Evidence-Based Mental Health Practice Review
Question 1: Which neurotransmitter system is primarily targeted by selective serotonin
reuptake inhibitors (SSRIs) in the treatment of major depressive disorder?
A. Dopamine
B. Norepinephrine
C. Serotonin
D. Acetylcholine
CORRECT ANSWER: C. Serotonin
Rationale: SSRIs function by inhibiting the reuptake of serotonin into the presynaptic neuron,
thereby increasing the availability of serotonin in the synaptic cleft to improve mood and
alleviate depressive symptoms.
Question 2: A patient presenting with acute mania, grandiosity, and decreased need for sleep
is most likely suffering from which condition?
A. Major Depressive Disorder
B. Bipolar I Disorder
C. Generalized Anxiety Disorder
D. Schizoid Personality Disorder
CORRECT ANSWER: B. Bipolar I Disorder
Rationale: Bipolar I Disorder is characterized by at least one manic episode, which includes
symptoms such as grandiosity, decreased need for sleep, and heightened activity levels, often
without a requirement for a depressive episode for diagnosis.
Question 3: When prescribing clozapine, what is the mandatory monitoring requirement due
to the risk of agranulocytosis?
A. Monthly liver function tests
B. Weekly absolute neutrophil count (ANC) initially
C. Daily electrocardiograms
D. Quarterly thyroid panels
CORRECT ANSWER: B. Weekly absolute neutrophil count (ANC) initially
Rationale: Clozapine carries a black box warning for agranulocytosis; therefore, strict
monitoring of the absolute neutrophil count (ANC) is required weekly for the first six months,
then bi-weekly, and finally monthly if stable.
Question 4: Which psychotherapeutic approach is considered the gold standard for treating
Obsessive-Compulsive Disorder (OCD)?
A. Psychodynamic Therapy
B. Exposure and Response Prevention (ERP)
C. Humanistic Therapy
D. Gestalt Therapy
CORRECT ANSWER: B. Exposure and Response Prevention (ERP)
,Rationale: Exposure and Response Prevention (ERP), a form of Cognitive Behavioral Therapy
(CBT), is the most evidence-based treatment for OCD, involving gradual exposure to fears while
preventing the compulsive ritual.
Question 5: A patient on lithium therapy reports nausea, tremors, and confusion. What is the
priority nursing action?
A. Administer an antiemetic
B. Check serum lithium levels immediately
C. Increase the lithium dosage
D. Encourage fluid intake only
CORRECT ANSWER: B. Check serum lithium levels immediately
Rationale: These symptoms indicate potential lithium toxicity. The priority is to assess serum
lithium levels to determine toxicity severity and guide immediate intervention, such as holding
the dose or hydration.
Question 6: Which DSM-5-TR criterion is essential for diagnosing Post-Traumatic Stress
Disorder (PTSD)?
A. Presence of manic episodes
B. Exposure to actual or threatened death, serious injury, or sexual violence
C. Chronic worry for at least six months
D. Hallucinations unrelated to trauma
CORRECT ANSWER: B. Exposure to actual or threatened death, serious injury, or sexual
violence
Rationale: Criterion A for PTSD requires direct exposure, witnessing, or learning about a
traumatic event involving actual or threatened death, serious injury, or sexual violence.
Question 7: What is the primary mechanism of action of bupropion?
A. Serotonin reuptake inhibition
B. Dopamine and norepinephrine reuptake inhibition
C. GABA receptor agonism
D. Glutamate antagonism
CORRECT ANSWER: B. Dopamine and norepinephrine reuptake inhibition
Rationale: Bupropion is an atypical antidepressant that acts as a norepinephrine-dopamine
reuptake inhibitor (NDRI), distinguishing it from SSRIs and making it useful for patients with
sexual side effects or smoking cessation needs.
Question 8: In the context of advanced practice nursing, what does "duty to warn" refer to?
A. Informing family of a diagnosis
B. Notifying authorities if a patient threatens specific harm to an identifiable victim
C. Warning patients about medication side effects
D. Reporting substance use to employers
CORRECT ANSWER: B. Notifying authorities if a patient threatens specific harm to an
identifiable victim
Rationale: Based on the Tarasoff ruling, mental health professionals have a legal and ethical
obligation to breach confidentiality if a patient poses a serious threat of violence to an
identifiable third party.
