What is the primary purpose of intravenous (IV) therapy?

The primary purpose of intravenous (IV) therapy is to deliver fluids, medications, and nutrients directly into the bloodstream. This method allows for rapid absorption and immediate effect of substances introduced into the circulatory system. It is invaluable in medical settings because it provides a means to efficiently manage hydration, administer pharmaceuticals, and deliver essential nutrients, especially in patients unable to take oral medications or face severe conditions requiring quick intervention.

While administering blood transfusions is an important aspect of IV therapy, it is merely one application of the broader purpose of IV therapy, which encompasses a variety of treatments beyond blood products. Analyzing blood components pertains more to laboratory procedures that do not involve administering therapy and monitoring vital signs is a critical assessment activity but does not directly relate to the primary function of IV therapy itself.
