Growth & Development
A mother brings her 6-month-old infant for a well-child visit. Which developmental milestone is
most appropriate for this age?
A) Walking independently
B) Saying "mama" and "dada" specifically
C) Sitting without support [CORRECT]
D) Using a spoon independently
Rationale: By 6 months, infants typically sit without support. Walking occurs around 12 months,
specific "mama/dada" around 9-10 months, and spoon use around 12-15 months.
At what age should the MMR vaccine second dose typically be administered according to CDC
guidelines?
A) 12-15 months
B) 4-6 years [CORRECT]
C) 11-12 years
D) 2-3 years
Rationale: The first MMR dose is given at 12-15 months, with the second dose at 4-6 years
before school entry. This timing ensures optimal immune response.
A 22-year-old is starting a new job at a health center and has no record of MMR vaccination.
What is the appropriate recommendation?
A) No vaccine needed due to age
B) Single dose of MMR
C) Two doses of MMR at least 28 days apart [CORRECT]
D) Titer check only
Rationale: Adults without evidence of immunity should receive 2 doses of MMR at least 28 days
apart, especially those working in healthcare settings.
, hich of the following is the most reliable indicator of failure to thrive in an infant?
W
A) Single low weight measurement
B) Weight below 5th percentile on one occasion
C) Downward crossing of two major percentile lines on growth chart [CORRECT]
D) Parental concern about feeding
Rationale: Failure to thrive is defined as weight deceleration crossing two or more major
percentile lines, not a single low measurement.
A 9-month-old infant has not yet started crawling. The parents are concerned. What is the most
appropriate action?
A) Immediate referral to physical therapy
B) Reassurance that crawling is not a required milestone
C) Comprehensive developmental assessment [CORRECT]
D) Waiting until 12 months to reassess
Rationale: Crawling typically occurs by 9 months. Absence of this milestone warrants
assessment for motor delays, though some infants skip crawling.
Which anticipatory guidance is most appropriate for parents of a 12-month-old?
A) Begin whole milk and honey
B) Transition to forward-facing car seat
C) Expect 2-3 word phrases and walking independently [CORRECT]
D) Start potty training
Rationale: By 12 months, children typically walk independently and use 2-3 word phrases.
Honey should be avoided until after 12 months due to botulism risk.

A 4-year-old is brought to the clinic with concerns about obesity. The BMI percentile is 95th.
What is the first-line intervention?
A) Pharmacologic therapy
B) Bariatric surgery referral
C) Intensive lifestyle modification counseling [CORRECT]
D) Restrictive diet plan
Rationale: For pediatric obesity, the first-line approach is family-based lifestyle modification
focusing on healthy eating and increased physical activity.
Common Pediatric Conditions
A 3-year-old presents with ear pain, fever of 102°F, and a bulging, erythematous tympanic
membrane. The child has been symptomatic for 48 hours. What is the most appropriate
treatment?
A) Watchful waiting
B) Amoxicillin 80-90 mg/kg/day [CORRECT]
C) Azithromycin only
, ) Tympanostomy tubes
D
Rationale: This child meets criteria for acute otitis media (bulging TM, fever, pain <48 hours) and
should receive high-dose amoxicillin as first-line therapy.
A 5-year-old has acute otitis media with mild symptoms and no fever. The parents prefer to
avoid antibiotics. What is appropriate?
A) Immediate antibiotics regardless
B) Watchful waiting with safety net antibiotic prescription [CORRECT]
C) Tympanostomy tubes
D) Systemic steroids
Rationale: For mild AOM in children >2 years, observation for 48-72 hours with a safety net
prescription is appropriate per AAP guidelines.
A 7-year-old presents with sore throat, fever, and tender anterior cervical lymphadenopathy. No
cough is present. What is the next step?
A) Immediate antibiotic therapy
B) Rapid strep test or throat culture [CORRECT]
C) Monospot test
D) Reassurance only
Rationale: Centor criteria (fever, tonsillar exudates, tender nodes, no cough) suggest Group A
Strep. Testing before treatment prevents unnecessary antibiotics.
A 6-year-old with asthma uses albuterol more than twice weekly for symptoms. What is the
appropriate step in therapy?
A) Continue albuterol as needed
B) Add low-dose inhaled corticosteroid [CORRECT]
C) Start oral corticosteroids daily
D) Refer for pulmonary function testing only
Rationale: Using rescue inhaler >2 times/week indicates poor control. Step 2 therapy adds daily
low-dose ICS per NAEPP guidelines.

A) Daily bathing with lukewarm water
B) Fragrance-free moisturizers
C) Wool clothing [CORRECT]
D) Humidifier use in bedroom

A) Immediate toilet training reinforcement
B) Daily polyethylene glycol (PEG 3350) to achieve soft daily stools [CORRECT]
C) Stimulant laxatives only
D) Low-fiber diet
Rationale: Encopresis treatment requires disimpaction followed by maintenance with osmotic
laxatives like PEG to prevent re-accumulation.
A 3-month-old infant presents with fever of 101.5°F and no obvious source. What is the
appropriate management?
A) Observation at home
, ) Urinalysis, blood culture, and empiric antibiotics [CORRECT]
B
C) Chest X-ray only
D) Acetaminophen and recheck in 24 hours
Rationale: Febrile infants <3 months require full sepsis workup including UA, blood culture, and
empiric antibiotics due to risk of serious bacterial infection.
Adolescent Medicine
A 16-year-old female reports irregular periods occurring every 2-3 months. What is the most
appropriate initial evaluation?
A) Immediate hormonal contraception
B) Pregnancy test and thyroid function tests [CORRECT]
C) Pelvic ultrasound
D) Reassurance as normal variant
Rationale: Irregular menses in adolescents requires ruling out pregnancy, thyroid dysfunction,
PCOS, and hyperprolactinemia before treatment.

Isotretinoin is reserved for severe, scarring acne.
A 14-year-old is screened for substance use using the CRAFFT tool. Two or more positive
responses indicate:
A) Normal adolescent experimentation
B) Need for further assessment and possible intervention [CORRECT]
C) Immediate residential treatment
D) No concern warranted
Rationale: The CRAFFT tool identifies substance use risk. ≥2 positive responses indicate high
risk requiring further assessment and brief intervention.

A) Severe (10-15%)
B) Moderate (5-10%) [CORRECT]
C) Mild (3-5%)
D) No significant dehydration
Rationale: Moderate dehydration presents with dry mucous membranes, decreased skin turgor,

saturation of 88%. What is the priority intervention?
A) Oral corticosteroids
B) Continuous albuterol nebulization and supplemental oxygen [CORRECT]
