What is the primary function of an Infusion Pump?

• A. Infusion Pump
• B. Syringe Pump
• C. PCA Pump
• D. Dialysis Machine

Answer: (A)

Infusion pumps are used to deliver prescribed fluids, medications, or nutrients into a patient’s bloodstream through an IV line at a precisely controlled rate and volume. This automated control ensures the patient receives the exact dose over the designated time, reducing manual errors and enabling therapies like antibiotics, chemotherapy, hydration, or nutrition to be administered safely.

A syringe pump is a type of infusion pump that uses a syringe to deliver very small, precise volumes, but its overall purpose is still to infuse medications or fluids—just on a different scale. A PCA pump is a specialized infusion pump that allows the patient to self-administer a pre-programmed dose of analgesia under safeguards, which is a particular use of infusion technology. A dialysis machine, by contrast, removes waste and excess fluids from the blood rather than delivering therapeutic infusions.
