,Q1. A previously healthy child presents with acute-onset stridor, barking cough, and
low-grade fever. Which finding most reliably distinguishes croup from bacterial
tracheitis?
A. Presence of subglottic narrowing on neck radiograph
B. Toxic appearance and high fever
C. Response to nebulized epinephrine
D. Onset following a viral prodrome
Correct Answer: B. Toxic appearance and high fever
Rationale: Bacterial tracheitis is characterized by high fever, toxic appearance, and no
response to epinephrine, whereas croup typically presents with low-grade fever and
responds to nebulized epinephrine. Subglottic narrowing and viral prodrome are common
to both.
Why Wrong:
A - Subglottic narrowing is seen in both croup and tracheitis, so it does not reliably
distinguish them.
C - Response to epinephrine is typical of croup but not tracheitis, making it a
distinguishing feature, but the question asks for the most reliable finding; toxic
appearance is more definitive.
D - A viral prodrome can precede both conditions and is not distinguishing.
Reference: AAP Clinical Practice Guideline: Bronchiolitis and Croup (2024)
Q2. In a child with suspected acute rheumatic fever, which combination of major and
minor criteria would meet the revised Jones criteria for a first episode?
A. Carditis, polyarthritis, plus elevated ESR and arthralgia
B. Chorea alone plus prolonged PR interval
C. Erythema marginatum plus fever and elevated CRP
D. Subcutaneous nodules plus arthralgia and elevated ESR
Correct Answer: B. Chorea alone plus prolonged PR interval
Rationale: The revised Jones criteria require either 2 major criteria, or 1 major plus 2
minor, or chorea alone. Chorea is a major criterion and can suffice for diagnosis when
other causes are excluded. Option B includes chorea (major) plus a minor (prolonged PR
interval), meeting the 1 major + 2 minor rule if another minor is present, but chorea alone
is sufficient.
Why Wrong:
A - Carditis and polyarthritis are both major, but only one minor (elevated ESR) is
present; need 2 minors.
C - Erythema marginatum is major, but only one minor (fever) is listed; need 2
minors.
D - Subcutaneous nodules are major, but only one minor (arthralgia) is listed; need 2

Q3. Which parameter is most critical for interpreting a pediatric peak expiratory
flow (PEF) reading in asthma management?
A. Comparison to the child's personal best
B. Reference values based on height
C. Percentage of predicted for age
D. Pre-bronchodilator versus post-bronchodilator change
Correct Answer: A. Comparison to the child's personal best
Rationale: PEF variability is best assessed against the individual's personal best, which
reflects their optimal lung function. Population norms are less reliable due to wide
variability. Pre/post changes are useful for reversibility but not for interpreting a single
reading.
Why Wrong:
B - Height-based reference values are used for spirometry, not PEF interpretation.
C - Predicted values for age are not as accurate as personal best.
D - Pre/post change indicates reversibility, not the interpretation of a single PEF
value.
Reference: NAEPP EPR-3 Guidelines (2007) and GINA 2024
Q4. A child with type 1 diabetes presents with vomiting, abdominal pain, and deep
sighing respirations. Initial laboratory results show pH 7.1, bicarbonate 8 mEq/L, and
glucose 420 mg/dL. Which intravenous fluid and insulin regimen is most
appropriate?
A. 0.9% saline bolus 20 mL/kg, then 0.45% saline at 1.5 times maintenance, regular
insulin 0.1 units/kg/hr
B. 0.9% saline bolus 10 mL/kg, then 0.9% saline at maintenance, insulin lispro 0.15
units/kg subcutaneous
C. 0.45% saline bolus 20 mL/kg, then 0.9% saline at 1.5 times maintenance, regular
insulin 0.05 units/kg/hr
D. 0.9% saline bolus 20 mL/kg, then 0.9% saline at maintenance, regular insulin 0.01
units/kg/hr
Correct Answer: A. 0.9% saline bolus 20 mL/kg, then 0.45% saline at 1.5 times
maintenance, regular insulin 0.1 units/kg/hr
Rationale: DKA management requires isotonic fluid resuscitation (20 mL/kg) followed by
hypotonic fluid at 1.5 times maintenance to replace deficits, and continuous IV regular
insulin at 0.1 units/kg/hr. Option B uses subcutaneous insulin, which is not first-line in
DKA. Option C gives insufficient insulin and wrong bolus fluid. Option D gives too low
