Answer to Question 1

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 (GI) manifestation of CF, and a chest radiograph showing patchy atelectasis and obstructive emphysema indicates CF. Gastric contents contain hydrochloride normally; it is not diagnostic. Bronchoscopy and duodenal fluid are not diagnostic. Stool test for trypsin and intestinal biopsy are not helpful in diagnosing CF.

Answer to Question 2

ANS: D
Short-acting 2 agonists are the first treatment in an acute asthma exacerbation. Ephedrine is not helpful in acute asthma exacerbations. Theophylline is unnecessary for treating asthma exacerbations. Aminophylline is not helpful for acute asthma exacerbation.
