Question 1.
In the majority of children, the first permanent teeth start to erupt at the age of 6 years.
Which of the following are the first permanent teeth to erupt in this time period?
A. First Molars
B. Second Molars
C. Lower or upper incisors
D. Canines
Correct Answer: A
Rationale:
The first molars are typically the first permanent teeth to erupt, usually around age 6. They
emerge behind the primary teeth and are often called "6-year molars."
Question 2.
The mother of a 12-month-old infant reports that her child had a high fever for several
days, which spontaneously resolved. After the fever resolved, the child developed a
maculopapular rash. Which of the following is the most likely diagnosis?
A. Fifth Disease (erythema infectious)
B. Roseola infantum (exanthema subitum)
C. Varicella
D. Infantile maculopapular rashes
Correct Answer: B
Rationale:
Roseola infantum is characterized by a high fever lasting 3–5 days that resolves abruptly,
followed by the appearance of a maculopapular rash. This classic sequence is pathognomonic
for roseola.
,Question 3.
A 4-month-old infant is brought to the clinic for a well-child checkup. Which of the
following tasks should a healthy 4-month-old infant be able to perform?
A. Sitting independently without support
B. Rolling from stomach to back
C. Exhibiting clear object permanence
D. Speaking two to three distinct words
Correct Answer: B
Rationale:
At 4 months, infants typically develop the gross motor skill to roll from prone (stomach) to
supine (back). Sitting independently occurs around 6 months. Object permanence develops
around 4–7 months but is not fully established until 8–12 months. Speaking distinct words
occurs around 12 months.
Question 4.
Which of the following is a classic clinical finding in an infant with hypertrophic pyloric
stenosis?
A. Sausage-shaped mass in the right flank
B. Olive-shaped mass in the epigastrium
C. Currant-jelly stools
D. Generalized abdominal distension
Correct Answer: B
Rationale:
Hypertrophic pyloric stenosis classically presents in infants aged 3–6 weeks with projectile, non-
bilious vomiting after feeding. A small, hard, olive-shaped mass can often be palpated in the
right upper quadrant or epigastrium. Sausage-shaped mass and currant-jelly stools are
characteristic of intussusception.
Question 5.
,Koplik's spots are associated with:
A. Poxvirus infections
B. Measles
C. Kawasaki's disease
D. Reye's syndrome
Correct Answer: B
Rationale:
Koplik's spots are small white lesions on the buccal mucosa that appear before the measles rash.
They are pathognomonic for measles, which presents with fever >101°F, coryza, cough,
conjunctivitis, rash, and Koplik's spots.
Question 6.
A child is diagnosed with Cystic Fibrosis. Both parents are asymptomatic carriers. What is
the pattern of genetic inheritance?
A. Autosomal dominant
B. Autosomal recessive
C. X-linked dominant
D. X-linked recessive
Correct Answer: B
Rationale:
Cystic Fibrosis is an autosomal recessive disorder. An individual must inherit two copies of the
mutated CFTR gene (one from each parent) to manifest the disease. Both parents are carriers
and asymptomatic.
Question 7.
A 6-year-old child presents with a "slapped cheek" rash on the face and a lacy, reticular
rash on the extremities. What is the most likely diagnosis?
A. Roseola infantum
B. Fifth disease (erythema infectiosum)
C. Measles
D. Scarlet fever
, Correct Answer: B
Rationale:
Fifth disease presents with a characteristic "slapped cheek" facial rash followed by a lacy,
reticular rash on the trunk and extremities. It is caused by parvovirus B19.
Question 8.
A 4-year-old child is brought to the pediatric clinic with a 2-day history of high fever,
barking cough, and inspiratory stridor that worsens at night. A neck radiograph reveals a
classic "steeple sign." What is the most common viral etiology of this presentation?
A. Respiratory syncytial virus (RSV)
B. Parainfluenza virus
C. Adenovirus
D. Bordetella pertussis
Correct Answer: B
Rationale:
The clinical picture of a barking cough, inspiratory stridor, and the characteristic subglottic
narrowing ("steeple sign") on radiography defines croup (laryngotracheobronchitis). Croup is
most frequently caused by human parainfluenza viruses (types 1 and 3). RSV is the primary
cause of bronchiolitis in infants. Bordetella pertussis causes whooping cough.
Question 9.
A nurse practitioner is assessing a child with suspected meningitis. Which of the following
findings is most concerning?
A. Positive Brudzinski sign
B. Mild headache
C. Low-grade fever
D. Mild photophobia
Correct Answer: A
Rationale:
