In a medication administration context, what does PR specifically describe?

The term "PR" in a medication administration context stands for "per rectal." This refers to a method of administering medication through the rectum, which is often used when a patient is unable to take medication orally due to vomiting, difficulty swallowing, or other medical conditions.

Understanding this term is crucial for medication aides, as rectal administration can affect the absorption and onset of the medication's effects differently compared to oral administration. It's important to follow specific guidelines and techniques when administering medications this way to ensure safety and effectiveness.

The other options do not accurately reflect the meaning of "PR." While orally administered pertains to medications taken by mouth, prescribed regimen refers to the overall plan regarding a patient's medications, and physical response relates to the body's reaction to treatment or medication, none of them denote the specific administration route that "PR" indicates. Therefore, recognizing "per rectal" is key in the context of medication administration.
