Which renal change is found in older adults?
a. Sharp decline in glomerular filtration rate
b. Sharp decline in renal blood flow
c. Decrease in the number of nephrons
d. Decrease in urine output
Correct answer: c. Decrease in the number of nephrons
Explanation:
In older adults, there is a decrease in the number of nephrons, which contributes to a gradual decline in kidney function, including a reduction in glomerular filtration rate (GFR) and renal blood flow. However, urine output typically remains stable unless there is a significant underlying condition.
