What is hypervolemia?

Hypervolemia refers to a condition where there is an excess of fluid in the body, specifically an increase in the volume of blood plasma. This can occur due to various factors such as excessive fluid intake, impaired kidney function, or heart failure, resulting in fluid retention.

The correct answer highlights that fluid accumulates without a loss of fluid, emphasizing that hypervolemia is characterized by an overall increase in body fluid levels rather than a deficit. This excess volume can put strain on the cardiovascular system and can lead to complications if not managed properly.

In contrast, the other options discuss situations involving fluid deficits or movement rather than accumulation. These scenarios do not pertain directly to the definition of hypervolemia, which centers on the presence of too much fluid in the body rather than too little or the movement of fluid between compartments.
