Answer to Question 1

D
Feedback:
Only the Caucasian young adult has no indications for administering a smaller than usual dosage. African Americans respond more rapidly to antipsychotic medications and have a greater risk for development of disfiguring adverse effects, such as tardive dyskinesia. Consequently, these patients should be started off at the lowest possible dose and monitored closely. Patients in Asian countries (e.g., India, Turkey, Malaysia, China, Japan, Indonesia) receive lower doses of neuroleptics and lithium to achieve the same therapeutic response as seen in patients in the United States. Arab American patients metabolize antipsychotic medications more slowly than Asian Americans do and may require lower doses to achieve the same therapeutic effects as in Caucasians.

Answer to Question 2

C
Feedback:
A drug is more likely to be effective if the patient thinks it will work than if the patient believes it will not work. This is called the placebo effect. If a drug is taken in successive doses at intervals that are shorter than recommended, or if the body is unable to eliminate a drug properly, the drug can accumulate in the body, leading to toxic levels and adverse effects. This is a cumulative effect. First-pass effect addresses the reduction of available drug when taken orally due to metabolism in the liver before the drug reaches the bloodstream. Cross-tolerance is resistance to drugs within the same class.
