Which route involves administration through the rectum?

• A. Oral
• B. Rectal
• C. Vaginal
• D. Intramuscular

Answer: (B)

Rectal administration is the delivery of medication through the rectum, typically using suppositories or enemas. This route is chosen when a patient cannot take medications by mouth (for example, due to vomiting, unconsciousness, or inability to swallow) or when a local effect in the rectal area is needed, while also allowing some degree of systemic absorption. It is distinct from the other routes because it directly involves the rectal canal rather than the mouth, a vaginal passage, or a muscle injection. Therefore, the route that involves administration through the rectum is the rectal route.
