Answer to Question 1

C
If IV administration must be done with this drug, it should be given through a large-bore, freely flowing line. The site should be monitored closely for local burning or pain or any sign of extra-vasation, which can cause abscess formation, tissue necrosis, and gangrene requiring amputation. Giving the medication as a rapid IV push or through microbore tubing does not adequately slow the infusion or dilute the drug. Dry mouth and sedation are expected side effects of this drug and are not dangerous.

Answer to Question 2

A
The blood-brain barrier is not fully developed at birth, making infants much more sensitive to CNS drugs than older children and adults. CNS symptoms may include sedation and drowsiness. The first-past effect and GI absorption affect metabolism and absorption of drugs, and renal fil-tration affects elimination of drugs, all of which may alter drug levels.
