Which method is NOT a form of administration for medications mentioned?

  1. Direct application

  2. Iontophoresis

  3. Oral ingestion

  4. Phonophoresis

The correct answer is: Oral ingestion

The other options, direct application, iontophoresis, and phonophoresis, are all forms of administering medications to the body. However, oral ingestion involves swallowing medication, whereas the other options involve applying medication directly to the body or using electrical or sound waves to help the medication penetrate the skin. Therefore, oral ingestion is the only option that is not a form of administration mentioned.
