Final answer:
Managing fluid balance improves cardiac output and reduces workload on the heart.
Step-by-step explanation:
Managing fluid balance can improve cardiac output and reduce workload on the heart.
When there is an imbalance in fluid levels, such as dehydration or excessive fluid intake, it can affect the volume of blood pumped by the heart and increase the workload on the heart.
By maintaining proper fluid balance, the volume of blood in the body is optimized, which allows the heart to pump blood more efficiently, resulting in improved cardiac output and reduced workload on the heart.
