Homonym: IV (Four)
"IV" stands for "intravenous," which refers to a method of delivering fluids, medications, or nutrients directly into a person's bloodstream through a vein. This technique is commonly used in hospitals to provide quick treatment, especially in emergencies. For example, doctors may use IVs to hydrate patients or administer antibiotics to fight infections.
An IV setup typically includes a bag of fluid, a tube, and a needle that is inserted into a vein, often in the arm. This method allows for precise control over the dosage and speed of delivery, making it an essential tool in modern medicine.
