Answer to Question 1

ANS: C
Adverse drug reactions are seven times more common in the elderly than in younger adults and may contribute to an increased risk for drug interactions, toxicity, and falls.
Mobility may decline in the elderly, increasing the risk for falls; however, this option ignores the link between falls and medication use in the elderly.
Inappropriate use of prescription drugs is a concern, but it is not the best reasoning for an increased risk for falls in the elderly.
Rapid drug excretion should not contribute to an increased risk for falls in the elderly.

Answer to Question 2

ANS: B
The interval between doses of the medication should be increased in older adult patients, because drugs that undergo the first-pass effect may not be broken down as well as in someone with full liver function.
A higher dose of the medication is not indicated, because toxic effects could occur.
A change in administration may be indicated in the older adult, because metabolism is affected in the elderly.
The interval between doses should not be decreased, but increased.
