Question 1: A 2-day-old male infant, born at 39 weeks gestation via
spontaneous vaginal delivery, is being evaluated for poor feeding and
jitteriness. The mother is positive for hepatitis B surface antigen. Which of the
following is the most appropriate initial management for this infant?
A. Administer hepatitis B immune globulin (HBIG) and the first dose of hepatitis B
vaccine within 12 hours of birth
B. Administer the first dose of hepatitis B vaccine only, and repeat the vaccine series at 1
month
C. Administer HBIG only and delay the vaccine until the infant is 1 month old
D. Administer hepatitis B vaccine and HBIG at 1 month of age
CORRECT ANSWER: A. Administer hepatitis B immune globulin (HBIG) and
the first dose of hepatitis B vaccine within 12 hours of birth
Rationale:For an infant born to a hepatitis B surface antigen (HBsAg)-positive mother,
immunoprophylaxis with both HBIG and the hepatitis B vaccine should be administered
within 12 hours of birth, regardless of birth weight. This combination provides
immediate passive immunity and active immunity, significantly reducing the risk of
perinatal transmission.
Question 2: A 6-month-old infant is brought to the clinic for a well-child visit.
The mother reports that the infant has been exclusively breastfed. Which of
the following is the most important supplement to recommend at this age?
A. Vitamin D
B. Vitamin C
C. Iron
D. Fluoride
CORRECT ANSWER: C. Iron
Rationale:Exclusively breastfed infants have sufficient iron stores for the first 4 to 6
months of life. After 6 months, these stores become depleted, and iron supplementation
(1 mg/kg/day) is recommended to prevent iron deficiency anemia, as breast milk is a
poor source of iron. Vitamin D is recommended from birth.
Question 3: A 4-year-old child presents with a 3-day history of fever,
irritability, and a maculopapular rash that started on the face and spread
downward. The mother reports the child had a cough, coryza, and
conjunctivitis before the rash appeared. Which of the following is the most
likely diagnosis?
,A. Rubella
B. Measles
C. Roseola infantum
D. Fifth disease
CORRECT ANSWER: B. Measles
Rationale:Measles (rubeola) is characterized by a prodrome of cough, coryza,
conjunctivitis (the "3 Cs"), and Koplik spots, followed by a maculopapular rash that
begins on the face and spreads cephalocaudally. Rubella presents with a milder
prodrome and lymphadenopathy. Roseola typically begins with high fever followed by a
rash as the fever subsides.
Question 4: A 2-year-old child is brought to the emergency department after
ingesting a bottle of prenatal vitamins. The mother is unsure of the quantity
ingested. Which of the following is the primary toxicity concern with prenatal
vitamin ingestion?
A. Hypercalcemia
B. Iron toxicity
C. Vitamin A toxicity
D. Vitamin D toxicity
CORRECT ANSWER: B. Iron toxicity
Rationale:Prenatal vitamins contain a significant amount of iron, which is the most
dangerous component in an acute ingestion. Iron toxicity can lead to severe
gastrointestinal necrosis, metabolic acidosis, and cardiovascular collapse. Iron is the
leading cause of poisoning deaths in children.
Question 5: A 15-year-old female reports to the school nurse with a headache,
stiff neck, and photophobia. On examination, she is febrile and has a petechial
rash on her trunk. Which of the following is the most appropriate immediate
action?
A. Administer oral acetaminophen and send her back to class
B. Obtain a CT scan of the head
C. Administer intravenous antibiotics immediately and arrange for transport to the
emergency department
D. Perform a lumbar puncture in the clinic before transfer
CORRECT ANSWER: C. Administer intravenous antibiotics immediately and
arrange for transport to the emergency department
Rationale:The presentation of fever, stiff neck, photophobia, and petechial rash is highly
suggestive of meningococcal meningitis/sepsis. This is a medical emergency. Antibiotics
should be administered as soon as possible, preferably before transport or in the
emergency department, to reduce mortality. Do not delay antibiotics for a CT scan or
lumbar puncture in a hemodynamically unstable patient.
,Question 6: A 6-month-old infant with a history of a small, asymptomatic
ventricular septal defect (VSD) is seen for a routine check-up. The mother is
concerned about feeding the infant. Which of the following is the most
appropriate feeding advice regarding the VSD?
