What is the role of an IV pump?

The primary function of an IV pump is to regulate the flow rate and volume of IV fluids delivered to a patient. This precision is crucial in maintaining proper fluid balance and ensuring that patients receive the appropriate dosage of IV medications or fluids at the prescribed rates. The pump can be programmed to adjust the flow according to specific patient needs or treatment protocols, providing consistent and accurate delivery.

While some may consider the administration of medications or blood products as part of the pump's function, it is important to note that the pump's primary duty is not solely focused on providing medications or administering blood products. Instead, it facilitates the safe and effective administration of fluids and medications by controlling how much fluid is delivered over time.

Moreover, the IV pump does not monitor vital signs; instead, it is used alongside other monitoring equipment that tracks patient vitals. Its main purpose revolves around the flow management rather than direct patient monitoring or medication delivery without the context of fluid management. Thus, option B accurately captures the essential role of an IV pump in IV therapy.
