NAECB COPD Management 2 — Questions and Answers
Question 1: According to GOLD guidelines, what FEV1/FVC ratio post-bronchodilator confirms airflow obstruction in COPD?
- Less than 0.70 (Correct answer)
- Less than 0.80
- Less than 0.60
- Less than 0.75
Correct answer: Less than 0.70
A post-bronchodilator FEV1/FVC ratio below 0.70 is the GOLD standard criterion for confirming persistent airflow limitation in COPD.
Question 2: Which inhaled medication class is considered the cornerstone of maintenance therapy for stable COPD?
- Long-acting bronchodilators (Correct answer)
- Inhaled corticosteroids
- Short-acting beta-2 agonists
- Oral theophylline
Correct answer: Long-acting bronchodilators
Long-acting bronchodilators (LABAs and LAMAs) are the foundation of maintenance therapy because they reduce symptoms and exacerbation risk more effectively than other agents.
Question 3: A COPD patient has an FEV1 of 45% predicted. Which GOLD severity grade does this represent?
- GOLD Grade 3 (Severe) (Correct answer)
- GOLD Grade 2 (Moderate)
- GOLD Grade 4 (Very Severe)
- GOLD Grade 1 (Mild)
Correct answer: GOLD Grade 3 (Severe)
GOLD Grade 3 (Severe) corresponds to FEV1 30%–49% predicted; an FEV1 of 45% falls within this range.
Question 4: Pulmonary rehabilitation is MOST appropriate for a COPD patient who experiences dyspnea at what activity level?
- Walking on level ground at own pace (Correct answer)
- Only during strenuous exercise
- Only at rest
- During activities of daily living such as dressing
Correct answer: Walking on level ground at own pace
Pulmonary rehabilitation is indicated for patients with significant breathlessness during activities like walking on level ground, reflecting moderate-to-severe symptom burden.
Question 5: Which vaccine is recommended annually for all COPD patients to reduce exacerbation risk?
- Influenza vaccine (Correct answer)
- Pneumococcal vaccine only
- Hepatitis B vaccine
- Varicella vaccine
Correct answer: Influenza vaccine
Annual influenza vaccination is strongly recommended for all COPD patients because influenza infection is a leading trigger of acute exacerbations.
Question 6: What is the primary physiological mechanism causing hyperinflation in COPD?
- Air trapping due to expiratory flow limitation (Correct answer)
- Increased respiratory muscle strength
- Excessive mucus clearing
- Increased alveolar surface area
Correct answer: Air trapping due to expiratory flow limitation
Expiratory flow limitation prevents complete emptying of alveoli, causing progressive air trapping and hyperinflation that flattens the diaphragm.
Question 7: Which of the following best describes the COPD Assessment Test (CAT) score interpretation?
- Higher scores indicate greater symptom burden (Correct answer)
- Lower scores indicate worse quality of life
- Scores above 5 are considered low impact
- Only scores above 30 are clinically significant
Correct answer: Higher scores indicate greater symptom burden
CAT scores range from 0–40; higher scores reflect more severe symptoms and greater impact on health status, with scores ≥10 considered high impact.
