Which of the following statements is NOT true regarding IV infusion pumps?

An IV infusion pump is a medical device designed to deliver fluids, such as medications and nutrients, directly into a patient's circulatory system in a controlled manner. The statement indicating that a physician order is required to use an IV infusion pump is not true in the context provided. While protocols and hospital policies often necessitate a physician's order for the administration of specific medications or treatments, the operation of the pump itself can be carried out by trained nursing staff or clinicians following established guidelines.

The other statements are accurate representations of the functions and benefits of IV infusion pumps. They are designed to provide precise control over the flow rates of IV fluids, ensuring that patients receive their medications and fluids at the correct dosages. This precision helps minimize the risk of administering incorrect doses, which is crucial in preventing medication errors. Additionally, IV infusion pumps are versatile; they can accommodate both large volume infusions (such as fluids for hydration or nutrition) and small volume infusions (like concentrated medications), making them suitable for a wide range of clinical scenarios.
