interventions
Accreditation Meets US medical education standards for pediatric clerkship and advanced
practice nursing competencies.

,1. In RSV bronchiolitis, airway obstruction is primarily due to which of the
following?
Answer: Necrosis of bronchiolar epithelium and mucus plugging
RSV causes direct viral cytopathic effect leading to necrosis of epithelial cells,
sloughing, and mucus plugging, with inflammation causing edema. Smooth muscle
spasm is minimal in infants, unlike asthma.
2. Which diagnostic test is most definitive for confirming RSV infection in an infant
with bronchiolitis?
Answer: Reverse transcription-polymerase chain reaction (RT-PCR)
RT-PCR has the highest sensitivity and specificity for RSV detection. Rapid antigen
tests have variable sensitivity, especially in older infants; viral culture is slow; serology
is not useful in acute illness.
3. According to current AAP guidelines, supplemental oxygen should be initiated for
bronchiolitis patients when oxygen saturation persistently falls below what
threshold?
Answer: 90%
AAP guidelines recommend initiating supplemental oxygen for persistent SpO2 <90%
in infants with bronchiolitis. Higher thresholds lack evidence and may lead to
unnecessary interventions.
4. Which of the following interventions has strong evidence of reducing
hospitalization rates in acute viral bronchiolitis?
Answer: Nebulized hypertonic saline
Hypertonic saline (3%) improves mucociliary clearance and reduces airway edema;
meta-analyses show modest reduction in hospitalization. Epinephrine has short-term
benefits but does not reduce hospitalization; corticosteroids and leukotriene antagonists
are ineffective.

,5. Which of the following is a key criterion for discharging a child hospitalized for
bronchiolitis?
Answer: Adequate oral intake (e.g., at least 75% of usual volume)
Discharge criteria include sustained SpO2 >90% on room air and adequate oral intake
(75% of usual). Mild retractions or cough may persist and do not preclude discharge.
6. An infant presents with wheezing and respiratory distress but also has a daily
moist cough since birth. What diagnosis is most likely?
Answer: Cystic fibrosis
Daily moist cough from birth suggests chronic suppurative lung disease; cystic fibrosis
should be considered with recurrent wheeze, failure to thrive, and cough. Bronchiolitis
is acute; TEF typically presents with choking; foreign body is acute.
7. Palivizumab is recommended for RSV prophylaxis in which group of infants
under 12 months old?
Answer: Infants born at 28 weeks gestation
AAP guidelines recommend palivizumab for infants born at <29 weeks gestation who
are <12 months old at start of RSV season. Infants at 32 weeks are not indicated unless
they have CLD or CHD.
8. In infants hospitalized with RSV bronchiolitis, which factor is most strongly
associated with an increased risk of apnea?
Answer: Age less than 2 months
Young age, especially <2 months, is the strongest risk factor for apnea in RSV
bronchiolitis. Preterm birth and low birth weight also contribute but are less significant
than young age.
9. For an infant with bronchiolitis and copious nasal secretions, which nursing
intervention is most effective in improving oxygenation?
Answer: Nasopharyngeal suctioning with a soft catheter
Nasopharyngeal suctioning with a soft catheter effectively clears deep nasal secretions,
improving respiratory effort and oxygenation. Bulb syringe only clears anterior nares;
deep suctioning risks trauma; chest physiotherapy is not recommended in bronchiolitis.

, 10. Which pathophysiological mechanism best explains the expiratory wheezing
heard during auscultation in cases of viral bronchiolitis?
Answer: Peribronchial edema and airway narrowing from inflammation leading to
premature airway closure
Wheezing in bronchiolitis results from small airway inflammation, edema, and mucus
plugging leading to airway narrowing and early closure during expiration. Smooth
muscle contraction is minimal in viral bronchiolitis compared to asthma. Surfactant
deficiency is not a primary feature.
11. In a child presenting with respiratory distress due to RSV bronchiolitis, which
combination of findings most reliably predicts the need for intensive care admission?
Answer: Oxygen saturation 87% on 2 L/min nasal cannula, grunting, and lethargy
Hypoxemia despite supplemental oxygen, grunting (a sign of severe respiratory
distress), and altered mental status (lethargy) are indicators of impending respiratory
failure requiring ICU. Option A is moderate but not predictive of ICU need; C and D
are mild.
12. A child with RSV bronchiolitis develops worsening respiratory distress. A chest
radiograph shows bilateral hyperinflation, patchy atelectasis, and peribronchial
cuffing. Which complication is most important to consider?
Answer: Occult pneumothorax from air trapping and alveolar rupture
Hyperinflation and air trapping in bronchiolitis predispose to extra-alveolar air,
including pneumothorax, which can acutely worsen respiratory status. Bacterial
pneumonia is a later concern; ARDS is rare in RSV; bronchiolitis obliterans is a
long-term sequelae, not acute.
13. Which of the following interventions has been shown to reduce the duration of
hospitalization in infants hospitalized with RSV bronchiolitis?
Answer: Hypertonic saline (3%) nebulized every 8 hours
Nebulized hypertonic saline improves mucociliary clearance and reduces airway edema,
leading to modest reductions in length of stay. Inhaled epinephrine and corticosteroids
have not shown consistent benefit. High-flow nasal cannula improves work of breathing
but does not shorten hospitalization duration.
