APEA PMHNP-PSYCHIATRIC-MENTAL
HEALTH NURSE PRACTITIONER EXAM
COMPLETE QUESTIONS AND VERIFIED
ANSWERS
Question 1: According to current psychopharmacology principles tested on the
APEA PMHNP examination, which of the following best explains the primary
mechanism of action of selective serotonin reuptake inhibitors (SSRIs) and
why this class is considered first-line for major depressive disorder in most
adult patients?
A. They block dopamine D2 receptors in the mesolimbic pathway, reducing positive
symptoms of psychosis
B. They inhibit the reuptake of serotonin at the synaptic cleft, increasing
serotonergic neurotransmission and producing gradual improvement in mood,
anxiety, and related symptoms
C. They enhance GABA activity through binding at the benzodiazepine receptor site
D. They irreversibly inhibit monoamine oxidase, leading to increased levels of
multiple monoamines
CORRECT ANSWER: B. They inhibit the reuptake of serotonin at the synaptic
cleft, increasing serotonergic neurotransmission and producing gradual
improvement in mood, anxiety, and related symptoms
Rationale: SSRIs selectively block the serotonin transporter (SERT), raising synaptic
serotonin concentrations. This action, combined with downstream receptor
adaptations, underlies their efficacy in major depressive disorder, anxiety disorders,
and related conditions, making them first-line due to favorable safety and
tolerability profiles compared with older agents.
Question 2: When evaluating a patient for bipolar I disorder according to
DSM-5-TR criteria emphasized in APEA PMHNP preparation materials, which
of the following clinical features is required to establish the diagnosis?
A. At least one hypomanic episode lasting a minimum of four consecutive days
without hospitalization
B. At least one manic episode that is distinct, lasts at least one week (or any
duration if hospitalization is required), and causes marked impairment or psychosis
C. Recurrent depressive episodes without any history of elevated mood
D. Chronic low-grade mood elevation lasting at least two years
CORRECT ANSWER: B. At least one manic episode that is distinct, lasts at least
one week (or any duration if hospitalization is required), and causes marked
impairment or psychosis
Rationale: DSM-5-TR requires a lifetime history of at least one fully syndromal
Page 1 of 66
,manic episode for the diagnosis of bipolar I disorder. Hypomanic episodes alone
define bipolar II disorder, and depressive episodes alone do not meet criteria for
bipolar I.
Question 3: In the management of acute agitation in a patient with
schizophrenia in an emergency setting, which intramuscular medication
combination is most consistent with evidence-based practice guidelines
reviewed in APEA PMHNP exam content?
A. Oral lorazepam alone without antipsychotic coverage
B. Intramuscular haloperidol combined with intramuscular lorazepam, with careful
monitoring for extrapyramidal symptoms and respiratory depression
C. High-dose oral olanzapine without regard to QTc
D. Intravenous diazepam as monotherapy
CORRECT ANSWER: B. Intramuscular haloperidol combined with intramuscular
lorazepam, with careful monitoring for extrapyramidal symptoms and
respiratory depression
Rationale: The combination of a first-generation antipsychotic and a
benzodiazepine is a well-established approach for rapid tranquilization of acute
agitation. Monitoring for EPS, QT prolongation, and additive CNS depression is
essential for safe use.
Question 4: Which of the following statements most accurately describes the
black-box warning associated with all antidepressant medications in children,
adolescents, and young adults up to age 24, as tested on the APEA PMHNP
examination?
A. Antidepressants are completely contraindicated under age 25
B. Antidepressants may increase the risk of suicidal thinking and behavior; close
monitoring for clinical worsening, suicidality, and unusual behavioral changes is
required, especially during the initial months of treatment or at dose changes
C. Antidepressants have no effect on suicidality in any age group
D. The warning applies only to tricyclic antidepressants
CORRECT ANSWER: B. Antidepressants may increase the risk of suicidal
thinking and behavior; close monitoring for clinical worsening, suicidality, and
unusual behavioral changes is required, especially during the initial months of
treatment or at dose changes
Rationale: The FDA black-box warning highlights an increased risk of suicidal
ideation and behavior in younger patients treated with antidepressants. Clinicians
must educate patients and families and institute appropriate monitoring while
recognizing that untreated depression itself carries substantial suicide risk.
Question 5: A 34-year-old patient with major depressive disorder has failed
two adequate trials of SSRIs. According to measurement-based care and
treatment algorithms emphasized in APEA PMHNP preparation, which next-
step strategy is most appropriate?
