A) Pulmonary function test
B) Pulse oximetry
C) Peak expiratory flow
D) Chest x-ray
B
Response:
Pulse oximetry is a useful tool for determining oxygenation and oxygen saturation. It can be used for continuous or intermittent monitoring. Pulmonary function testing measures respiratory flow and lung volumes and is indicated for asthma, cystic fibrosis, and chronic lung disease. Peak expiratory flow testing is used to monitor asthma control. Chest x-rays can show hyperinflation, atelectasis, pneumonia, foreign body, pleural effusion, and abnormal heart or lung size.
