Free ITE Pulmonology Questions and Answers — Questions and Answers
Question 1: Which test is the most appropriate initial diagnostic tool for suspected pulmonary embolism?
- Chest X-ray
- D-dimer test (Correct answer)
- CT pulmonary angiography
- Ventilation-perfusion scan
Correct answer: D-dimer test
The D-dimer test is the most appropriate initial diagnostic tool for suspected pulmonary embolism (PE) in patients with a low or intermediate pre-test probability. A negative D-dimer test can effectively rule out PE, avoiding the need for more invasive imaging. However, a positive D-dimer requires further investigation.
Question 2: Which medication is the cornerstone of management for persistent asthma?
- Short-acting beta agonists (SABAs)
- Leukotriene receptor antagonists
- Inhaled corticosteroids (ICS) (Correct answer)
- Long-acting muscarinic antagonists (LAMAs)
Correct answer: Inhaled corticosteroids (ICS)
Inhaled corticosteroids (ICS) are the cornerstone of management for persistent asthma. They work by reducing airway inflammation, which is a key underlying pathology in asthma. Regular use of ICS helps to control symptoms, prevent exacerbations, and improve lung function over time.
Question 3: What is the most common cause of community-acquired pneumonia (CAP) in adults?
- Mycoplasma pneumoniae
- Streptococcus pneumoniae (Correct answer)
- Haemophilus influenzae
- Legionella pneumophila
Correct answer: Streptococcus pneumoniae
Streptococcus pneumoniae is consistently identified as the most common bacterial cause of community-acquired pneumonia (CAP) in adults. This pathogen is responsible for a significant portion of pneumonia cases, often presenting with classic symptoms like fever, cough, and pleuritic chest pain. Vaccination against S. pneumoniae is an important preventive measure.
Question 4: Which finding is characteristic of obstructive lung disease on spirometry?
- Increased FEV1/FVC ratio
- Normal FEV1 with reduced FVC
- Decreased FEV1/FVC ratio (Correct answer)
- Increased total lung capacity
Correct answer: Decreased FEV1/FVC ratio
A decreased FEV1/FVC ratio is the characteristic finding of obstructive lung disease on spirometry. This indicates that the forced expiratory volume in one second (FEV1) is disproportionately reduced compared to the forced vital capacity (FVC), reflecting airflow limitation due to airway obstruction. This ratio is key for diagnosing conditions like COPD and asthma.
Question 5: What is the first-line treatment for acute exacerbation of chronic obstructive pulmonary disease (COPD)?
- Systemic corticosteroids and antibiotics (Correct answer)
- Inhaled corticosteroids and beta-blockers
- Bronchodilators and leukotriene antagonists
- Antihistamines and nasal decongestants
Correct answer: Systemic corticosteroids and antibiotics
The first-line treatment for acute exacerbation of chronic obstructive pulmonary disease (COPD) typically involves systemic corticosteroids and antibiotics. Corticosteroids reduce airway inflammation, while antibiotics are often prescribed to cover potential bacterial infections, which frequently trigger exacerbations. Bronchodilators are also crucial for symptom relief.
