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.

Explanation
A. Intellectual capability: Intellectual ability generally remains intact with age, unless affected by disease such as dementia.
B. Tolerance for extremes in temperature: Decreases due to impaired thermoregulation and thinner skin.
C. Total body water: Decreases, making older adults more susceptible to dehydration and electrolyte imbalances.
D. Force of pulse: May decrease due to decreased cardiac output and vascular elasticity.
E. Pulmonary gas exchange: Decreases due to changes in alveolar surface area and chest wall compliance.
F. Conduction speed of CNS impulses: Decreases, leading to slower reaction times and reflexes.
Correct Answer is D
Explanation
A. Decision making skills
Decision-making often remains intact with age unless cognitive impairment is present.
B. Cognitive capacity
Normal aging does not significantly impair cognition; changes are usually subtle and not generalized.
C. Creative ability
Creativity often remains strong into older age and may even increase with experience.
D. Short-term memory
This is a common and expected change with normal aging. Older adults may take longer to learn new information or recall recent events.
