Which action helps to ensure patient safety when administering IV fluids by gravity to very young children?

Using a volume-control device for the infusion is essential when administering IV fluids to very young children because it allows for a more precise control over the amount of fluid being delivered. Young children are particularly vulnerable to fluid overload, which can lead to serious complications. A volume-control device helps to mitigate this risk by limiting the volume of fluid that can enter the system at one time. It typically has a chamber that only allows a specific amount of fluid to be infused, which ensures that the child receives the exact prescribed volume without the risk of over-infusion.

Effective management of IV fluids is crucial in pediatric patients, as they require careful consideration of their smaller body size and fluid needs. The use of a volume-control device adds an extra layer of safety during infusion by allowing healthcare providers to maintain a consistent and safe flow rate.
