Answer to Question 1

ANS: 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

ANS: C
Clozapine can cause agranulocytosis. If the absolute neutrophil count (ANC) drops below 1000/mcL, the drug must be discontinued permanently. Blood counts must be evaluated weekly, and this evaluation should be continued for several weeks after withdrawal of the drug. Fever, sore throat, and mouth ulcers are symptoms of agranulocytosis and should be reported immediately.
