Pneumologia SBPT Practice Questions - Título de Especialista em Pneumologia e Tisiologia (Sociedade Brasileira de Pneumologia e Tisiologia AMB) Exam - Pneumologia SBPT Practice Questions - Título de Especialista em Pneumologia e Tisiologia (Sociedade Brasileira de Pneumologia e Tisiologia AMB) Exam

Question 1

A 45-year-old man undergoes spirometry for evaluation of chronic cough. According to the Sociedade Brasileira de Pneumologia e Tisiologia (SBPT) and ATS/ERS guidelines for pulmonary function testing, what are the minimum repeatability criteria required for Forced Vital Capacity (FVC) and Forced Expiratory Volume in 1 second (FEV1) across acceptable maneuvers?

The difference between the two largest FVC values and the two largest FEV1 values must both be within 150 mL (or 100 mL if FVC is < 1.0 L). The difference between the two largest FVC values and the two largest FEV1 values must both be within 250 mL regardless of absolute volume. The variation coefficient among all performed maneuvers must not exceed 10% for peak expiratory flow (PEF). The difference between the highest and lowest FEV1 values across all attempts must be less than 5% of predicted normal values.

Correct Answer:

The difference between the two largest FVC values and the two largest FEV1 values must both be within 150 mL (or 100 mL if FVC is < 1.0 L).

Question 2

A 38-year-old woman with recurrent wheezing undergoes pre- and post-bronchodilator spirometry. Her baseline FEV1 is 2.00 L. Following the inhalation of 400 mcg of salbutamol via metered-dose inhaler with a spacer, her FEV1 increases to 2.28 L (an absolute gain of 280 mL and a 14% increase). According to SBPT guidelines, how should this bronchodilator response be classified?

Positive significant bronchodilator response, satisfying both the absolute volume (≥ 200 mL) and percentage (≥ 12%) thresholds. Negative bronchodilator response, because a minimum absolute gain of 350 mL is required to confirm airway reversibility. Borderline response, requiring a repeat trial with an anticholinergic agent (ipratropium bromide) before confirming reversibility. Positive response based solely on the percentage increase, as the absolute volume requirement is waived when baseline FEV1 is under 2.5 L.

Correct Answer:

Positive significant bronchodilator response, satisfying both the absolute volume (≥ 200 mL) and percentage (≥ 12%) thresholds.

Question 3

A 74-year-old asymptomatic non-smoker undergoes spirometry before elective surgery. The pre-bronchodilator FEV1/FVC ratio is 0.68, and the post-bronchodilator FEV1/FVC ratio is 0.68. The Lower Limit of Normal (LLN, 5th percentile) for the FEV1/FVC ratio calculated for his age, sex, and height is 0.65. How should this spirometry result be interpreted regarding the presence of obstructive ventilatory defect?

Normal ventilatory pattern without obstruction, because the post-bronchodilator FEV1/FVC ratio is above the Lower Limit of Normal (LLN). Definite obstructive ventilatory defect, because the post-bronchodilator FEV1/FVC ratio is below the fixed cutoff of 0.70. Mixed restrictive and obstructive defect, necessitating immediate whole-body plethysmography. Isolated small airway disease, because fixed cutoffs supersede lower limit of normal calculations in geriatric populations.

Correct Answer:

Normal ventilatory pattern without obstruction, because the post-bronchodilator FEV1/FVC ratio is above the Lower Limit of Normal (LLN).

Question 4

A 52-year-old man with systemic sclerosis undergoes pulmonary function testing. Spirometry shows FEV1 58% of predicted, FVC 54% of predicted, and FEV1/FVC ratio 0.82 (normal). To formally confirm a restrictive ventilatory defect, which measurement on body plethysmography is mandatory?

Total Lung Capacity (TLC) below the lower limit of normal (< LLN or < 80% of predicted). Residual Volume (RV) below 65% of predicted with preserved Vital Capacity. Functional Residual Capacity (FRC) below 70% of predicted combined with normal airway resistance. Diffusing capacity of the lung for carbon monoxide (DLCO) below 60% of predicted.

Correct Answer:

Total Lung Capacity (TLC) below the lower limit of normal (< LLN or < 80% of predicted).

Question 5

A 62-year-old heavy smoker with severe COPD undergoes whole-body plethysmography. The report demonstrates: TLC = 135% of predicted, FVC = 62% of predicted, RV = 210% of predicted, and RV/TLC ratio = 58% (normal upper limit 35%). How are these plethysmographic volume abnormalities correctly categorized?

Pulmonary hyperinflation combined with severe air trapping. Isolated air trapping without pulmonary hyperinflation. Mixed restrictive-obstructive ventilatory defect. Pseudonormalization of lung volumes secondary to chest wall restriction.

Correct Answer:

Pulmonary hyperinflation combined with severe air trapping.
