What does 'I.V.' stand for in a healthcare environment?

'I.V.' stands for 'Intravenous,' which refers to the method of delivering medication directly into a patient's bloodstream through a vein. This route is commonly used in healthcare settings for various reasons, such as providing fluids, administering medications, or delivering nutrients rapidly and effectively. By using the intravenous route, healthcare professionals can ensure that the treatment begins to work almost immediately, as it bypasses the digestive system and directly enters the circulatory system.

Other choices, while they may have relevant medical terminology, do not accurately represent the established meaning of 'I.V.' in healthcare. For example, 'Intravitreal' refers to injections into the eye, which is a different context, and 'Induced vascular' or 'Internal variable' do not align with commonly used medical terms related to intravenous therapy. The use of 'Intravenous' captures the critical nature of this specific route of administration in medical practice.
