Answer to Question 1

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.

Answer to Question 2

C
Response:
Wheezing is not a symptom of influenza. However, wheezing may be heard if the influenza has led to bronchiolitis. Wheezing is caused by an obstruction of the bronchioles that may be due to bronchiolitis, asthma, cystic fibrosis, or chronic lung disease.
