You are caring for a 72-year-old client who has been admitted to your unit for a fluid volume imbalance. You know which of the following is the most common fluid imbalance in older adults?

a. Hypovolemia

b. Dehydration

c. Hypervolemia

d. Fluid volume excess

b. Dehydration

Explanation:

Dehydration is a condition that occurs when there is a shortage of water and other body fluids needed for proper body functions. This can be caused when more fluid is lost from the body compared to the amount of fluid taken in. This leads to fluid imbalance in the body.

As one grows old, physiological changes occur in the body which predisposes an individual to fluid and electrolyte imbalances. Dehydration has been identified as the most common fluid imbalance in older adults as a result of physical disability that restricts older people to access to fluid intake. Other causes such as unmonitored diuretic usage, also play roles.
