Answer to Question 1

ANS: B
Cumulative effects are related to diminished metabolism or excretion of a drug that causes it to accumulate. Cumulative effects can lead to drug toxicity. Toxicity occurs when adverse effects are severe. Inability to control the ingestion of drugs is drug dependence. The need for higher dosage to produce the same effect as previous lower dosages is the definition of tolerance.

Answer to Question 2

ANS: A
Males' stomachs empty more rapidly; children have increased motility, resulting in decreased absorption time. As one gets older, gastrointestinal (GI) motility is decreased, allowing for increased absorption time; women have slower gastric emptying, resulting in more time for absorption. Males' stomachs empty more rapidly; however, as one gets older, GI motility is decreased, resulting in an increase in absorption time. As one gets older, GI motility is decreased, allowing for increased absorption time; women have slower gastric emptying, resulting in more time for absorption.
