A nurse who provides IV infusion therapy is a healthcare professional trained to administer medications, fluids, and other treatments directly into a patient's bloodstream through an intravenous (IV) line. They carefully monitor the patient's condition, assess for any adverse reactions, and adjust the infusion rate as needed to ensure safe and effective delivery of the treatment. These nurses play a crucial role in various medical settings, such as hospitals, clinics, and home care, contributing to patient comfort, recovery, and overall well-being.
