1. A 3-year-old boy presents with a 6-month history of
greasy, floating stools and recurrent sinus infections treated
with amoxicillin. What diagnostic test should be ordered first?
A) Anti-transglutaminase IgA
B) Ciliary biopsy with molecular genetic testing
C) Pulmonary function testing
D) Sweat chloride testing
Answer: D) Sweat chloride testing
Rationale: The combination of steatorrhea (greasy, floating
stools) and recurrent sinopulmonary infections is highly suggestive
1
,of cystic fibrosis (CF). Sweat chloride test is the gold standard
diagnostic test for CF, with values >60 mEq/L being diagnostic .
2. A 2-week-old infant is noted to have a "clunk" sound when
the hips are adducted while applying downward and lateral
pressure on the knees. What sign is this?
A) Barlow sign
B) Ortolani sign
C) Galeazzi sign
D) Trendelenburg sign
Answer: B) Ortolani sign
Rationale: The Ortolani maneuver reduces a dislocated hip,
producing a palpable "clunk." Barlow maneuver dislocates the
hip. This is the standard screening for developmental dysplasia
of the hip (DDH) in infants .
3. A previously healthy 6-month-old presents with fever for 5
days, bilateral conjunctival injection without exudate, cracked
2
,red lips, polymorphous rash, and cervical lymphadenopathy.
What is the most likely diagnosis?
A) Measles
B) Kawasaki disease
C) Stevens-Johnson syndrome
D) Scarlet fever
Answer: B) Kawasaki disease
Rationale: This patient meets criteria for classic Kawasaki
disease: fever ≥5 days plus at least 4 of 5 principal clinical
features (conjunctival injection, oral mucous membrane changes,
rash, extremity changes, cervical lymphadenopathy).
4. A 10-year-old with known asthma presents with cough,
wheezing, and decreased peak flow. The parents report the
child has been using albuterol every 4 hours for 2 days with
minimal relief. What additional historical information is most
critical?
3
, A) Last dose of oral corticosteroids
B) Number of times the child has been hospitalized for asthma
C) Use of a spacer device with the inhaler
D) Presence of a fever
Answer: B) Number of times the child has been hospitalized for
asthma
Rationale: Prior hospitalizations, ICU admissions, and intubations
are key risk factors for fatal asthma and help determine severity
classification. This guides escalation of therapy and disposition
decisions.
5. A 14-year-old with type 1 diabetes presents with nausea,
vomiting, and abdominal pain. Fingerstick glucose is 450
mg/dL. Which historical feature most strongly suggests
diabetic ketoacidosis (DKA) rather than hyperglycemic
hyperosmolar state (HHS)?
A) Polyuria and polydipsia for 1 week
