Which route refers to administering medications to areas such as skin, eyes, ears, nose, lungs, rectum, or vagina?

• A. Oral route
• B. Buccal route
• C. Topical route
• D. Inhalation route

Answer: (C)

The main idea here is that the topical route refers to applying medications to the body's external surfaces or mucous membranes. That includes the skin as well as areas like the eyes, ears, nose, and the mucous membranes of the rectum or vagina. The goal is typically a local effect at the site of application, though some absorption into the bloodstream can occur.

So, administering meds to those specific areas—skin, eyes, ears, nose, rectum, and vagina—fits the topical route because the drug is applied directly to an external surface or mucous membrane rather than swallowed or inhaled. The other routes involve different pathways: swallowing for the oral route, placement inside the mouth for the buccal route, and breathing in for the inhalation route, which targets the lungs.
