What is a common complication associated with excessive IV fluid administration?

Fluid overload is a common complication that arises from excessive intravenous (IV) fluid administration. When a patient receives more fluid than their body can handle, it can lead to conditions such as edema (swelling due to excess fluid in body tissues), hypertension (increased blood pressure), and even heart failure in severe cases. The body's natural ability to balance fluid levels can be overwhelmed, resulting in the accumulation of fluid in the lungs, which can cause respiratory distress, and in other tissues throughout the body.

In an IV setting, careful monitoring of the patient's fluid intake and output, as well as regular assessment of their clinical status, is vital to prevent fluid overload. While other complications such as infection, allergic reactions, and electrolyte imbalances can also occur, fluid overload specifically relates to the volume of fluid administered rather than a direct response to it or individual patient sensitivities. Therefore, this makes fluid overload the most relevant answer in the context of the question.
