What does the term 'per' indicate in medication directions?

The term 'per' in medication directions indicates the method or route by which a medication is to be administered, which aligns with the concept of "by" or "through." This is essential for ensuring that the medication is taken in the correct manner, as it helps clarify how the drug should be delivered to achieve the desired therapeutic effect. Understanding this terminology is crucial for medication aides, as misinterpretation of routes can lead to improper administration, potentially resulting in ineffective treatment or adverse effects.

While the other options may seem relevant in different contexts, they do not accurately capture the specific meaning of 'per' in relation to medication administration. Recognizing the significance of precise terminology in medication directions is vital for patient safety and effective care.
