RUPPEL’S MANUAL OF PULMONARY FUNCTION
TESTING 12TH EDITION – COMPREHENSIVE TEST
BANK & EXAM PREPARATION GUIDE
SECTION 1: INDICATIONS FOR PULMONARY FUNCTION TESTING
1. A 58-year-old male with a 40-pack-year smoking history presents with progressive
dyspnea on exertion and chronic cough. Which of the following is the PRIMARY
indication for pulmonary function testing in this patient?
A. Pre-operative evaluation for hernia repair
B. Detection of occupational lung disease
C. Evaluation of respiratory symptoms and risk factor assessment
D. Monitoring response to bronchodilator therapy
Answer: C
Rationale: The primary indication for PFT in this patient is the evaluation of respiratory
symptoms (dyspnea, chronic cough) in the presence of significant risk factors (heavy
smoking history). PFTs help characterize the nature and severity of pulmonary impairment.
,2. A 72-year-old female with severe aortic stenosis is scheduled for valve replacement
surgery. Pulmonary function testing is ordered. What is the MOST important reason for
performing PFTs in this patient?
A. To diagnose underlying asthma
B. Pre-operative risk assessment and stratification
C. To evaluate for pulmonary embolism
D. To assess for interstitial lung disease
Answer: B
Rationale: Pre-operative PFTs are critical for assessing surgical risk, particularly in
cardiothoracic surgeries. The results help predict postoperative pulmonary complications
and guide perioperative management.
3. A 45-year-old non-smoking female presents with progressive dyspnea, dry cough,
and fine crackles on auscultation. High-resolution CT shows diffuse interstitial
infiltrates. What is the primary role of PFTs in this scenario?
A. To confirm the diagnosis of pulmonary fibrosis
B. To quantify the severity of restrictive impairment and monitor progression
C. To rule out obstructive airway disease
D. To assess for bronchodilator reversibility
Answer: B
Rationale: In suspected interstitial lung disease, PFTs are essential for quantifying the
severity of restrictive ventilatory defect, monitoring disease progression, and assessing
response to therapy. The pattern typically shows reduced lung volumes with preserved or
increased FEV₁/FVC ratio.
4. According to the 2019 ATS-ERS guidelines, which of the following is a Class I
indication for performing spirometry?
A. Routine annual screening in all adults over 50
B. Evaluation of patients with signs and symptoms of lung disease
C. Assessment of fitness for scuba diving
D. Pre-employment screening in all industries
Answer: B
Rationale: The evaluation of patients with signs and symptoms of lung disease is a Class I
,(strongly recommended) indication for spirometry. Routine screening in asymptomatic
individuals is not generally recommended.
5. A 28-year-old competitive cyclist undergoes PFTs as part of a pre-participation
evaluation. Which parameter is MOST important for assessing exercise capacity in this
athlete?
A. FEV₁
B. DLCO
C. FVC
D. MVV
Answer: D
Rationale: Maximum Voluntary Ventilation (MVV) is the best correlate of exercise capacity
and ventilatory reserve. It reflects the integrated function of the respiratory muscles,
airways, and chest wall.
6. A patient with known COPD is being evaluated for lung volume reduction surgery.
Which PFT finding would be MOST consistent with a favorable outcome from this
procedure?
A. FEV₁ < 20% predicted with homogeneous emphysema
B. FEV₁ 20-45% predicted with upper lobe-predominant emphysema
C. DLCO > 80% predicted
D. Normal FEV₁/FVC ratio
Answer: B
Rationale: Patients with FEV₁ between 20-45% predicted and upper lobe-predominant
emphysema are optimal candidates for lung volume reduction surgery. Those with very
severe obstruction or homogeneous disease have poorer outcomes.
7. A 62-year-old male with a history of asbestos exposure presents with progressive
dyspnea and bilateral pleural plaques on chest imaging. Which PFT pattern would be
MOST consistent with asbestosis?
A. Obstructive pattern with reduced FEV₁/FVC
B. Restrictive pattern with reduced TLC and normal FEV₁/FVC
, C. Isolated reduction in DLCO with normal spirometry
D. Mixed obstructive-restrictive pattern
Answer: B
Rationale: Asbestosis typically produces a restrictive ventilatory defect characterized by
reduced TLC, FVC, and FEV₁ with a normal or elevated FEV₁/FVC ratio. DLCO is also
typically reduced due to the interstitial process.
8. Which of the following is an indication for bronchoprovocation challenge testing?
A. Routine screening for asthma in all children
B. Evaluation of a patient with normal spirometry and symptoms suggestive of asthma
C. Diagnosis of COPD
D. Assessment of response to inhaled corticosteroids
Answer: B
Rationale: Bronchoprovocation challenge testing is indicated when there is a clinical
suspicion of asthma but spirometry is normal or inconclusive. It helps confirm airway
hyperresponsiveness in patients with normal baseline lung function.
9. A 55-year-old patient with rheumatoid arthritis develops progressive dyspnea and a
non-productive cough. PFTs show a restrictive pattern with reduced DLCO. What is the
MOST likely diagnosis?
A. Rheumatoid arthritis-associated interstitial lung disease
B. COPD
C. Pulmonary embolism
D. Asthma
Answer: A
Rationale: Rheumatoid arthritis is associated with interstitial lung disease, which typically
presents with a restrictive pattern on PFTs (reduced TLC, FVC, and DLCO). This is a well-
recognized extra-articular manifestation of the disease.
10. Which of the following is a contraindication to performing spirometry?
A. Recent myocardial infarction within 1 week
B. Pregnancy
