Per rectum is abbreviated as which term?

Per rectum is abbreviated as which term?

• A. per rectum
• B. p.r.
• C. PR
• D. rectal

Answer: (B)

Medical shorthand for routes of administration is used to keep orders concise. For the rectal route, the conventional abbreviation is p.r. with periods. This form comes from the Latin phrase per rectum and has been used to reduce ambiguity in handwritten or fast-moving clinical settings. Using lowercase letters with periods helps minimize misreading compared with the uppercase form PR, which can be mistaken for other terms like pulse rate or public relations. Therefore, p.r. is the most clear and traditionally preferred way to denote per rectum.
