Section 1: Pediatric History & Developmental Assessment (Q1-8)
Question 1
Mr. Smith brings his 4-year-old son James to the clinic. During the focused history, you
ask about James's developmental milestones. Which skill is most developmentally
appropriate for a 4-year-old child?
A. Riding a bicycle without training wheels
B. Hopping on one foot and catching a bounced ball
C. Tying shoelaces independently
D. Reading simple sentences aloud
Correct Answer: B
Rationale: Hopping on one foot and catching a bounced ball (B) are classic 4-year-old
gross motor milestones. Choice A is typically achieved around 5-6 years. Choice C
(tying shoelaces) is a 5-6 year fine motor skill. Choice D (reading) is a school-age skill
(6+ years). MN 553 Principle: 4-year-old gross motor milestones include hopping on one
foot, catching ball, alternating feet on stairs, standing on one foot 2-5 seconds. Fine
motor: draws circle/square, uses scissors, buttons/unbuttons. Language: 4-5 word
sentences, tells stories, knows colors, understands same/different. Social: cooperative
play, shares, separates easily, imaginary play.
,Question 2
During the developmental history, Mr. Smith reports that James speaks in 2-word
phrases and points to objects he wants rather than naming them. Based on this
information, which conclusion is most accurate?
A. This is age-appropriate language development for a 4-year-old
B. This represents a significant language delay requiring further evaluation and early
intervention referral
C. This is a normal variation and will likely resolve without intervention
D. This indicates James is simply shy and needs more socialization
Correct Answer: B
Rationale: A 4-year-old should speak in 4-5 word sentences, tell stories, and know colors
(B). Two-word phrases and pointing are 18-24 month milestones, representing a
significant expressive language delay requiring referral for speech-language evaluation
and early intervention services. Choice A is incorrect—this is not age-appropriate.
Choice C is dangerous—delays do not typically resolve without intervention and early
treatment is most effective. Choice D minimizes a significant developmental concern.
MN 553 Principle: Language delay red flags at 4 years: <3 word sentences, unclear
speech to strangers, inability to follow 3-step commands, no pretend play. Early
intervention (Birth to 3) or school-based services (3+) should be initiated promptly.
Parental concern always warrants evaluation.
Question 3
You review James's immunization record. According to the CDC 2026 immunization
schedule, which vaccines are routinely due at the 4-year well-child visit?
A. Hepatitis B, Rotavirus, and Hib
,B. DTaP, IPV, MMR, and Varicella
C. Tdap, HPV, and Meningococcal
D. Hepatitis A, Pneumococcal, and Influenza
Correct Answer: B
Rationale: The CDC schedule recommends DTaP (5th dose), IPV (4th dose), MMR (2nd
dose), and Varicella (2nd dose) at 4-6 years of age (B). Choice A lists infant vaccines
(Hep B birth, Rotavirus 2/4 months, Hib 2/4/6/12-15 months). Choice C lists adolescent
vaccines (Tdap at 11-12 years, HPV at 9-12 years, Meningococcal at 11-12 years).
Choice D includes Hepatitis A (12-23 months, 2nd dose 6 months later), Pneumococcal
(infant series + booster at 12-15 months), and Influenza (annual, starting at 6 months).
MN 553 Principle: 4-6 year vaccines: DTaP #5, IPV #4, MMR #2, Varicella #2. If any
doses missed, catch-up schedule applies. Administer today if due and child is not
acutely ill with moderate/severe illness (mild illness like URI with low-grade fever is not
a contraindication).
Question 4
Mr. Smith reports that James was born at 38 weeks gestation via spontaneous vaginal
delivery, birth weight 3.2 kg (7 lbs 1 oz), with no NICU stay or complications. Which
element of the birth history is most relevant when assessing current health concerns?
A. The exact time of day James was born
B. The gestational age and absence of perinatal complications
C. The name of the delivering physician
D. The hospital where James was born
Correct Answer: B
Rationale: Gestational age (term vs. preterm) and perinatal complications (B) are critical
for understanding baseline health, risk factors, and developmental expectations.
, Preterm birth (<37 weeks) increases risks for respiratory, neurodevelopmental, and
growth issues. Choice A is irrelevant to current health assessment. Choice C is not
clinically relevant. Choice D may be relevant for record retrieval but not for clinical
decision-making. MN 553 Principle: Birth history components: gestational age, birth
weight, mode of delivery, Apgar scores, complications (respiratory distress, jaundice,
hypoglycemia, sepsis), NICU stay, maternal infections (GBS, chorioamnionitis),
substance exposure. Term, uncomplicated birth with normal growth trajectory supports
current well-child status.
Question 5
James attends preschool three days per week. Which social history element is most
important to assess given his current presentation of fever, cough, and ear tugging?
A. James's favorite toys at preschool
B. Recent illness exposures at preschool and daycare attendance patterns
C. The name of James's preschool teacher
D. James's preferred snack foods at preschool
Correct Answer: B
Rationale: Preschool and daycare attendance (B) significantly increases exposure to
respiratory pathogens, otitis media, and other communicable illnesses. Understanding
illness patterns in classmates and recent exposures helps narrow differential diagnosis
and guide infection control counseling. Choice A is not clinically relevant. Choice C is
irrelevant to diagnosis. Choice D may relate to nutrition but not to acute infectious
illness. MN 553 Principle: Daycare/preschool attendance = risk factor for URI, otitis
media, gastroenteritis, strep pharyngitis, HFMD. Assess: recent sick contacts, outbreak
notifications, travel, exposure to secondhand smoke (increases URI/otitis risk), pet
exposure (zoonotic infections), recent antibiotics (resistant organisms).
