Which term would describe a medication route "PR"?

The term "PR" stands for "per rectum," which is a specific route of administration for medication. Administering medication per rectum allows for the drug to be absorbed through the rectal mucosa. This route is particularly useful in situations where oral administration is not possible, such as when a patient is vomiting, unconscious, or has difficulty swallowing medications.

In addition to its practical advantages, the rectal route can provide rapid absorption of certain medications, making it effective for emergency medications or those that require an immediate therapeutic effect. Understanding this terminology is crucial for healthcare professionals, as it influences not only the method of administration but also the absorption and overall effectiveness of the medication.

The other options do not accurately represent the abbreviation "PR." While pulmonary refers to the lungs, peripheral typically pertains to the outer edges of the body or systems, and parenteral indicates routes of administration other than oral, such as intravenous or intramuscular. However, none of these options align with the specific meaning of "PR."
