What does the abbreviation "IV" represent in nursing?

The abbreviation "IV" stands for "Intravenous." This term is commonly used in nursing and healthcare to refer to the administration of fluids, medications, or nutrients directly into a patient's bloodstream through a vein. Intravenous therapy is a crucial method in medical settings, as it allows for rapid administration of treatments, which can be vital in acute care situations. By delivering medications directly into circulation, this method ensures immediate availability and effect, making it an essential practice for hydration, electrolyte balance, and the delivery of life-saving medications.

In contrast, the other terms listed have different meanings: "Intramuscular" refers to injection into the muscle, "Intradermal" involves administering medications into the dermis or under the skin, and "Gastrostomy" pertains to a surgically created opening into the stomach for feeding. Understanding these distinctions is key to effective patient care.
