Answer to Question 1

C
Risperidone given intramuscularly is a depot preparation used for long-term therapy. Significant release of the drug does not occur until 2 to 3 weeks after injection; therefore, patients must take an oral antipsychotic medication until drug levels are raised. Therapeutic levels are reached 4 to 6 weeks after injection. Patients need injections every 2 weeks. With IM dosing, the incidence of extrapyramidal symptoms is substantial.

Answer to Question 2

B
Drug absorption through the skin is more rapid in infants, because their skin is thinner and has greater blood flow; therefore, infants are at increased risk of toxicity from topical drugs. Because of increased drug absorption through the skin, infants should not be given additional drugs via other routes. If a drug is more likely to be absorbed rapidly, it will have more side effects.
