What is an example of an enteral route of administration?

The enteral route of administration involves delivering substances directly to the gastrointestinal tract, which is essential for digestion and absorption. The oral route is the most common and straightforward example of enteral administration. When medication or nutrients are taken orally, they are ingested and pass through the digestive system where they are absorbed into the bloodstream.

In contrast, the intravenous route involves delivering substances directly into the bloodstream via a vein, bypassing the digestive system entirely, which classifies it as a parenteral route. The intradermal route involves administering substances into the dermal layer of the skin, typically used for allergy testing or vaccinations, and is also considered a parenteral route. The subcutaneous route involves injecting substances into the tissue layer between the skin and the muscle, which similarly does not utilize the gastrointestinal tract for absorption.

Therefore, the oral route is the only example among the choices provided that qualifies as an enteral route of administration, as it directly involves the digestive system for absorption.
