Intravenous administration is a common method of delivering medications, fluids, and nutrients directly into the bloodstream through a vein. This route of administration allows for rapid and efficient absorption of the administered substances, making it especially useful for emergency situations or when a patient is unable to take medications orally. Intravenous administration is commonly used in hospitals, clinics, and other healthcare settings for a wide range of purposes, including delivering antibiotics, pain medications, chemotherapy drugs, and fluids for hydration. It is performed by trained healthcare professionals and requires the use of specialized equipment, such as IV catheters, infusion pumps, and IV bags. Overall, intravenous administration is an important and versatile method of delivering necessary treatments to patients.
