Final answer:
Bladder holding less urine is considered a normal age-related change due to physiological alterations like reduced bladder elasticity in the aging population.
Step-by-step explanation:
The normal age-related change among the options provided is C) Bladder holding less urine. As individuals age, changes occur in the urinary system, such as the bladder's decreased capacity to hold urine, commonly due to physiological alterations like reduced bladder elasticity. It's a common phenomenon that does not necessarily signify a pathological condition but rather a normal part of aging.
Conditions such as dementia and contractures, although they may present in elderly individuals, are not considered normal age-related changes but rather pathologies. Wheezing when breathing can be indicative of respiratory conditions such as asthma or COPD and is also not a standard part of aging. By contrast, benign prostatic hyperplasia (BPH) is a common noncancerous enlargement of the prostate that can impede urine flow, which can contribute to urinary symptoms in older men, yet is a distinguishable condition.
