Question

question 11
identify the procedure used to assess the volume and air flow rate of the lungs.
a bronchoscopy
b pulmonary function test
c sputum culture
d arterial blood gases

Explanation:

• Option A: Bronchoscopy is used to visualize the airways, not assess lung volume and airflow rate.
• Option B: Pulmonary function test (PFT) is specifically designed to measure lung volumes, capacities, and airflow rates.
• Option C: Sputum culture is for detecting pathogens in sputum, not for lung volume/airflow assessment.
• Option D: Arterial blood gases (ABG) evaluate blood gas levels (oxygen, carbon dioxide, pH), not lung volume or airflow.

Answer:

B. pulmonary function test
