Answer to Question 1
D
The body system most significantly affected by increased receptor sensitivity in elderly patients is the central nervous system, making this population sensitive to numerous drugs. It is important to evaluate motor and cognitive function before beginning drugs that affect the central nervous system to minimize the risk of falls. Assessment of sleeping patterns is important, but not in relation to patient safety. It is not necessary to evaluate stool patterns or renal function.
Answer to Question 2
A
To promote adherence in elderly patients, selecting the smallest number of medications with the simplest dose regimens is recommended, with once-daily dosing preferred. Instructions should be simplified. Drug dosing should be timed with mealtimes to help patients remember to take them. Lower dosing may be necessary with some drugs, but patients should not do this without consulting their provider.
