When a medication is administered via the rectum, what abbreviation is used?

The abbreviation used for medication administered via the rectum is "pr," which stands for "per rectum." This term is commonly used in medical contexts to indicate that a treatment or medication is to be given rectally.

Using this abbreviation helps healthcare providers communicate effectively about the route of administration, ensuring that the medication is given correctly and safely. It is important in medical practice to be precise with abbreviations to avoid any potential confusion regarding how a medication should be administered.

The other options refer to different routes or methods of medication. For instance, "SL" indicates sublingual administration (under the tongue), "AD" refers to the right ear (auris dextra), and "AU" means both ears (auris utraque). Understanding these distinctions is essential for accurate medication administration and patient care.
