A decrease in number of nephrons does not affect renal function initially,but over time the older adult patient loses renal reserve,and the aging kidney is unable to concentrate urine,excrete hydrogen,or maintain sodium/potassium balance.Additionally,the elderly are at high risk for dehydration and are more vulnerable to injury from decreases in renal blood flow such as episodes of hypotension leading to acute kidney injury (AKI)or from extreme changes in body fluid composition and acid-base balance.
