Answers 2026 with rationales
Q1. Simple spirometry can be used to measure any of the following EXCEPT:
A. Residual volume
B. Vital capacity
C. Tidal volume
D. Inspiratory reserve volume
,,answer,,,: A. Residual volume (cannot be measured by simple spirometry;
requires body plethysmography or gas dilution)
Q2. The NP notes that a patient's FEV1/FVC ratio is severely reduced. Which
condition is most likely? A. Chronic asthma
B. Pulmonary hypertension
C. Pneumonia
D. Morbid obesity
,,answer,,,: A. Chronic asthma (reduced FEV1/FVC ratio indicates obstructive
lung disease)
Q3. The NP is seeing a patient with chronic bronchitis who needs spirometry.
What PFT findings are anticipated?
A. Decreased diffusing capacity
B. Decreased total lung capacity (TLC)
,C. Decreased forced expiratory flow (FEV1)
D. Increased lung compliance
,,answer,,,: C. Decreased FEV1 (obstructive pattern with reduced airflow)
Q4. A patient with normal lungs should be able to exhale what percentage of forced
vital capacity within the first second?
A. 50%
B. 60%
C. 70%
D. 80%
,,answer,,,: D. 80% (normal FEV1/FVC ratio is approximately 80%)
Q5. The NP reviews PFT results showing reduced FEV1, FVC, and TLC with a
normal FEV1/FVC ratio. This reflects:
A. Restrictive lung disease
B. Obstructive lung disease
C. Invalid test
D. Combined obstructive-restrictive disease
,,answer,,,: A. Restrictive lung disease (all volumes reduced but ratio preserved)
Q6. Asthma is a chronic disease characterized by:
A. Intermittent, reversible airflow obstruction
B. Bronchial scarring
C. Air trapping
D. Airway infection
,,answer,,,: A. Intermittent, reversible airflow obstruction
,Q7. Symptoms common to both intrinsic and extrinsic asthma include:
A. Wheezing
B. Dizziness
C. Slowed breathing
D. Elevated heart rate
,,answer,,,: A. Wheezing
Q8. Which drugs are commonly associated with medication-induced interstitial
lung disease (ILD)? (Select all that apply)
A. Methotrexate
B. Lisinopril
C. Amiodarone
D. Warfarin
E. Omeprazole
F. Nitrofurantoin
,,answer,,,: A, C, F. Methotrexate, Amiodarone, Nitrofurantoin
Q9. Interstitial lung disease (ILD) includes infectious and neoplastic lung diseases.
(True/False)
A. True
B. False
,,answer,,,: B. False (ILD typically excludes infectious and neoplastic diseases)
Q10. A subjective finding in interstitial lung disease is rhonchi in the upper
posterior airways. (True/False)
A. True
, B. False
,,answer,,,: B. False (rhonchi are an objective finding, not subjective)
Q11. Choose the types of ILD commonly associated with smoking: (Select all that
apply)
A. Pulmonary Langerhans cell histiocytosis
B. Desquamative interstitial pneumonia
C. Respiratory bronchiolitis-interstitial lung disease
D. Sarcoidosis
E. Pneumoconioses
F. Hypersensitivity pneumonitis
,,answer,,,: A, B, C. Pulmonary Langerhans cell histiocytosis, Desquamative
interstitial pneumonia, Respiratory bronchiolitis-ILD
Q12. Interstitial lung disease refers to any disease affecting the pulmonary:
A. Alveoli
B. Bronchioles
C. Interstitium
D. Pleura
,,answer,,,: C. Interstitium
Q13. The four key diagnostic tests for interstitial lung disease are pulmonary
function tests, high-resolution CT scan, bronchoalveolar lavage, and:
A. Chest x-ray
B. Lung biopsy
C. Sputum culture
D. Bronchoscopy
