What type of administration route is NOT typically classified as enteral?

The intravenous route is not classified as enteral because it does not involve the gastrointestinal (GI) tract at all. Enteral administration refers to any method of delivering medication that utilizes the digestive system, such as oral, rectal, or through a nasogastric (NG) tube. These methods involve the absorption of medication as it passes through the GI tract.

In contrast, the intravenous route directly delivers medication into the bloodstream, completely bypassing the digestive system. This allows for immediate effects and is often used in situations where rapid action is needed or when the patient cannot take medications orally. The specificity of enteral routes relates to their dependence on gastrointestinal absorption, which is not relevant to the intravenous method.
