Answer to Question 1

ANS: A, B, C, D
Dystonic reactions, pseudoparkinsonism, tardive dyskinesia, and akathisia are extrapyramidal symptoms of antipsychotic agents. Antipsychotic drug therapy often causes substantial weight gain, but this is not classified as an extrapyramidal adverse effect.

Answer to Question 2

ANS: C
Low and high potency refers only to the milligram doses used for the medications and does not suggest any difference in effectiveness. Potency is not related to severity of adverse effects or onset of action. Potency does not refer to effectiveness.
