IV fluid therapy is often indicated when there are symptoms of dehydration. Dehydration can manifest through various signs such as dry mucous membranes, decreased skin turgor, increased thirst, and diminished urine output. In some cases, dehydration can lead to more severe complications, which underscore the need for prompt intervention, such as administering IV fluids to restore hydration levels effectively and quickly.

In contrast, while excessive sweating can lead to fluid loss, it does not inherently mean that IV therapy is required; often, oral rehydration may suffice. Severe headache can indicate many potential issues, and while dehydration can contribute to headaches, it is not a definitive indicator for IV therapy on its own. A positive fluid balance suggests that fluid intake exceeds output, which would not necessitate fluid administration; instead, it may even indicate the opposite need.
