A. Purely increased total lung capacity with normal diffusion
B. Isolated upper-airway obstruction only
C. Restrictive defect with reduced diffusion capacity
D. Normal lung volumes in every case
Correct Answer: C
Fibrotic interstitial lung disease commonly reduces lung volumes and gas diffusion.

Which complication or major adverse outcome is particularly associated with Interstitial lung disease (ILD)?
A. Systemic hypertension and cardiovascular risk
B. Pulmonary hypertension and chronic respiratory failure
C. Severe acute asthma with respiratory failure
D. Acute hypercapnic respiratory failure

A patient is diagnosed with Interstitial lung disease (ILD). Which is the most appropriate management principle?
A. Identify and remove reversible causes and use subtype-specific specialist therapy
B. Treat the underlying cause and drain the effusion when large, infected or causing significant symptoms
C. Use weight-management measures and positive airway pressure therapy when indicated
D. Use an inhaled corticosteroid-containing treatment strategy and provide a reliever appropriate to the regimen
Correct Answer: A
ILD treatment differs by cause; exposures, autoimmune disease and fibrotic subtypes require distinct management.

In a patient with suspected Interstitial lung disease (ILD), which investigation or diagnostic approach is most appropriate at this stage?
A. Clinical diagnosis; do not wait for chest imaging in an unstable patient
B. Thoracic ultrasound and diagnostic thoracentesis when the effusion is new, unexplained or clinically indicated
C. Sleep study or validated home sleep apnea testing in an appropriate patient
D. High-resolution CT chest with pulmonary-function testing
Correct Answer: D
HRCT characterizes interstitial patterns, while PFTs quantify restrictive impairment and diffusion abnormality.

A patient has progressive exertional dyspnea, dry cough, fine bibasal inspiratory crackles and restrictive pulmonary physiology. What is the most likely diagnosis?
A. Acute pulmonary embolism
B. Tension pneumothorax
C. Interstitial lung disease (ILD)

Which physical-examination percussion note is classically associated with a large pleural effusion?
A. Hyperresonance
B. Stony dullness
C. Tympany over the entire hemithorax
D. Normal resonance with bronchial breathing only
Correct Answer: B
Pleural fluid dampens percussion and classically produces a stony-dull note.

Which complication or major adverse outcome is particularly associated with Pleural effusion?
A. Empyema
B. Acute hypercapnic respiratory failure
C. Parapneumonic effusion or empyema
D. Obstructive shock from right ventricular failure
Correct Answer: A
Infected pleural fluid can become loculated and require chest-tube drainage.

A patient is diagnosed with Pleural effusion. Which is the most appropriate management principle?
A. Use an inhaled corticosteroid-containing treatment strategy and provide a reliever appropriate to the regimen
B. Use short-acting bronchodilators, systemic corticosteroids and controlled oxygen; give antibiotics when bacterial features are present
C. Start appropriate empiric antibiotics based on severity, comorbidity and local resistance patterns
D. Treat the underlying cause and drain the effusion when large, infected or causing significant symptoms
Correct Answer: D
Management depends on cause, size, symptoms and whether the pleural space is infected.
Medicine
Respiratory Medicine
In a patient with suspected Pleural effusion, which investigation or diagnostic approach is most appropriate at this stage?
A. Sleep study or validated home sleep apnea testing in an appropriate patient
B. Spirometry demonstrating variable expiratory airflow limitation when feasible
C. Thoracic ultrasound and diagnostic thoracentesis when the effusion is new, unexplained or clinically indicated
D. Clinical assessment with oxygenation; chest imaging and blood gases when severity or an alternative diagnosis is a concern
Correct Answer: C
Pleural-fluid analysis helps distinguish transudative from exudative causes and identifies infection or malignancy.

A patient has dyspnea with reduced breath sounds, stony dull percussion and a meniscus on chest imaging. What is the most likely diagnosis?
A. Interstitial lung disease (ILD)
B. Pleural effusion
C. Obstructive sleep apnea (OSA)
D. Asthma
Correct Answer: B
The examination and imaging pattern is typical of pleural fluid accumulation.

What is the key management principle in an unstable patient with suspected tension pneumothorax?
A. Treat immediately without waiting for radiographic confirmation
B. Wait for CT chest before intervention
C. Give oral antibiotics and observe
D. Schedule outpatient spirometry
Correct Answer: A
Tension pneumothorax is a clinical emergency where decompression must not be delayed by imaging.
Medicine
Respiratory Medicine
Which complication or major adverse outcome is particularly associated with Tension pneumothorax?
A. Obstructive shock from right ventricular failure
B. Empyema
C. Pulmonary hypertension and chronic respiratory failure
D. Cardiac arrest from obstructive shock
Correct Answer: D
Rising intrathoracic pressure impairs venous return and cardiac output.

A patient is diagnosed with Tension pneumothorax. Which is the most appropriate management principle?
A. Start appropriate empiric antibiotics based on severity, comorbidity and local resistance patterns
B. Start anticoagulation when PE is confirmed or strongly suspected and bleeding risk is acceptable; use reperfusion therapy for selected unstable patients
C. Immediate thoracic decompression followed by definitive chest drainage
D. Treat the underlying cause and drain the effusion when large, infected or causing significant symptoms
Correct Answer: C
Emergency decompression relieves obstructive pressure; tube thoracostomy provides definitive drainage.

In a patient with suspected Tension pneumothorax, which investigation or diagnostic approach is most appropriate at this stage?
A. Clinical assessment with oxygenation; chest imaging and blood gases when severity or an alternative diagnosis is a concern
B. Clinical diagnosis; do not wait for chest imaging in an unstable patient
C. Chest radiography plus severity-guided laboratory and microbiologic testing
D. Risk-stratified evaluation using clinical probability, D-dimer when appropriate and CT pulmonary angiography when indicated
Correct Answer: B
Tension physiology requires immediate decompression because imaging delay can be fatal.

A patient has sudden respiratory distress, hypotension, unilateral absent breath sounds and distended neck veins after chest trauma. What is the most likely diagnosis?
A. Tension pneumothorax
B. Asthma
C. Acute exacerbation of chronic obstructive pulmonary disease (COPD)
D. Community-acquired pneumonia
Correct Answer: A
Shock plus unilateral absent breath sounds in the right context is a clinical diagnosis of tension pneumothorax.

Which bedside finding in acute PE suggests higher-risk disease?
A. Normal blood pressure and no RV strain
B. Isolated mild sore throat
C. Chronic stable eczema
D. Hypotension with signs of right ventricular strain
Correct Answer: D
Hemodynamic instability and right ventricular dysfunction identify more severe pulmonary embolism.

Which complication or major adverse outcome is particularly associated with Acute pulmonary embolism?
A. Pulmonary hypertension and chronic respiratory failure
B. Systemic hypertension and cardiovascular risk
C. Obstructive shock from right ventricular failure
D. Severe acute asthma with respiratory failure
Correct Answer: C
A large PE can acutely raise pulmonary vascular resistance and cause right-heart failure and shock.

C. Identify and remove reversible causes and use subtype-specific specialist therapy
D. Use weight-management measures and positive airway pressure therapy when indicated
Correct Answer: B
Anticoagulation prevents clot extension; hemodynamic collapse may require urgent reperfusion.
