Answer to Question 1

ANS: A
Acetylcysteine is used as an antidote for acetaminophen overdose if given within 12 to 24 hours of ingestion. Dornase alfa is used to treat cystic fibrosis. Gastric lavage is no longer used as treatment. Liver enzyme tests are indicated since acetaminophen is hepatotoxic.

Answer to Question 2

ANS: A
Inhaled medications have more immediate effects than oral preparations. As long as they are used correctly, systemic side effects are less common. Less drug is needed for therapeutic effects, since the drug is delivered directly to target tissues. Increased doses will lead to drug tolerance.
