Answer to Question 1

ANS: B
Tricyclic antidepressants block neurotransmitter uptake, increasing the amounts of norepi-nephrine and serotonin available. Decreasing dopamine is the action of typical antipsychotic medication. Increasing monoamine oxidase is not the action of tricyclics. Benzodiazepines, not tricyclics, increase the effects of GABA.

Answer to Question 2

ANS: B
Haloperidol decanoate is a depot medication, given intramuscularly every 2 to 4 weeks. It is unknown whether the patient has a support system. The patient probably received education, including written instructions prior to discharge. Changing to another classification of medi-cation would not necessarily improve compliance.
