Answer to Question 1

ANS: B
Bronchodilators should be given before CPT to open bronchi and make expectoration easier. These medications are not helpful when used after CPT. Oxygen is administered only in acute episodes, with caution, because of chronic carbon dioxide retention.

Answer to Question 2

ANS: A
A sweat test result of greater than 60 mEq/L is diagnostic of CF, a high level of fecal fat is a gastrointestinal manifestation of CF, and a chest radiograph showing patchy atelectasis and obstructive emphysema indicates CF. Bronchoscopy, duodenal fluid analysis, stool tests for trypsin, and intestinal biopsy are not helpful in diagnosing CF. Gastric contents normally contain hydrochloride; it is not diagnostic.
