A 5-year-old boy is referred for "uncontrollable movements." His mother describes repetitive, rhythmic hand-flapping and head-nodding that occur when he is excited or bored. These movements can be stopped if he is called by name or distracted by a toy. He has no history of vocalizations and meets all developmental milestones for social interaction and language. What is the most likely diagnosis?
Tourette Syndrome
Stereotypic Movement Disorder
Autism Spectrum Disorder
Motor Tic Disorder
Explanation: Stereotypic Movement Disorder is characterized by repetitive, seemingly driven, and
nonfunctional motor behavior (e.g., hand flapping, body rocking). Unlike tics, stereotypes are rhythmic,
have an earlier onset (usually before age 3), and can be easily suppressed by distraction or sensory input.
Since the child has no social-communication deficits (ruling out ASD) and the movements are rhythmic
and distractible (ruling out tics), Stereotypic Movement Disorder is the correct diagnosis.
Parents of a 9-year-old with oppositional behaviors describe the child as “exactly like his uncle who had similar problems.” What comprehensive history step is indicated?
Defer history and proceed directly to medication evaluation.
Obtain only current behavioral rating scales from school.
Elicit a comprehensive developmental, behavioral, environmental, and health history including the
caregivers’ perception and comparison to family members.
Limit questioning to the child’s diet and sleep only.
Explanation: A comprehensive developmental, behavioral, environmental, and health history that includes
caregivers’ perception and family comparisons provides context on heritability, environmental modifiers,
and family explanatory models. This supports accurate differential diagnosis and family-centered
intervention planning.
A 20-month-old child scores 9 on the M-CHAT-R (high-risk range). What action maximizes early identification while minimizing unnecessary evaluations?
Rely on clinical observation alone without standardized screening
Repeat the M-CHAT-R in 1 month before any action
Administer full follow-up interview despite high score and delay referral if negative
Bypass follow-up and refer directly for ASD diagnostic evaluation and early intervention
Explanation: The correct approach involves immediate referral for diagnostic evaluation and early
intervention services for children scoring 8-20 on the M-CHAT-R, as this high-risk threshold indicates
substantial concern for autism spectrum disorder even before follow-up, though the follow-up can still
provide useful behavioral detail while expediting services to improve developmental outcomes.
A 13-year-old girl is brought in because she refuses to go to school. She claims she has constant "brain fog" and "dizziness" that makes it impossible to concentrate. Despite normal neurological and cardiac evaluations, she insists she is too ill to function. She spends most of her day in bed. Her mother, who has a history of chronic fatigue syndrome, is very supportive of her daughter's "sick role." This dynamic is a significant factor in:
Illness Anxiety Disorder
Factitious Disorder by Proxy
Somatic Symptom Disorder
Separation Anxiety Disorder
Explanation: In Somatic Symptom Disorder, environmental factors and family dynamics often play a role
in the maintenance of symptoms. The reinforcement of the "sick role" by a parent (especially one who has
their own chronic illness) can inadvertently validate the child's impairment and discourage a return to
normal functioning. The focus here is on the child's distressing symptoms and the resulting functional
impairment, which aligns with SSD.
A 12‑year‑old with oppositional defiant disorder (ODD) and school refusal has been offered a 12‑week parent‑management training in behavior (PMT) program, but the waitlist is 10 weeks. The family reports escalating conflicts at home and the child is already at risk of academic failure. Which intervention is most appropriate to initiate immediately while awaiting PMT?
Provide brief behavioral activation schedule and daily reward plan for school attendance
Refer urgently for inpatient psychiatric hospitalization
Prescribe sertraline 25 mg daily for school refusal anxiety
Start atomoxetine 25 mg daily for possible comorbid ADHD
Explanation: For school refusal and ODD‑like behaviors, evidence supports early behavioral interventions
(e.g., daily routines, graded exposure, and contingent positive reinforcement) as first‑line while awaiting
longer‑term parent‑training or therapy. Pharmacologic treatment is indicated only if a clear comorbid
disorder (e.g., ADHD, depression, or anxiety) limits response to behavioral strategies. Inpatient
hospitalization is reserved for safety or severe functional impairment.
