What meaning does the abbreviation "pr" have?

The abbreviation "pr" stands for "per rectum," which indicates that a medication is to be administered rectally. This route of administration is commonly used for medications intended for systemic effects or for local treatment of the rectal area.

Understanding abbreviations like "pr" is essential for pharmacy technicians and other healthcare professionals to ensure accurate medication administration and communication with patients and other members of the healthcare team. The rectal route can be particularly beneficial when other routes (such as oral) are not suitable due to nausea, vomiting, or in situations where the patient is unable to take medications by mouth.

In contrast, options like buccal, intrathecal, and both eyes refer to different methods of drug administration that do not relate to the rectal route. Thus, the choice of "B" aligns perfectly with the recognized medical terminology associated with "pr."
