A nurse is collecting data from an older client for signs of dehydration. Which of the following findings should the nurse consider an expected part of the aging process?
Elevation of urine specific gravity
Dry oral mucus membranes
Poor skin turgor over the sternum
Decreased creatine clearance
The Correct Answer is D
A. Elevation of urine specific gravity
This may indicate concentration of urine due to dehydration but is not an expected age-related change.
B. Dry oral mucus membranes
Could suggest dehydration but not an expected normal change; should be evaluated.
C. Poor skin turgor over the sternum
Skin elasticity declines with age, but this makes turgor a less reliable indicator, not necessarily a normal sign of dehydration.
D. Decreased creatinine clearance
Normal with aging due to reduced renal function, even if serum creatinine appears normal due to lower muscle mass.