A. Restrict fluid intake to prevent heart failure
B. Encourage small, frequent feedings to minimize fatigue
C. Provide high-calorie formula to promote growth
D. No special feeding modifications are needed
CORRECT ANSWER: D. No special feeding modifications are needed
Rationale:A small, asymptomatic VSD is hemodynamically insignificant and does not
require any special feeding modifications, fluid restriction, or caloric enhancement.
Large VSDs may cause tachypnea and poor feeding, requiring high-calorie formulas or
surgical intervention, but a small VSD is typically managed with routine infant feeding.
Question 7: A 9-year-old boy is brought to the clinic with a 2-week history of
joint pain and swelling in his right knee, along with a low-grade fever. He
reports a sore throat about a month ago, which was not treated with
antibiotics. Which of the following laboratory findings would most support the
suspected diagnosis?
A. Elevated anti-streptolysin O (ASO) titer
B. Positive blood culture for Staphylococcus aureus
C. Elevated erythrocyte sedimentation rate (ESR) with negative antinuclear antibody
(ANA)
D. Positive rheumatoid factor (RF)
CORRECT ANSWER: A. Elevated anti-streptolysin O (ASO) titer
Rationale:The presentation of migratory polyarthritis, fever, and a history of recent
pharyngitis is classic for acute rheumatic fever (ARF). The diagnosis is supported by
evidence of a preceding group A streptococcal infection, which is confirmed by elevated
or rising ASO titers. Blood cultures would be negative in ARF, and RF and ANA are
typically negative, as this is not juvenile idiopathic arthritis.
Question 8: A 12-month-old child has received the first dose of the MMR
vaccine at 12 months of age. The mother asks when the next dose is due.
According to the standard immunization schedule, when should the second
dose of MMR be administered?
A. At 18 months of age
B. At 4 to 6 years of age
C. At 11 to 12 years of age
D. At 15 months of age
CORRECT ANSWER: B. At 4 to 6 years of age
, Rationale:The routine childhood immunization schedule recommends the first dose of
MMR at 12-15 months of age and the second dose at 4-6 years of age (school entry).
The second dose is not given at 18 months or 15 months in the standard schedule.
Question 9: A 5-year-old child is brought to the emergency department with a
sudden onset of inspiratory stridor, barking cough, and low-grade fever. The
child appears anxious and is sitting upright in a tripod position. Which of the
following is the most appropriate initial management?
A. Administer nebulized epinephrine and oral dexamethasone
B. Perform a lateral neck X-ray
C. Prepare for an emergency tracheostomy
D. Administer a racemic epinephrine nebulizer and observe for improvement
CORRECT ANSWER: A. Administer nebulized epinephrine and oral
dexamethasone
Rationale:The child is presenting with classic symptoms of moderate to severe croup
(laryngotracheobronchitis), including stridor, barking cough, and the tripod position.
The standard treatment for moderate to severe croup is a single dose of oral
dexamethasone (corticosteroid) and nebulized epinephrine to reduce subglottic edema.
A lateral neck X-ray is not indicated initially and may worsen distress.
Question 10: A newborn is noted to have a "milk crust" on the scalp, consisting
of thick, yellow, greasy scales. The surrounding skin is mildly erythematous.
What is the most likely diagnosis and management?
A. Atopic dermatitis; treat with topical corticosteroids
B. Seborrheic dermatitis; treat with gentle washing and application of mineral oil
C. Tinea capitis; treat with oral antifungal medication
D. Impetigo; treat with topical mupirocin
CORRECT ANSWER: B. Seborrheic dermatitis; treat with gentle washing and
application of mineral oil
Rationale:The classic presentation of thick, yellow, greasy scales on the scalp, often
called "cradle cap," is consistent with seborrheic dermatitis. It is common in infants and
is usually managed with gentle washing, softening the scales with mineral oil or baby
shampoo, and mild brushing. Atopic dermatitis is pruritic and typically involves the
cheeks and flexural areas.
Question 11: A 14-year-old boy with a history of asthma presents with a 2-day
history of fever, headache, and a painful, vesicular rash on the right side of his
face, which is limited to the dermatome of the ophthalmic branch of the
trigeminal nerve. Which of the following is the most appropriate management
to prevent a serious complication?
A. Oral acyclovir within 72 hours of rash onset
B. Oral antibiotics for secondary bacterial infection
