Answer to Question 1

ANS: B
The drug epinephrine is given in the case of anaphylaxis because it is a quick-acting drug that produces bronchodilation and vasoconstriction, which relieves respiratory distress. The drug can be ordered to be repeated every 20 minutes. The patient may experience an increase in heart rate.

Answer to Question 2

ANS: D
Allegra does not induce drowsiness as does Benadryl.
