Registered Practical Nurse (RPN) Practice Test

Which of the following is a focus of nursing assessment for older adults regarding medication?

1. Vitamin interactions

2. Absorption rates

3. Cognitive function

4. Physical activity levels

The correct answer is: Absorption rates

In the context of nursing assessment for older adults regarding medication, focusing on absorption rates is essential due to the physiological changes that occur with aging. As individuals grow older, the body's ability to absorb, distribute, metabolize, and excrete medications can significantly change. Older adults often have decreased gastric pH, slowed gastric emptying, and changes in gut motility, all of which can affect how medications are absorbed. For instance, a medication that is best absorbed in an acidic environment might be less effective if the gastric pH is elevated. Additionally, older adults may also have changes in skin integrity and decreased blood flow, affecting transdermal drug delivery and absorption. When assessing medication regimens in older adults, nurses need to be particularly vigilant about these altered pharmacokinetics to avoid potential underdosing or overdosing which can lead to ineffective treatment or adverse effects. By understanding these factors, nurses can collaborate effectively with healthcare providers to manage medications safely and optimize therapeutic outcomes for older patients.
