATIONALES
1. Which neurotransmitter is primarily associated with the
pathophysiology of schizophrenia?
A) Serotonin
B) Dopamine
C) Norepinephrine
D) GABA
Answer: B
Rationale: The dopamine hypothesis of schizophrenia posits that
positive symptoms are related to excessive dopaminergic activity in the
mesolimbic pathway, while negative symptoms are related to decreased
dopaminergic activity in the mesocortical pathway.
2. A patient presents with anhedonia, insomnia, feelings of
worthlessness, and difficulty concentrating for the past three weeks.
What is the most likely diagnosis?
A) Generalized Anxiety Disorder
B) Major Depressive Disorder
C) Bipolar I Disorder
D) Persistent Depressive Disorder
Answer: B
Rationale: The presence of five or more depressive symptoms (including
anhedonia and mood disturbance) for at least two weeks meets the
DSM-5-TR criteria for Major Depressive Disorder.
,3. Which class of medications is considered first-line for the treatment
of Generalized Anxiety Disorder?
A) Benzodiazepines
B) SSRIs
C) Tricyclic antidepressants
D) Antipsychotics
Answer: B
Rationale: SSRIs and SNRIs are first-line treatments for GAD due to their
favorable side effect profile and efficacy in treating chronic anxiety.
4. A patient taking clozapine presents with fever, tachycardia, and
muscle rigidity. What is the priority nursing intervention?
A) Administer the next dose of clozapine
B) Hold the medication and notify the provider immediately
C) Encourage fluids and monitor vital signs
D) Administer a PRN benzodiazepine
Answer: B
Rationale: These symptoms suggest Neuroleptic Malignant Syndrome
(NMS), a life-threatening emergency requiring immediate
discontinuation of the antipsychotic and medical intervention.
5. Which defense mechanism is characterized by attributing one's own
unacceptable thoughts or feelings to another person?
A) Projection
B) Displacement
C) Rationalization
D) Sublimation
Answer: A
Rationale: Projection involves falsely attributing one's own threatening
impulses, motives, or feelings onto another person.
,6. What is the primary mechanism of action of lithium?
A) Blocking dopamine D2 receptors
B) Inhibiting serotonin reuptake
C) Modulating second messenger systems (e.g., IP3, cAMP)
D) Enhancing GABA activity
Answer: C
Rationale: Lithium works by modulating intracellular second messenger
systems, specifically inhibiting inositol monophosphatase, which affects
neurotransmitter release.
7. A patient with bipolar disorder is experiencing a manic episode.
Which symptom is most characteristic?
A) Decreased need for sleep
B) Anhedonia
C) Psychomotor retardation
D) Auditory hallucinations
Answer: A
Rationale: A decreased need for sleep (feeling rested after only 3 hours)
is a hallmark symptom of a manic episode in bipolar disorder.
8. Which therapeutic communication technique involves restating the
patient's message in different words to confirm understanding?
A) Clarification
B) Reflection
C) Paraphrasing
D) Summarizing
Answer: C
Rationale: Paraphrasing involves restating the patient's message in
different words to ensure the nurse understands the patient's intended
meaning.
, 9. A patient is diagnosed with PTSD. Which symptom cluster includes
avoidance of stimuli associated with the trauma?
A) Intrusion symptoms
B) Avoidance symptoms
C) Negative alterations in cognitions and mood
D) Alterations in arousal and reactivity
Answer: B
Rationale: Avoidance symptoms in PTSD include avoiding distressing
memories, thoughts, feelings, or external reminders of the traumatic
event.
10. Which medication is FDA-approved for the treatment of Attention-
Deficit/Hyperactivity Disorder (ADHD) and is a central nervous system
stimulant?
A) Atomoxetine
B) Methylphenidate
C) Guanfacine
D) Clonidine
Answer: B
Rationale: Methylphenidate is a CNS stimulant that increases dopamine
and norepinephrine in the synaptic cleft, effectively treating ADHD
symptoms.
11. What is the most common side effect of Selective Serotonin
Reuptake Inhibitors (SSRIs) during the initial weeks of treatment?
A) Weight gain
B) Sexual dysfunction
C) Gastrointestinal upset
D) Sedation
Answer: C
