Which of the following medication routes does a medical assistant administer topically?

The subcutaneous route involves injecting medication into the fatty tissue just beneath the skin, which does not qualify as topical administration. This method is used for medications that require absorption into the bloodstream, rather than local effects on the skin surface.

The intramuscular route involves injecting medication directly into a muscle, which is not considered topical administration. This method is used for medications that require rapid absorption into the bloodstream and is typically used for vaccines and certain medications that cannot be taken orally.

While the term percutaneous refers to medication administered through the skin, it primarily encompasses methods involving needles or punctures rather than topical applications. This route is not synonymous with topical administration, which specifically refers to applications that do not involve penetration beyond the skin's surface.
