This examination is designed to evaluate the comprehensive knowledge and applied critical-thinking
skills of psychiatric-mental health nurse practitioner candidates preparing for the APEA PMHNP
certification examination. The assessment focuses on integrating foundational psychiatric theory with
real-world clinical scenarios, emphasizing diagnostic reasoning, pharmacotherapeutic decision-making,
and regulatory compliance. Through rigorous multiple-choice questions, candidates demonstrate
mastery of complex psychopathological processes, evidence-based interventions, and therapeutic
communication. The exam aims to ensure readiness for autonomous practice by testing the ability to
analyze, synthesize, and apply core concepts to diverse and challenging clinical situations encountered
across the lifespan in psychiatric care settings.
SECTION ONE: QUESTIONS 1–250
1. A 28-year-old patient presents with a two-week history of depressed mood, anhedonia, insomnia,
and feelings of worthlessness. Which of the following is the most appropriate initial screening tool for
major depressive disorder?
,A. PHQ-9
B. GAD-7
C. MMSE
D. CAGE
A. PHQ-9
RATIONALE: The PHQ-9 (Patient Health Questionnaire-9) is a validated, self-administered screening
tool specifically designed to assess the severity of depression based on the nine DSM-5 criteria for major
depressive disorder. It is widely used in primary care and psychiatric settings. The GAD-7 screens for
generalized anxiety disorder. The MMSE assesses cognitive function. The CAGE screens for alcohol use
disorders.
2. A patient with bipolar I disorder is currently experiencing a manic episode. Which of the following
medications is considered first-line for acute mania?
A. Fluoxetine
B. Lithium
C. Sertraline
D. Buspirone
B. Lithium
RATIONALE: Lithium is a mood stabilizer and is considered first-line therapy for acute mania in
bipolar I disorder. It is effective at controlling manic symptoms and preventing relapse. Fluoxetine,
sertraline, and buspirone are not indicated for acute mania; in fact, antidepressants can precipitate a
manic episode in patients with bipolar disorder.
3. A patient reports experiencing recurrent, unexpected panic attacks that have been occurring for the
past three months. The patient is now avoiding public places for fear of having another attack. Which
diagnosis is most likely?
A. Generalized anxiety disorder
B. Panic disorder with agoraphobia
C. Social anxiety disorder
D. Specific phobia
B. Panic disorder with agoraphobia
RATIONALE: Panic disorder is characterized by recurrent, unexpected panic attacks. When a patient
begins to avoid situations or places where escape might be difficult in the event of a panic attack, this
indicates agoraphobia. Generalized anxiety disorder involves chronic, pervasive worry. Social anxiety
disorder involves fear of social scrutiny. Specific phobia involves fear of a specific object or situation.
4. Which of the following is the primary mechanism of action of selective serotonin reuptake
inhibitors (SSRIs)?
A. Blockade of dopamine receptors
B. Inhibition of serotonin reuptake at the synaptic cleft
,C. Stimulation of GABA receptors
D. Inhibition of monoamine oxidase
B. Inhibition of serotonin reuptake at the synaptic cleft
RATIONALE: SSRIs work by blocking the serotonin transporter (SERT) at the presynaptic membrane,
preventing the reuptake of serotonin into the presynaptic neuron. This increases serotonin availability in
the synaptic cleft, enhancing serotonergic neurotransmission. Dopamine receptor blockade is the
mechanism of antipsychotics. GABA receptor stimulation is the mechanism of benzodiazepines. MAO
inhibition is the mechanism of MAOIs.
5. A 65-year-old patient presents with cognitive decline, disorientation, and visual hallucinations. The
symptoms began acutely over the past two days. Which of the following is the most likely diagnosis?
A. Alzheimer's disease
B. Delirium
C. Vascular dementia
D. Frontotemporal dementia
B. Delirium
RATIONALE: Delirium is characterized by an acute onset of confusion, disorientation, and perceptual
disturbances such as hallucinations. It is often caused by an underlying medical condition, medication
side effects, or substance withdrawal. Alzheimer's disease and other dementias typically have a gradual,
progressive onset. The acute onset within two days is the key distinguishing feature.
6. Which of the following medications is FDA-approved for the treatment of attention-
deficit/hyperactivity disorder (ADHD) in adults?
A. Fluoxetine
B. Methylphenidate
C. Sertraline
D. Clonazepam
B. Methylphenidate
RATIONALE: Methylphenidate is a stimulant medication FDA-approved for the treatment of ADHD in
both children and adults. It works by blocking the reuptake of dopamine and norepinephrine, increasing
their availability in the prefrontal cortex. Fluoxetine and sertraline are antidepressants. Clonazepam is a
benzodiazepine used for anxiety and seizure disorders.
7. A patient on an antipsychotic medication develops involuntary, repetitive movements of the
tongue, lips, and face. What is the most likely diagnosis?
A. Acute dystonia
B. Akathisia
C. Tardive dyskinesia
D. Parkinsonism
, C. Tardive dyskinesia
RATIONALE: Tardive dyskinesia (TD) is a late-onset extrapyramidal symptom characterized by
involuntary, repetitive movements, most commonly involving the tongue, lips, face, and jaw. It typically
develops after months or years of antipsychotic treatment. Acute dystonia involves sudden muscle
contractions. Akathisia is an inner restlessness. Parkinsonism involves tremor, rigidity, and bradykinesia.
8. Which of the following is the most appropriate first-line treatment for obsessive-compulsive
disorder (OCD)?
A. Clonazepam
B. An SSRI
C. Lithium
D. An antipsychotic
B. An SSRI
RATIONALE: SSRIs are considered first-line pharmacotherapy for OCD. They are effective at reducing
the frequency and intensity of obsessions and compulsions. Higher doses are often required than for
depression. Clonazepam may be used adjunctively but is not first-line. Lithium is for bipolar disorder.
Antipsychotics may be added for refractory OCD but are not first-line.
9. A patient with schizophrenia is started on clozapine. Which of the following laboratory values must
be monitored weekly?
A. Serum sodium
B. Absolute neutrophil count
C. Serum potassium
D. Liver function tests
B. Absolute neutrophil count
RATIONALE: Clozapine carries a risk of agranulocytosis, a potentially life-threatening drop in white
blood cell count. Patients must have their absolute neutrophil count (ANC) monitored weekly for the
first six months, then biweekly, then monthly. Other laboratory values may be monitored but the ANC is
the most critical for clozapine safety.
10. Which of the following is a characteristic symptom of post-traumatic stress disorder (PTSD)?
A. Persistent avoidance of trauma-related stimuli
B. Grandiosity and decreased need for sleep
C. Compulsive handwashing
D. Anhedonia and weight gain
A. Persistent avoidance of trauma-related stimuli
RATIONALE: PTSD is characterized by re-experiencing the trauma, avoidance of trauma-related
stimuli, negative alterations in cognitions and mood, and alterations in arousal and reactivity. Avoidance
