What does the abbreviation "IV" signify in medical terminology?

The abbreviation "IV" in medical terminology signifies "intravenous." This term refers to the administration of substances directly into a person's vein. Intravenous therapy is commonly used for delivering fluids, medications, and nutrients directly into the circulatory system, allowing for rapid absorption and effectiveness. This method is particularly critical in emergency situations or when a patient requires immediate medication action, as it bypasses the digestive system and ensures that the therapeutic agents enter the bloodstream directly. Understanding this abbreviation is essential for medication aides and healthcare providers, as they frequently encounter IV administration in clinical settings.
