What does IV stand for in medical terminology?

In medical terminology, IV stands for intravenous infusion, which refers to the delivery of fluids, medications, or nutrients directly into a patient’s bloodstream through a vein. This method is essential in various medical scenarios, including administering medications quickly, providing hydration, or delivering blood products. The term "intravenous" specifically indicates that the administration occurs within a vein, and "infusion" denotes the process of introducing a substance into the body slowly over time. This is a critical concept in clinical settings and is commonly encountered in nursing, emergency care, and various treatments, highlighting its importance in patient care and treatment protocols.
