Introduction and Exam Overview
The Barkley Respiratory Practice Exam is designed to strengthen
clinical reasoning and diagnostic decision-making skills for
, respiratory disorders across the lifespan. Barkley & Associates is
recognized as a pioneer in NP review, with over 20 years of
experience preparing more than 135,000 NPs for certification
success. Their curriculum review books include over 600
practice questions covering assessment, labs/diagnostics,
management/treatment, pharmacology, and professional
practice for Adult-Gerontology Primary Care NPs and over 325
practice questions for PMHNPs.
Barkley's Pulmonary Disorders review materials emphasize a
systematic approach to respiratory assessment, interpretation
of pulmonary function tests, arterial blood gas analysis, and
evidence-based management of acute and chronic respiratory
conditions. The Barkley 3P (Pathophysiology, Pharmacology,
and Physical Assessment) review exams include respiratory
content covering COPD, asthma, pneumonia, pulmonary
embolism, and ventilator management.
Core respiratory topics tested include:
• Obstructive lung diseases (COPD, asthma, bronchiectasis, cystic
fibrosis)
• Restrictive lung diseases (IPF, sarcoidosis, pneumoconiosis)
• Respiratory infections (pneumonia, TB, influenza, COVID-19)
• Pulmonary vascular disorders (PE, pulmonary hypertension)
• Pleural disorders (effusion, pneumothorax, empyema)
• Respiratory failure and mechanical ventilation
• Respiratory pharmacology and diagnostic testing
This comprehensive practice exam contains 200 questions
covering all respiratory content areas. Each question includes
the correct answer marked in italics with a detailed rationale in
bold.
,Section 1: Obstructive Lung Diseases (Questions 1-40)
1. A patient with chronic obstructive pulmonary disease
(COPD) presents with worsening dyspnea and a productive
cough. Which pathophysiological mechanism is primarily
responsible for the airflow limitation in this patient?
A. Destruction of alveolar walls leading to decreased surface
area for gas exchange
B. Airway inflammation, mucus hypersecretion, and airway wall
thickening
C. Pulmonary vasoconstriction leading to increased pulmonary
artery pressure
D. Decreased surfactant production causing alveolar collapse
Correct Answer: B
Rationale: Airflow limitation in COPD results from a
combination of airway inflammation, mucus
hypersecretion, and airway wall thickening. While alveolar
destruction occurs in emphysema, the primary mechanism
involves chronic inflammation and structural changes in the
airways.
2. A 55-year-old male with a 30-pack-year smoking history
presents with dyspnea on exertion and chronic cough.
Spirometry shows FEV1/FVC = 65% post-bronchodilator.
Which pathophysiologic mechanism best explains his
airflow obstruction?
A. Airway hyperresponsiveness to allergens
B. Loss of elastic recoil and small airway collapse
C. Thickened basement membrane and eosinophilic
, inflammation
D. Restrictive lung disease from interstitial fibrosis
Correct Answer: B
Rationale: FEV1/FVC <70% post-bronchodilator indicates
COPD. Mechanisms include loss of elastic recoil
(emphysema) and small airway fibrosis (chronic bronchitis),
leading to air trapping and collapse during expiration.
3. A 65-year-old male with a 40-pack-year smoking history
presents with chronic productive cough and dyspnea on
exertion. Which diagnosis is most likely?
A. Asthma
B. COPD
C. Lung cancer
D. Bronchiectasis
Correct Answer: B
Rationale: Chronic productive cough and dyspnea in a long-
term smoker suggest COPD. Spirometry showing FEV1/FVC
<0.70 confirms the diagnosis.
4. A patient with COPD has an FEV1/FVC ratio of 0.55. What
does this indicate?
A. Normal lung function
B. Obstructive lung disease
C. Restrictive lung disease
D. Mixed pattern
Correct Answer: B
Rationale: FEV1/FVC <0.70 indicates obstructive lung
disease. A ratio of 0.55 is consistent with COPD.
