HEALTH NURSING (PMHNP)
Comprehensive Board Certification Examination & Clinical Case-Based
Assessment
Featuring 200 Rigorous Clinical Questions with Detailed Rationales
Core Clinical Stem for Primary Case Study:
A PMHNP is conducting a psychiatric evaluation on an 8-year-old child referred for severe
motor and vocal tics persisting for over 14 months, accompanied by prominent intrusive thoughts
and repetitive hand-washing rituals. This foundational clinical presentation frames the pediatric
psychopathology, differential diagnosis, neurobiology, and evidence-based treatment planning
explored throughout this 200-question professional examination.
SECTION I: ADVANCED PSYCHIATRIC ASSESSMENT &
DIFFERENTIAL DIAGNOSIS (Questions 1-50)
1. Based on the clinical presentation of an 8-year-old child with
severe motor and vocal tics persisting for over 14 months,
accompanied by prominent intrusive thoughts and repetitive hand-
washing rituals, what is the most likely primary or comorbid
diagnosis pair?
A. Generalized Anxiety Disorder and Specific Phobia
B. Tourette's Disorder and Obsessive-Compulsive Disorder (OCD)
C. Chronic Motor Tic Disorder and Separation Anxiety Disorder
D. Persistent Depressive Disorder and Autism Spectrum Disorder
Correct Answer: B. Tourette's Disorder and Obsessive-
Compulsive Disorder (OCD)
Rationale: Rationale: Tourette's Disorder requires the presence of
multiple motor tics and at least one vocal tic present for more than 1
year. The co-occurrence of intrusive thoughts and repetitive
compulsions (hand-washing rituals) strongly fulfills criteria for
, comorbid Obsessive-Compulsive Disorder (OCD), which occurs in
up to 50% of individuals with Tourette's Disorder.
2. Which neurocircuitry abnormality is most consistently implicated
in the pathophysiology connecting Tourette's Disorder and
Obsessive-Compulsive Disorder?
A. Mesolimbic dopaminergic pathway hyperactivity
B. Cortico-striato-thalamo-cortical (CSTC) circuit dysfunction
C. Direct pathway degeneration within the cerebellar vermis
D. Hyperactivity of the noradrenergic locus coeruleus projections
Correct Answer: B. Cortico-striato-thalamo-cortical (CSTC)
circuit dysfunction
Rationale: Rationale: Dysfunction within the cortico-striato-thalamo-
cortical (CSTC) loops—specifically involving the orbitofrontal
cortex, anterior cingulate cortex, and striatum—is central to the
pathophysiology of both OCD and tic disorders, disrupting gating
mechanisms and leading to repetitive behaviors and involuntary
movements.
3. When initiating pharmacotherapy for severe, impairing motor
and vocal tics in an 8-year-old child unresponsive to behavioral
interventions, which FDA-approved medication class is considered
first-line due to a favorable side effect profile?
A. Typical antipsychotics (e.g., Haloperidol)
B. Alpha-2 adrenergic agonists (e.g., Clonidine or Guanfacine)
C. Selective serotonin reuptake inhibitors (e.g., Sertraline)
D. Stimulants (e.g., Methylphenidate)
Correct Answer: B. Alpha-2 adrenergic agonists (e.g., Clonidine
or Guanfacine)
Rationale: Rationale: Alpha-2 adrenergic agonists (clonidine and
, guanfacine) are generally considered first-line pharmacological
agents for tic disorders due to lower risks of extrapyramidal
symptoms and tardive dyskinesia compared to antipsychotics. They
are also beneficial if comorbid ADHD or anxiety is present.
4. A parent reports that the 8-year-old child's onset of tics and OCD
symptoms occurred abruptly, virtually overnight, following a recent
streptococcal pharyngitis infection, accompanied by severe
emotional lability and urinary urgency. Which diagnostic entity
should the PMHNP consider?
A. Pediatric Acute-onset Neuropsychiatric Syndrome (PANS)
B. Pediatric Autoimmune Neuropsychiatric Disorders Associated
with Streptococcal Infections (PANDAS)
C. Sydenham Chorea without psychiatric features
D. Acute Disseminated Encephalomyelitis (ADEM)
Correct Answer: B. Pediatric Autoimmune Neuropsychiatric
Disorders Associated with Streptococcal Infections (PANDAS)
Rationale: Rationale: PANDAS is a subset of PANS specifically
defined by the abrupt onset of OCD and/or tic symptoms following a
group A beta-hemolytic streptococcal (GABHS) infection. PANS is a
broader category encompassing acute-onset OCD/tics triggered by
various infectious, metabolic, or environmental triggers.
5. Which evidence-based psychotherapeutic modality is established
as the first-line non-pharmacological treatment for tic disorders in
children?
A. Play Therapy
B. Comprehensive Behavioral Intervention for Tics (CBIT)
C. Eye Movement Desensitization and Reprocessing (EMDR)
D. Dialectical Behavior Therapy for Children (DBT-C)
, Correct Answer: B. Comprehensive Behavioral Intervention for
Tics (CBIT)
Rationale: Rationale: Comprehensive Behavioral Intervention for
Tics (CBIT), which includes habit reversal training (HRT) and
functional intervention, is the gold-standard first-line behavioral
therapy for tic disorders, helping patients identify premonitory urges
and employ competing responses.
6. For the management of comorbid OCD symptoms in this
pediatric patient, what is the gold-standard psychotherapeutic
intervention?
A. Psychoanalytic psychotherapy focused on unconscious conflict
B. Cognitive Behavioral Therapy (CBT) with Exposure and Response
Prevention (ERP)
C. Supportive counseling and stress inoculation training
D. Systematic desensitization using relaxation techniques alone
Correct Answer: B. Cognitive Behavioral Therapy (CBT) with
Exposure and Response Prevention (ERP)
Rationale: Rationale: CBT incorporating Exposure and Response
Prevention (ERP) is the frontline, evidence-based psychotherapy for
pediatric OCD, systematically exposing the child to obsessions while
preventing engagement in compulsions.
7. If pharmacotherapy is required for pediatric OCD, which
medication category is FDA-approved and considered first-line?
A. Tricyclic antidepressants (e.g., Clomipramine)
B. Selective Serotonin Reuptake Inhibitors (SSRIs, e.g., Fluoxetine,
Sertraline)
C. Monoamine Oxidase Inhibitors (e.g., Tranylcypromine)
D. Serotonin-Norepinephrine Reuptake Inhibitors (e.g., Venlafaxine)
