Enteral administration of a drug refers to which of the following?

• A. The primary effect
• B. The site of action
• C. The route of administration
• D. The bioavailability

Answer: (C)

Enteral administration refers to delivering a drug through the gastrointestinal tract, i.e., the route by which the drug is given (such as by mouth or via a tube into the stomach or intestines). It’s about how the drug enters the body, not what it does (the primary effect), where it acts (the site of action), or how much reaches the bloodstream (bioavailability). This contrasts with routes outside the GI tract, like injections or inhalation. So enteral administration is best understood as the route of administration through the digestive tract.
