Which of the following is NOT a common form of oral medication?

The correct answer identifies that powder is not commonly considered a direct form of oral medication like the others listed. While powders can be a way to deliver medication (for example, mixing a powder with liquid), they are not typically categorized as a standalone form of oral medication that patients would ingest directly.

Liquid forms, tablets, and gel caps, on the other hand, are all standard forms of medication that can be taken orally. Liquid medications are easy to swallow and often used for those who have difficulty with pills. Tablets are solid doses of medication that dissolve in the stomach, while gel caps, which are a form of soft gel, provide an alternative for individuals who prefer or require a different method of ingestion compared to tablets.

Understanding the distinctions between these forms is crucial in medication administration and ensures that patients receive their medications in a manner that is both safe and effective.
