Certified Clinical Medical Assistant Exam Practice Question

Correct Answer: B

Rationale: Topical administration involves applying medication directly to the skin or mucous membranes. Transdermal (B) is the correct choice, as it refers to delivering medication through the skin for systemic effects, often using patches.

Subcutaneous (A) involves injecting medication into the fatty tissue beneath the skin, not a topical route. Intramuscular (C) refers to injections into muscle tissue, which also does not qualify as topical. Percutaneous (D) generally describes a method of placing instruments through the skin, but it is not specifically a route for topical medication administration.