What is the role of the Pediatric Mental Health Specialist when counseling families about managing electronics for an ADHD patient?
Total prohibition of all electronics in the home
Teach parents to use electronics as a reward, not a right
Provide strategies to use screens as a "babysitting" tool
Ensure the child has no access to the internet at school
Explanation: Viewing electronics as a privilege—a reward earned for completing responsibilities—rather
than an inherent right helps parents establish healthy boundaries. This structure teaches the child time
management and delayed gratification, which are critical skills that are often underdeveloped in children
with ADHD.
A 17-year-old with depression and suicidal ideation (no plan) on fluoxetine requires close monitoring. What schedule and collaboration per GLAD-PC?
Daily phone checks
Weekly follow-up (in-person or phone) for first month, then biweekly; involve school counselor for
safety planning
Refer all to ER
Monthly visits sufficient
Explanation: GLAD-PC guidelines stress prompt and frequent monitoring (weekly initially) after
antidepressant initiation or dose change in adolescents with depression/suicidality. Collaborate with schools
for safety and academic supports. Safety planning with family and resources is key. This prevents
escalation while managing in primary/specialty collaborative model.
3-year-old regression (3→0 words), head banging post-febrile illness. Normal MRI/metabolic. What urgent consultation?
Infectious disease encephalitis PCR
Epilepsy center continuous EEG
Geneticist exome sequencing
Child protective services environmental
Explanation: Post-infectious regression mandates seizure exclusion via prolonged EEG given behavioral
epileptiform mimicry, Pediatric Mental Health Specialist emergent referral protocol preceding genetic
workup. CPS neglect chronic; genetics static; ID acute CSF absent fever.
A mother of a 4-year-old with severe ADHD symptoms is being pressured by the preschool to start the child on medication or he will be expelled. The Pediatric Mental Health Specialist believes the child should first try evidence-based behavioral parent training (BPT). How should the Pediatric Mental Health Specialist advocate for this family?
Write a letter stating the child has a disability and cannot be disciplined
Call the school and explain that BPT is the first-line treatment for this age group per the AAP
Agree with the school and prescribe the medication to prevent expulsion
Tell the mother to find a different preschool that is more "understanding"
Explanation: Advocacy often involves educating other systems (like schools) on clinical standards of care.
For preschoolers, the American Academy of Pediatrics (AAP) explicitly recommends Behavioral Parent
Training/Behavioral Classroom Management as the first-line treatment before medication. By advocating
for this sequence, the Pediatric Mental Health Specialist protects the child from premature
pharmacotherapy while providing the school with a constructive path forward.
A 5-year-old with iron deficiency anemia (ferritin 8 ng/mL) in food-insecure household relies on processed
foods. What risk reduction education?
Vitamin C avoidance
Iron infusions
Oral iron supplements alone
Link food insecurity to anemia and provide WIC enrollment with heme-iron food demos
Explanation: Linking food insecurity as a social determinant to poor heme-iron intake, with WIC
enrollment and cooking demos, educates on nutritional disparities and facilitates absorption via practical,
culturally tailored strategies reversing anemia effectively.
A 3-year-old toddler shows delays in gross and fine motor skills, language acquisition, and social engagement compared to peers on Ages & Stages Questionnaire (ASQ) screening, with no regression but failure to meet multiple developmental milestones. Comprehensive evaluation rules out sensory deficits, autism, and genetic syndromes. What is the appropriate classification and management priority?
Global developmental delay; refer to early intervention services for multidisciplinary therapies
Communication disorder; focus solely on speech therapy
Intellectual disability; initiate special education placement immediately
Specific learning disorder; provide classroom accommodations only
Explanation: Global developmental delay is diagnosed in children under 5 years when there is significant
delay in ≥2 developmental domains (motor, speech, cognitive, social) based on standardized testing,
prompting urgent referral to early intervention programs offering physical, occupational, speech, and
developmental therapies. This maximizes neuroplasticity and prevents secondary complications.
Intellectual disability requires deficits in both intellectual and adaptive functioning with onset in
developmental period but is typically confirmed after age 5 with IQ testing. Specific learning disorders
manifest later in academic settings.
