,Q1. In a toddler with acute cough and low-grade fever, which clinical cluster most
reliably differentiates viral from atypical bacterial pneumonia?
A. Tachypnea with retractions and crackles on auscultation
B. Gradual onset, non-productive cough, and absence of toxic appearance
C. Sudden high fever, pleuritic chest pain, and focal rales
D. Wheezing and prolonged expiratory phase without fever
Correct Answer: B. Gradual onset, non-productive cough, and absence of toxic
appearance
Rationale: Viral pneumonia typically presents with gradual onset, non-productive cough,
and mild systemic symptoms, whereas bacterial pneumonia often has sudden high fever,
toxic appearance, and focal findings. Atypical pathogens (e.g., Mycoplasma) often present
with gradual onset and non-productive cough. Tachypnea and retractions are nonspecific.
Wheezing suggests reactive airway disease or viral bronchiolitis.
Why Wrong:
A - Tachypnea and retractions are general signs of respiratory distress, not specific for
bacterial etiology.
C - Sudden high fever and focal rales are more typical of classic bacterial pneumonia,
not atypical.
D - Wheezing with prolonged expiration is characteristic of bronchiolitis or asthma,
not atypical pneumonia.

428.
Q2. Which combination of historical features and physical findings most strongly
supports a clinical diagnosis of bronchiolitis in a toddler, thereby reducing the need
for diagnostic testing?
A. Coryza, cough, wheezing, and low-grade fever following exposure to an older
sibling with a cold
B. Staccato cough, tachypnea, and conjunctivitis with no antecedent upper respiratory
symptoms
C. High fever, ill appearance, and focal consolidation on auscultation
D. Chronic cough, failure to thrive, and digital clubbing
Correct Answer: A. Coryza, cough, wheezing, and low-grade fever following exposure
to an older sibling with a cold
Rationale: Bronchiolitis is a clinical diagnosis in a toddler with viral prodrome (coryza,
cough) followed by wheezing and respiratory distress, especially during RSV season. The
presence of typical symptoms and exposure reduces the need for chest X-rays or labs.
Staccato cough and conjunctivitis suggest pertussis or chlamydial pneumonia. High fever
and focal consolidation indicate bacterial pneumonia. Chronic cough and clubbing
suggest cystic fibrosis.
Page 3
, Why Wrong:
B - Staccato cough and conjunctivitis are more indicative of pertussis or chlamydial
pneumonia.
C - High fever and focal consolidation suggest bacterial pneumonia, not bronchiolitis.
D - Chronic cough and failure to thrive point to a chronic condition like cystic
fibrosis.

Pediatrics, 134(5), e1474-e1502.
Q3. A toddler presents with a 2-day history of harsh, barky cough, stridor at rest, and
a hoarse voice. The child is anxious but not hypoxic. Which management step is most
appropriate?
A. Administer a single dose of oral dexamethasone and observe for 3-4 hours
B. Obtain a lateral neck radiograph to rule out epiglottitis before any treatment
C. Start empirical antibiotics to cover Haemophilus influenzae type b
D. Immediately arrange for intubation due to risk of complete airway obstruction
Correct Answer: A. Administer a single dose of oral dexamethasone and observe for
3-4 hours
Rationale: The presentation is classic for mild-to-moderate croup (viral
laryngotracheobronchitis). In moderate croup, a single dose of dexamethasone (0.6 mg/kg)
is the mainstay and often avoids the need for further intervention. Radiography is not
indicated in typical croup; it may be considered if the diagnosis is unclear, but it should
not delay steroids. Antibiotics are ineffective. Intubation is reserved for severe cases with
impending respiratory failure.
Why Wrong:
B - Imaging is not needed in typical croup and can delay treatment; epiglottitis is now
rare due to Hib vaccination.
C - Croup is viral; antibiotics are not indicated unless there is a secondary bacterial
infection.
D - Intubation is only for severe croup with significant distress, not for moderate
cases.
Reference: Bjornson, C.L., & Johnson, D.W. (2013). Croup in children. Canadian Medical
Association Journal, 185(15), 1317-1323.
Q4. Which vaccination status would most likely prevent a severe lower respiratory
tract infection caused by a pathogen that commonly affects toddlers and presents with
paroxysmal cough and inspiratory whoop?
A. Complete series of DTaP (diphtheria, tetanus, acellular pertussis)
B. Annual influenza vaccination
C. Pneumococcal conjugate vaccine (PCV13)