,Question 9: Which medication is FDA-approved specifically for the treatment of Alcohol Use
Disorder to reduce cravings?
A. Disulfiram
B. Naltrexone
C. Fluoxetine
D. Lorazepam
CORRECT ANSWER: B. Naltrexone
Rationale: Naltrexone is an opioid antagonist that reduces the rewarding effects of alcohol and
decreases cravings, making it a first-line pharmacotherapy for Alcohol Use Disorder.
Question 10: A patient exhibits flattened affect, avolition, and alogia. These are classified as
what type of symptoms in schizophrenia?
A. Positive symptoms
B. Negative symptoms
C. Cognitive symptoms
D. Affective symptoms
CORRECT ANSWER: B. Negative symptoms
Rationale: Negative symptoms in schizophrenia refer to the absence or reduction of normal
behaviors, such as emotional expression (flattened affect), motivation (avolition), and speech
(alogia).
Question 11: What is the recommended first-line pharmacological treatment for Generalized
Anxiety Disorder (GAD)?
A. Benzodiazepines
B. SSRIs or SNRIs
C. Antipsychotics
D. Beta-blockers
CORRECT ANSWER: B. SSRIs or SNRIs
Rationale: Selective Serotonin Reuptake Inhibitors (SSRIs) and Serotonin-Norepinephrine
Reuptake Inhibitors (SNRIs) are considered first-line treatments for GAD due to their efficacy
and favorable safety profile compared to benzodiazepines.
Question 12: Which assessment tool is commonly used to screen for depression in primary
care settings?
A. MMSE
B. PHQ-9
C. Y-BOCS
D. PANSS
CORRECT ANSWER: B. PHQ-9
Rationale: The Patient Health Questionnaire-9 (PHQ-9) is a validated, widely used screening
tool for detecting and measuring the severity of depression in clinical settings.
Question 13: A patient taking an MAOI must avoid foods high in which substance to prevent a
hypertensive crisis?
A. Sodium
B. Tyramine
, C. Potassium
D. Calcium
CORRECT ANSWER: B. Tyramine
Rationale: Monoamine Oxidase Inhibitors (MAOIs) inhibit the breakdown of tyramine; ingestion
of tyramine-rich foods (e.g., aged cheeses, cured meats) can lead to excessive norepinephrine
release and a dangerous hypertensive crisis.
Question 14: What is the hallmark feature of Dissociative Identity Disorder (DID)?
A. Persistent memory loss of personal information
B. Presence of two or more distinct personality states
C. Fixed false beliefs
D. Auditory hallucinations
CORRECT ANSWER: B. Presence of two or more distinct personality states
Rationale: DID is characterized by the presence of two or more distinct personality states or
identities that recurrently take control of the individual's behavior, accompanied by memory
gaps.
Question 15: Which side effect is most commonly associated with second-generation
antipsychotics like olanzapine?
A. Agranulocytosis
B. Metabolic syndrome (weight gain, dyslipidemia, hyperglycemia)
C. Neuroleptic Malignant Syndrome
D. Stevens-Johnson Syndrome
CORRECT ANSWER: B. Metabolic syndrome (weight gain, dyslipidemia, hyperglycemia)
Rationale: Second-generation antipsychotics, particularly olanzapine and clozapine, are strongly
associated with metabolic side effects, requiring regular monitoring of weight, glucose, and
lipids.
Question 16: In motivational interviewing, what does the acronym OARS stand for?
A. Observe, Assess, Refer, Support
B. Open-ended questions, Affirmations, Reflections, Summaries
C. Offer, Ask, Review, Solve
D. Orient, Analyze, Respond, Summarize
CORRECT ANSWER: B. Open-ended questions, Affirmations, Reflections, Summaries
Rationale: OARS represents the core communication skills in Motivational Interviewing used to
engage patients, build rapport, and evoke change talk.
Question 17: A patient presents with rapid cycling bipolar disorder. Which mood stabilizer is
often preferred?
A. Lithium
B. Valproate (Depakote)
C. Sertraline
D. Alprazolam
CORRECT ANSWER: B. Valproate (Depakote)
Rationale: Valproate is often considered more effective than lithium for patients with rapid-
cycling bipolar disorder, defined as four or more mood episodes within a year.