A 15‑year‑old boy with moderate‑to‑severe bipolar I disorder in mania has a YMRS score of 32, pressured speech, and decreased need for sleep. He has no prior psychiatric medication exposure. Which intervention best reflects first‑line pharmacologic treatment in a pediatric bipolar manic episode?
Start lithium 300 mg twice daily and arrange weekly lab monitoring of lithium level, renal function, and thyroid.
Initiate aripiprazole 2 mg daily and titrate to 10 mg daily over 2 weeks.
Prescribe a benzodiazepine and delay mood‑stabilizer initiation until a child psychiatrist evaluates him.
Begin valproate 500 mg twice daily and monitor for hepatotoxicity and weight gain.
Explanation: For adolescents with bipolar I mania, lithium remains a first‑line mood stabilizer with strong
evidence for efficacy and, when carefully monitored, acceptable safety. Starting at a moderate dose (e.g.,
300 mg twice daily) and titrating based on serum level, renal function, and thyroid status is
guideline‑concordant. Aripiprazole and valproate are valid alternatives but do not replace lithium as the
primary first‑line agent in many protocols. Benzodiazepines alone are not sufficient for mood stabilization
in mania and should be adjunctive at most.
During ASQ-3 administration to a 36-month-old, communication 20th percentile, personal-social 10th percentile, with 4/15 red flags. Problem-solving fine motor normal. What Pediatric Mental Health Specialist-guided tool modification or adjunct is indicated?
Add ESPO (Early Screening of Psychotic Disorders)
ASQ:SE-2 for socioemotional specificity
Repeat ASQ-3 in 2 months
Bayley-4 cognitive composite
Explanation: ASQ:SE-2 complements ASQ-3 developmental delays with targeted
socioemotional/behavioral items, standard Pediatric Mental Health Specialist practice for low personal-
social domains to differentiate global vs. relational delays. ESPO irrelevant; Bayley diagnostic not
screening; repeat delays intervention.
A 9-year-old boy with visual impairment from retinopathy of prematurity and hearing loss exhibits tactile defensiveness, difficulty with noisy environments, and repetitive rocking behaviors that interfere with learning. Developmental testing confirms global delays without meeting full autism criteria.
Refer to occupational and sensory integration therapy while coordinating with vision/hearing specialists for environmental modifications
Initiate low-dose antipsychotic for stereotypic movements
Diagnose sensory processing disorder as primary and defer further evaluation
Recommend strict behavioral extinction techniques at school
Explanation: Neurosensory impairments such as combined vision and hearing loss in children often lead to
compensatory repetitive behaviors and sensory modulation difficulties. Multidisciplinary intervention
including occupational therapy for sensory integration, alongside adaptations for visual and auditory
access, improves functional participation and reduces maladaptive patterns. This approach targets
underlying processing challenges rather than suppressing behaviors in isolation.
A 6-year-old boy recently diagnosed with autism spectrum disorder level 1 (ADOS-2 module 2 score in mild range, strong verbal skills but social challenges) and his parents disagree on priorities: the child enjoys his train collection and resists change, the father wants social skills training, and the mother seeks better routine tolerance. The provider uses a structured family meeting to synthesize preferences and functional assessments. What is the most effective collaborative strategy for establishing treatment goals?
Recommend intensive applied behavior analysis immediately and set goals post-referral
Facilitate consensus on hybrid goals incorporating the child's interest in trains as a motivator for social
routines and tolerance-building, with measurable weekly targets tracked by all
Prioritize social skills training as the primary goal because it addresses core deficits identified on ADOS-
2
Create separate goals for each family member without integration
Explanation: Collaborative goal-setting for neurodevelopmental disorders requires incorporating the child's
strengths and preferences (e.g., special interests) as motivators, balancing caregiver priorities, and creating
integrated, measurable objectives across domains. Using the child's interest facilitates buy-in, supports
environmental adaptations, and allows team tracking, consistent with strengths-based, family-centered
approaches in primary care mental health management.
