1. Mycoplasma pneumoniae
2. Respiratory syncytial virus (RSV)
3. Influenza virus
4. Adenovirus

Answer: b. Respiratory syncytial virus (RSV)

Explanation: RSV is the leading cause of bronchiolitis in infants and young children, typically affecting those under 2 years of age. It causes inflammation and obstruction of small airways, leading to wheezing, cough, and respiratory distress.

1. Recurrent pneumonia with Pseudomonas aeruginosa
2. Chronic cough and sinusitis
3. Meconium ileus in the neonatal period
4. All of the above

Answer: d. All of the above

Explanation: Cystic fibrosis presents with a spectrum of respiratory and gastrointestinal symptoms. Recurrent pneumonia, sinusitis, chronic cough, and neonatal meconium ileus are hallmark features. The diagnosis is confirmed with sweat chloride testing and genetic analysis.

Question 3: A 5-year-old child presents with episodic wheezing, cough, and shortness of breath that worsens at night and with exercise. Pulmonary function testing shows reversible airflow obstruction. What is the most likely diagnosis?

1. Chronic bronchitis
2. Asthma
3. Cystic fibrosis
4. Bronchiolitis obliterans

Answer: b. Asthma

Explanation: The episodic nature, triggers, nocturnal symptoms, and reversibility of airflow obstruction on PFTs are characteristic of pediatric asthma. Management involves inhaled corticosteroids and bronchodilators.

Diagnostic Approaches in Pediatric Pulmonary Disorders

1. History and Physical Examination

A thorough assessment helps differentiate between obstructive, restrictive, and vascular causes.

2. Pulmonary Function Tests (PFTs)

- Spirometry: Key for diagnosing obstruction/restriction. - Lung volumes and diffusion capacity: For interstitial diseases.

3. Imaging Studies

- Chest X-ray: First-line for many conditions. - High-resolution CT: For detailed lung parenchyma evaluation. - MRI: Useful in specific cases to avoid radiation.

4. Laboratory Tests
