Which statement describes oral administration?

Which statement describes oral administration?

• A. Tables, capsules, and liquids taken by mouth
• B. Injected into muscle
• C. Applied to skin
• D. Inhaled as aerosol

Answer: (A)

This question tests route of administration, specifically oral administration. Oral administration means taking medication through the mouth for ingestion, with absorption occurring via the gastrointestinal tract. The forms designed for this route are tablets, capsules, and liquids, all of which are intended to be swallowed. This route is favored for being non-invasive, convenient, and widely used, with dosing and absorption that are well understood for many drugs. The other options describe different routes: injecting into muscle refers to intramuscular or parenteral administration, applying to the skin is topical administration, and inhaling as an aerosol is inhalation. These involve absorption through tissues or the lungs rather than the digestive tract.
