Which abbreviation is used to indicate a rectal administration route?

• A. Per rectum
• B. Rectal route
• C. Post-rectal
• D. Rectum or rectal route

Answer: (D)

Abbreviations for how a drug is given should be clear about where and how it enters the body. For rectal administration, naming the site explicitly helps avoid confusion. Rectum or rectal route achieves this by directly indicating the anatomical site (rectum) and the route (rectal), making it the clearest and least ambiguous label among the options. The other phrases either describe the method without naming the site, aren’t standard abbreviations, or aren’t used to label the route.
