Answer to Question 1

ANS: C
Promethazine can cause severe respiratory depression, especially in very young patients; it is contraindicated in children younger than 2 years. The medication should not be given as ordered. It is not safe to give the drug and then monitor for bronchoconstriction . The drug is not safe in this age group when given orally.

Answer to Question 2

ANS: C
Promethazine can cause severe local tissue injury if it extravasates into tissues, so the medication should be administered in an IV that is flowing freely through a large-bore needle. The drug should be administered at a rate of 25 mg/min or less. Dimenhydrinate is indicated for motion sickness, not postoperative N/V. Cardiac dysrhythmias were a concern with two antihistamines no longer on the market, astemizole and terfenadine.
