What does the abbreviation PR stand for in medication administration?

The abbreviation PR in medication administration stands for "per rectal." This term is used to indicate that a medication is to be administered through the rectum. Medications given rectally can be necessary for various reasons, such as when a patient is vomiting, unable to swallow, or when a faster onset of action is required. This route of administration allows for absorption of medication directly into the bloodstream, bypassing the digestive system.

Understanding the context and proper usage of abbreviations in medication administration is crucial for healthcare providers. It ensures clear communication and helps avoid medication errors. The other options may sound plausible, but they do not accurately reflect standard abbreviations used in medication administration.
