Infusion therapy nurses are registered nurses (RNs) who specialize in giving patients medicine and fluids through intravenous (IV) needles and catheters. Infusion therapy nurses maintain fluid tubes and bags, monitor the patient, and watch for dangerous drug interactions. Close monitoring of the treatment equipment is essential to avoid complications such as phlebitis (inflammation of the vein) or central line-associated bloodstream (CLAB) infections. Infusion therapy nurses need excellent communication skills to explain the treatment to patients and ease any anxiety they may have, as well as to collaborate with the medical team serving the patients.
