Difficulty: EasyPediatric Respiratory Disorders

A 5-month-old female is evaluated in an urgent care clinic during late January for a cough and fast breathing. According to her father, she developed nasal congestion and a mild fever three days prior. Since yesterday, she has been coughing frequently and seems to be working harder to breathe. She was born at 39 weeks gestation without complications and has received all age-appropriate vaccinations. Her 3-year-old sister recently recovered from a mild respiratory infection. Temperature is 37.6°C (99.7°F), pulse is 145/min, respiratory rate is 56/min, and oxygen saturation is 95% on room air. Examination shows clear, copious rhinorrhea. Lung auscultation reveals diffuse expiratory wheezes and crackles bilaterally, along with mild subcostal retractions. Which of the following is the most appropriate next step in the management of this patient?

  1. Supportive care with nasal suctioning and hydrationAnswer
  2. B
    Administration of nebulized albuterol
  3. C
    Initiation of oral dexamethasone
  4. D
    Prescription for a 7-day course of oral amoxicillin
  5. E
    Empiric treatment with oral azithromycin

Answer

Supportive care with nasal suctioning and hydration
The correct answer is to provide supportive care with nasal suctioning and hydration. This patient's presentation—a young infant during winter months exhibiting a viral prodrome followed by tachypnea, wheezing, and crackles—is the classic clinical picture of acute bronchiolitis. Respiratory syncytial virus (RSV) is the most common etiology. Because the disease is self-limiting and the patient is maintaining adequate oxygenation (oxygen saturation >90-92%) with only mild distress, outpatient supportive care is the standard of practice. Ensuring clear nasal passages via gentle suctioning helps infants, who are obligate nose breathers, feed comfortably and maintain hydration.

Step-by-Step Solution

1
Identify the clinical syndrome based on patient age and presentation.
A 5-month-old presenting in winter with a viral prodrome, followed by wheezing, crackles, and mild retractions.
These demographic factors and clinical findings are highly characteristic of acute viral bronchiolitis.
2
Assess the severity of the patient's respiratory distress.
The patient has mild retractions and tachypnea but is maintaining a safe oxygen saturation (95% on room air).
Determining severity dictates whether outpatient management or inpatient admission is required.
3
Determine the indicated evidence-based treatment.
Supportive care, including nasal suctioning and hydration.
Current guidelines strongly recommend against the routine use of medications such as bronchodilators, corticosteroids, and antibiotics for uncomplicated bronchiolitis.
