A 9-month-old girl is brought to the clinic in late December with a 3-day history of nasal congestion, low-grade fever, and a prominent cough. Her parents report that today she has been breathing faster than usual and they can hear a wheezing sound. Her temperature is 37.8°C (100.0°F), heart rate is 130/min, respiratory rate is 54/min, and oxygen saturation is 96% on room air. Physical examination reveals mild subcostal retractions and diffuse expiratory wheezes and crackles bilaterally. She is alert, interacting appropriately with her parents, and taking her formula without difficulty. Which of the following is the most appropriate next step in management?

  1. A
    Administration of nebulized albuterol
  2. B
    Administration of oral dexamethasone
  3. Supportive care with nasal suctioning and hydrationCevap
  4. D
    Prescription of oral amoxicillin
  5. E
    Prescription of oral azithromycin

Cevap

Supportive care with nasal suctioning and hydration
The patient's clinical presentation of a viral prodrome followed by lower respiratory tract signs (wheezing, crackles) in an infant under two years of age during the winter months is highly characteristic of acute bronchiolitis, most commonly caused by Respiratory Syncytial Virus (RSV). This infant is maintaining adequate oxygenation (SpO2 > 90%), is well-hydrated, and does not have severe respiratory distress. The cornerstone of management for bronchiolitis is supportive care, which includes maintaining hydration, relieving nasal congestion with saline drops and suctioning, and closely monitoring for worsening respiratory distress. Medications such as bronchodilators, corticosteroids, and antibiotics have no proven benefit in the routine management of bronchiolitis and are not recommended.

Adım Adım Çözüm

1
Analyze the patient's demographics, timing, and symptoms.
A 9-month-old infant presenting in winter with a viral prodrome followed by wheezing, tachypnea, and retractions.
To recognize the classic presentation of acute viral bronchiolitis, typically caused by Respiratory Syncytial Virus (RSV).
2
Assess the severity of the illness.
The patient has mild respiratory distress (respiratory rate 54/min, mild retractions) but is well-oxygenated (96% on room air), well-hydrated, and active.
To determine whether inpatient management, respiratory support, or simple outpatient management is required.
3
Determine the appropriate management based on current guidelines.
The standard of care for mild viral bronchiolitis is supportive.
Interventions like bronchodilators, corticosteroids, and antibiotics lack efficacy for bronchiolitis and are not recommended for routine use.
