Test: Interstitial Lung Disease Diagnosis

20 questions

Question 1: Chronic hypoxia is the underlying cause of clubbing of the fingers in most cases.

A. Ano

B. Ne

Explanation: The study materials explicitly state under 'CLINICAL PEARL 2-5 Clubbing of the Fingers' that 'Chronic hypoxia is the underlying cause in most cases.'

Question 2: For Interstitial Lung Disease (ILD) patients exhibiting a restrictive pattern on PFTs, the FEV1/FVC ratio is typically decreased.

A. Ano

B. Ne

Explanation: In a restrictive pattern, the FEV1/FVC ratio is increased, not decreased. Both FEV1 and FVC are low, with FVC being lower than FEV1.

Question 3: The differential diagnosis for clubbing of the fingers includes pulmonary diseases such as lung cancer, CF, and interstitial lung disease.

A. Ano

B. Ne

Explanation: According to CLINICAL PEARL 2-5, the differential diagnoses for clubbing include pulmonary diseases like lung cancer, CF, ILD (Interstitial Lung Disease), empyema, sarcoidosis, and mesothelioma.

Question 4: Transbronchial biopsy consistently provides an ample amount of tissue, which enhances its overall utility in the diagnosis of Interstitial Lung Disease.

A. Ano

B. Ne

Explanation: Transbronchial biopsy obtains a limited amount of tissue, which restricts its utility in diagnosing Interstitial Lung Disease.

Question 5: The presence of finger clubbing is a definitive indicator that a patient has interstitial lung disease.

A. Ano

B. Ne

Explanation: Finger clubbing is listed as a potential finding in various pulmonary diseases, including interstitial lung disease, but it may also be an idiopathic or primary finding, such as in familial clubbing, or due to other conditions like congenital heart disease or biliary cirrhosis. Therefore, it is not a definitive indicator solely for interstitial lung disease.