A 16-year-old female is preoccupied with a small, barely visible mole on her forearm, insisting it makes her look "monstrous" and "diseased." She has visited three different dermatologists to have it surgically removed, but all have refused, stating it is benign and cosmetically insignificant. She now refuses to wear short sleeves and has stopped attending gym class. Which feature is essential to distinguish this from typical adolescent vanity?
Request for a medical procedure to alter the appearance
The location of the perceived defect on an extremity
Presence of significant functional impairment in daily life
Occurrence of the preoccupation in a female patient
Explanation: A key diagnostic criterion for Body Dysmorphic Disorder (BDD) that separates it from
normal appearance concerns or vanity is that the preoccupation must cause clinically significant distress or
impairment in social, occupational, or other important areas of functioning. Missing school and avoiding
social situations due to the perceived defect are clear indicators of functional impairment.
5-year-old with ADHD symptoms (Conners T-score 75) in food-insecure single-parent household. SNAP benefits lapsed. Caregiver perceives symptoms as "sugar crashes from cheap food." What evaluation incorporates social determinants?
Trial stimulant medication
Comprehensive history integrating food insecurity patterns, sleep arrangements in shared bedroom, and
caregiver mental health screening with PSC-17
Eliminate artificial colors from diet
Order sleep study
Explanation: Integrating detailed food insecurity timelines showing SNAP gaps correlating with symptom
exacerbation, shared bedroom sleep disruptions fragmenting attention regulation, and caregiver depression
screening via PSC-17 reveals how social determinants amplify neurodevelopmental vulnerabilities beyond
primary ADHD pathology. This contextualizes behavioral presentations, prioritizes resource navigation for
nutrition stability and private sleep space, and differentiates environmental contributors requiring systemic
intervention from medication-responsive core symptoms.
A 30-month-old PEDS parent concern questionnaire positive development concerns (language, motor), positive relationship concerns (separation anxiety, peer play). Follow-up pathway B score elevated. Normal hearing screen. ASQ-3 borderline communication.
Speech therapy early intervention only
Normal developmental variation
Psychosocial risk comprehensive evaluation
Isolated language delay monitoring
Explanation: PEDS pathway B positive concerns across development and relationships identifies at-risk status requiring early intervention referral, as validated screener sensitivity 74%-92% captures children needing services regardless of medical etiology.
Which of the following findings on a sleep study (polysomnography) would be most diagnostic of Narcolepsy in an adolescent complaining of excessive daytime sleepiness?
Total sleep time of 10 hours with a sleep efficiency of 98 percent
Increased percentage of Stage N3 sleep during the first half of the night
A sleep-onset REM period (SOREMP) occurring within 15 minutes of sleep onset
An apnea-hypopnea index (AHI) of 15 events per hour of sleep
Explanation: Narcolepsy is characterized by the brain's inability to regulate sleep-wake cycles, leading to
REM sleep intruding into wakefulness or occurring immediately at the start of sleep. A Sleep-Onset REM
Period (SOREMP) is a hallmark finding on the Multiple Sleep Latency Test (MSLT) or
polysomnography, where the patient enters REM sleep much faster than the typical 90-minute cycle.
A 7-year-old child presents with a BMI of 28 kg/m2. The parents report the child frequently eats large amounts of food in secret, accompanied by feelings of guilt. What assessment tool is most appropriate to help clarify this behavior?
The PHQ-9.
The Eating Disorder Examination Questionnaire (EDE-Q).
The Vanderbilt ADHD Rating Scale.
The Children’s Yale-Brown Obsessive Compulsive Scale (CY-BOCS).
Explanation: Given the clinical presentation of binge-eating symptoms and significant weight gain, an eating
disorder screening tool like the EDE-Q is appropriate to assess for potential Binge Eating Disorder (BED).
This demonstrates the integration of medical (BMI) and mental health indicators into the diagnostic
decision-making process.
A 17-year-old male is being treated for a severe Tic Disorder. He has failed to respond to alpha-2 agonists (Guanfacine) and behavioral therapy. You are considering a "typical" antipsychotic medication that is
FDA-approved for Tourette Syndrome. Which of the following medications fits this description but requires close monitoring for extrapyramidal side effects and QTc prolongation?
