Answer to Question 1

A
Because of the obstructive lung problems associated with cystic fibrosis, the FVC will be decreased, not increased. Obstruction will lead to all expiratory flows being low. Air trapping will cause the RV to be increased.

Answer to Question 2

C
It is possible for the initial chest radiograph to show normal lung fields. But if significant amounts of water were inhaled, the radiograph may show areas of atelectasis or pulmonary edema. These later changes may occur within the first 48 to 72 hours after the incident.
