Question

The chief mechanism for maintaining fluid balance is to
A) adjust fluid intake so it equals fluid output
B) adjust fluid intake so it is slightly above fluid output
C) adjust fluid output so it equals fluid input
D) none of the above

Accepted Answer

The most important mechanism for maintaining fluid balance is by adjusting fluid output (urine, sweat, breathing) so that it equals fluid input (liquids and foods consumed). This is essential to prevent both dehydration and water overload. While adjusting fluid intake above fluid output may temporarily increase fluid balance, it is not sustainable in the long run and may lead to water intoxication.