Haloperidol
Ziprasidone
Quetiapine
Risperidone
Explanation: Haloperidol and Pimozide are "typical" (first-generation) antipsychotics that are FDA-
approved for the treatment of Tourette Syndrome. While highly effective at suppressing tics, they are
associated with significant side effects including dystonia, akathisia, and tardive dyskinesia. Haloperidol
also carries a risk of QTc prolongation, requiring baseline and periodic EKGs. They are generally reserved
for severe cases that have failed safer first-line treatments like Guanfacine or CBIT.
A 7-year-old child presents with frequent tantrums, poor school focus, and sleep difficulties. The caregiver describes the behaviors as “out of control” and notes frustration with prior advice. The family recently moved to a neighborhood with limited resources. What is the most appropriate initial step for the Pediatric Mental Health Specialist?
Refer directly for neurodevelopmental testing before gathering any history.
Obtain a comprehensive developmental, behavioral, environmental, and health history while exploring
the caregiver’s perception of the concern, its onset, triggers, and family impact.
Conduct a focused review of systems and order laboratory tests to rule out medical causes first.
Administer standardized behavioral rating scales immediately without further context.
Explanation: Obtaining a comprehensive developmental, behavioral, environmental, and health history,
including the caregiver’s perception of the concern, establishes the foundation for accurate Pediatric
Mental Health Specialist evaluation. This step captures symptom timeline, contextual triggers such as
recent relocation, environmental stressors, and the family’s explanatory model, enabling targeted
differential diagnosis, rapport building, and culturally sensitive planning while avoiding premature or
incomplete assessments.
A 13-year-old boy with bipolar disorder and history of seizures requires mood stabilization. He is currently seizure-free off antiepileptics but has had two prior episodes. Which medication offers dual benefit for mood and potential seizure threshold while requiring specific monitoring?
Lamotrigine with slow titration to minimize rash risk
Carbamazepine with CBC and level monitoring
Lithium with serum level, renal, and thyroid monitoring
Valproate with weight, liver, and hematologic monitoring
Explanation: The correct approach involves valproate for its established role in pediatric bipolar mania and
aggression, plus its antiepileptic properties that may provide dual benefit in patients with seizure history.
Monitoring includes weight, liver function tests, platelets, ammonia, and pancreatic enzymes due to risks
of hepatotoxicity, thrombocytopenia, and pancreatitis. Lithium requires renal and thyroid surveillance but
lacks direct antiseizure activity. Lamotrigine is useful for bipolar maintenance but requires very slow
titration to avoid serious rash. Carbamazepine has more drug interactions and hematologic risks.
A 15-year-old with anxiety reveals during a confidential visit that they are questioning their sexual orientation and fears parental reaction based on family religious beliefs. No safety concerns exist. Which action best upholds confidentiality regulations?
Maintain privacy regarding sexual orientation disclosure, offer resources tailored to LGBTQ+ youth with cultural and faith considerations, and support gradual family communication if desired by the patient
Maintain privacy regarding sexual orientation disclosure, offer resources tailored to LGBTQ+ youth with cultural and faith considerations, and support gradual family communication if desired by the patient
Share the information with parents to facilitate family support and acceptance
Share the information with parents to facilitate family support and acceptance
Explanation: Sexual orientation and related mental health discussions often fall under sensitive services
where minor consent and privacy protections apply under HIPAA and ethical codes. Providers facilitate
support without breaching trust, incorporating intersectional factors like religion and culture.
SCARED total 25 in 13-year-old male: social phobia 10, panic 3, separation 4, GAD 5, school 3. Reports lunchroom avoidance, test tremor. Duration 6 months. GPA decline.
Social anxiety disorder primary diagnosis
Specific phobia school situations
Subclinical anxiety watchful waiting
Generalized anxiety disorder treatment
Explanation: SCARED social phobia subscale ≥8 with functional impairment (lunchroom avoidance, GPA
decline) establishes DSM-5 social anxiety disorder diagnosis, as validated cutoff predicts 79% sensitivity
requiring exposure-based CBT targeting performance fears.
