A nurse is caring for an older adult client.
The client has an increased risk for dehydration due to which of the following physiological changes that can occur with aging?
Decrease in systolic blood pressure
Increase in saliva production
Increase in percentage of body water
Decrease in kidney function
Decrease in kidney function
The Correct Answer is D
Choice A rationale
A decrease in systolic blood pressure is not a physiological change that increases the risk of dehydration in older adults.
Choice B rationale
An increase in saliva production does not occur with aging and does not increase the risk of dehydration.
Choice C rationale
An increase in the percentage of body water does not occur with aging. In fact, total body water decreases with age, which can contribute to an increased risk of dehydration.
Choice D rationale
A decrease in kidney function is a common physiological change that occurs with aging. This can lead to a decreased ability to concentrate urine and conserve water, increasing the risk of dehydration.
