Question

Total body water in older adults is:

A. Increased because of decreased adipose tissue and decreased bone mass.
B. Increased because of decreased renal function and hormonal fluctuations.
C. Decreased because of increased adipose tissue and decreased muscle mass.
D. Decreased because of renal changes that cause diuresis with sodium excretion.

Answer 1

Total body water in older adults is decreased because of increased adipose tissue and decreased muscle mass.

Step-by-step explanation:

In older adults, the total body water is decreased because of increased adipose tissue and decreased muscle mass.

The proportion of body water changes with development, and the body water percentage in older adults can be as low as 45 per cent. This is due to the increased accumulation of adipose tissue (fat) and decreased muscle mass as individuals age.

It is important to note that dehydration and fluid depletion can also affect total body water, leading to imbalances in blood pressure and hormone regulation.