A. Immediately initiate electroconvulsive therapy without further medication trials
B. Switch to a different antidepressant class or add an evidence-based
Page 2 of 66
,augmentation agent such as an atypical antipsychotic, lithium, or another
antidepressant while continuing systematic symptom monitoring
C. Discontinue all medication and rely solely on psychotherapy
D. Increase the current SSRI to three times the maximum recommended dose
CORRECT ANSWER: B. Switch to a different antidepressant class or add an
evidence-based augmentation agent such as an atypical antipsychotic, lithium,
or another antidepressant while continuing systematic symptom monitoring
Rationale: After two failed adequate antidepressant trials, guidelines support
switching to an agent from a different class or using augmentation strategies with
documented efficacy. Measurement-based care (e.g., PHQ-9 tracking) guides further
adjustments.
Question 6: Which of the following laboratory parameters must be monitored
regularly in a patient receiving long-term lithium therapy for bipolar disorder,
consistent with APEA PMHNP standards of care?
A. Only complete blood count every five years
B. Serum lithium level, renal function (BUN/creatinine), thyroid function (TSH), and
serum calcium at baseline and at regular intervals thereafter
C. Liver function tests exclusively
D. Fasting lipid panel only
CORRECT ANSWER: B. Serum lithium level, renal function (BUN/creatinine),
thyroid function (TSH), and serum calcium at baseline and at regular intervals
thereafter
Rationale: Lithium has a narrow therapeutic index and can cause renal impairment,
hypothyroidism, and hyperparathyroidism. Regular monitoring of serum levels and
target-organ function is mandatory for safe long-term use.
Question 7: When distinguishing between delirium and dementia in an older
adult presenting with acute confusion, which clinical feature is most
supportive of a diagnosis of delirium according to DSM-5-TR and APEA
PMHNP content?
A. Gradual onset over months to years with progressive memory decline
B. Acute onset over hours to days, fluctuating course, and disturbance of attention
and awareness that represents a change from baseline
C. Presence of visual hallucinations only in the evening
D. Intact attention with isolated short-term memory loss
CORRECT ANSWER: B. Acute onset over hours to days, fluctuating course, and
disturbance of attention and awareness that represents a change from baseline
Rationale: Delirium is characterized by acute onset, fluctuating levels of
consciousness and attention, and a clear precipitant. Dementia typically has an
insidious onset and progressive course without the marked attentional fluctuations
of delirium.
Question 8: A patient with schizophrenia has developed significant metabolic
syndrome while taking olanzapine. Which alternative second-generation
antipsychotic is generally associated with a lower risk of weight gain and
metabolic adverse effects and is therefore often preferred in this scenario?
Page 3 of 66
, A. Clozapine
B. Quetiapine
C. Aripiprazole or ziprasidone (or lurasidone)
D. Olanzapine at a higher dose
CORRECT ANSWER: C. Aripiprazole or ziprasidone (or lurasidone)
Rationale: Among second-generation antipsychotics, aripiprazole, ziprasidone, and
lurasidone are associated with relatively lower risks of weight gain and metabolic
disturbance compared with olanzapine, clozapine, and quetiapine, making them
preferable choices when metabolic concerns predominate.
Question 9: According to APEA PMHNP examination content on therapeutic
communication, which response by the nurse practitioner best demonstrates
the technique of reflection when a patient states, “I feel like a complete failure
because I lost my job”?
A. “You shouldn’t feel that way; lots of people lose jobs.”
B. “You’re feeling like a complete failure because of the job loss.”
C. “Let’s talk about something more positive.”
D. “Have you updated your résumé yet?”
CORRECT ANSWER: B. “You’re feeling like a complete failure because of the
job loss.”
Rationale: Reflection restates the patient’s emotional content, conveying empathy
and encouraging further exploration without judgment or premature problem-
solving.
Question 10: Which of the following is the most appropriate initial
pharmacologic treatment for a patient with moderate-to-severe generalized
anxiety disorder who has no history of substance use disorder, according to
current guidelines referenced in APEA PMHNP materials?
A. Long-term daily alprazolam as monotherapy
B. An SSRI or SNRI as first-line pharmacotherapy, with consideration of short-term
benzodiazepine use only if necessary for severe acute symptoms
C. High-dose quetiapine as initial therapy
D. Immediate initiation of phenelzine
CORRECT ANSWER: B. An SSRI or SNRI as first-line pharmacotherapy, with
consideration of short-term benzodiazepine use only if necessary for severe
acute symptoms
Rationale: SSRIs and SNRIs have the strongest evidence for long-term efficacy and
safety in generalized anxiety disorder. Benzodiazepines may be used short-term for
acute relief but carry risks of dependence and cognitive impairment with prolonged
use.
Question 11: In the assessment of a patient presenting with first-episode
psychosis, which laboratory and diagnostic studies are considered essential
components of the medical work-up before attributing symptoms solely to a
primary psychiatric disorder?
A. Only a urine drug screen
