Section 1: Subjective Data Collection - Pediatric History (Q1-15)
Q1. A 4-month-old infant is brought to the clinic by his mother, who states, "He's
been pulling at his right ear and crying for the past two days." Using the OLDCARTS
framework for pediatric presentations, which element of the history is most critical to
document first to guide urgency of evaluation?
A. The infant's FLACC pain score during the ear tug examination
B. The exact timing of onset and any associated fever >38°C
C. The mother's description of the character of the crying (high-pitched vs. normal)
D. The infant's feeding pattern over the past 24 hours
B. The exact timing of onset and any associated fever >38°C [CORRECT]
Rationale: In infants <3 months, fever ≥38°C (100.4°F) is a medical emergency
requiring immediate sepsis workup per AAP guidelines; at 4 months, fever still
significantly elevates concern for serious bacterial infection (SBI) and influences
whether outpatient management vs. hospitalization is appropriate. While FLACC
scoring (A) and feeding patterns (D) are important, fever status determines urgency.
The character of crying (C) is less immediately actionable than fever data. Bright
Futures/AAP recommends fever documentation as a priority vital sign in all ill-
appearing infants.
Correct Answer: B
Q2. A 2-year-old girl presents with her father, who reports she has had "watery
diarrhea six times today and won't eat anything." Using the pediatric-specific review
of systems, which stool characteristic documentation is most essential for this acute
presentation?
,A. The Bristol Stool Scale type (applicable only to toilet-trained children)
B. Frequency, consistency, presence of blood/mucus, and pain with passage
C. Toilet training status and any recent encopresis history
D. The child's favorite foods prior to symptom onset
B. Frequency, consistency, presence of blood/mucus, and pain with passage
[CORRECT]
Rationale: For acute diarrhea in a toddler, documenting frequency, consistency
(watery vs. formed), and presence of blood or mucus is critical to differentiate viral
gastroenteritis (most common, watery, no blood) from bacterial enteritis
(mucoid/bloody, painful) or intussusception (currant jelly stool). The Bristol Stool
Scale (A) is designed for toilet-trained children and not practical for a 2-year-old in
diapers. Toilet training status (C) is irrelevant to acute infectious diarrhea. Food
preferences (D) do not guide differential diagnosis in this acute setting.
Correct Answer: B
Q3. During a well-child visit for a 6-month-old breastfed infant, the mother asks
about introducing solid foods. Which documentation in the feeding history is most
important to capture before providing anticipatory guidance?
A. Current breastfeeding frequency, duration per feed, and any latch concerns
B. The brand of infant formula the mother plans to use as backup
C. The infant's preference for bottle vs. breast based on prior exposure
D. The mother's weight gain during pregnancy
A. Current breastfeeding frequency, duration per feed, and any latch concerns
[CORRECT]
Rationale: Before recommending solid food introduction at 6 months (per AAP Bright
Futures), the NP must assess breastfeeding adequacy—frequency, duration, and latch
quality—to ensure sufficient milk transfer and weight gain. Formula brand (B) is
irrelevant if exclusively breastfeeding. Bottle preference (C) does not inform readiness
for solids. Maternal pregnancy weight gain (D) has no bearing on infant feeding
readiness.
,Correct Answer: A
Q4. A 9-month-old boy is seen for a routine well-child visit. His mother reports he
sleeps in her bed "because it's easier for nighttime breastfeeding." Which element of
the sleep history requires the most urgent safety counseling and documentation?
A. Total hours of sleep per 24 hours (currently 13 hours including naps)
B. Co-sleeping/bed-sharing arrangement and parental substance use
C. Bedtime resistance and night waking frequency
D. Snoring and observed apnea episodes during sleep
B. Co-sleeping/bed-sharing arrangement and parental substance use [CORRECT]
Rationale: Bed-sharing increases SIDS risk 5-10 fold, especially with parental
smoking, alcohol, or drug use, soft bedding, or parental obesity per AAP safe sleep
guidelines. This requires immediate safety counseling and documentation of risk
factors. While total sleep hours (A) and bedtime resistance (C) are relevant, they are
not safety emergencies. Snoring/apnea (D) is important but less immediately life-
threatening than unsafe sleep environment.
Correct Answer: B
Q5. During a 15-month well-child visit, the mother of a toddler expresses concern
that her child "only says 'mama' and 'dada' but nothing else." Which developmental
milestone documentation is most critical to guide referral decisions?
A. Whether the child uses 2-word phrases consistently
B. Whether the child follows one-step commands without gestures
C. Whether the child has achieved independent walking
D. Whether the child demonstrates parallel play with other children
B. Whether the child follows one-step commands without gestures [CORRECT]
Rationale: At 15 months, expected expressive language includes 3-5 words; however,
receptive language (following one-step commands without gestures) is equally
, critical. A child with normal receptive language but limited expressive vocabulary
may be a "late talker" requiring monitoring, while deficits in both domains suggest
broader developmental delay requiring immediate early intervention referral per CDC
Learn the Signs Act Early 2026. Two-word phrases (A) are expected by 24 months,
not 15 months. Walking (C) and parallel play (D) are separate developmental
domains.
Correct Answer: B
Q6. A 3-week-old newborn is seen for a weight check. Which birth history element is
most essential to document to explain current poor weight gain?
A. Gestational age at delivery, birth weight, and any NICU admission
B. Maternal preference for vaginal vs. cesarean delivery
C. The father's occupation during the pregnancy
D. The newborn's Apgar scores at 1 and 5 minutes
A. Gestational age at delivery, birth weight, and any NICU admission [CORRECT]
Rationale: Gestational age (preterm vs. term), birth weight (small for gestational age
vs. appropriate), and NICU course (feeding difficulties, respiratory support affecting
oral feeding) directly impact expected weight gain trajectories and feeding
recommendations. Delivery method preference (B) has no clinical relevance to weight
gain. Paternal occupation (C) is irrelevant. Apgar scores (D) reflect immediate
transition but do not predict ongoing growth patterns.
Correct Answer: A
Q7. An 8-year-old with asthma presents for a follow-up visit. Which past medical
history documentation is most critical for assessing current control?
A. Frequency of exacerbations in the past 12 months, identified triggers, and
controller medication adherence
B. The age at which the child first learned to ride a bicycle
