What does SL stand for in medication administration?

In the context of medication administration, SL stands for sublingual administration. This method involves placing a medication under the tongue, where it dissolves and is absorbed directly into the bloodstream through the tissues there. This route is preferred for certain medications because it allows for rapid onset of action, bypasses the gastrointestinal tract, and may avoid first-pass metabolism in the liver.

Understanding the specific terminology used in medication administration is essential for safe and effective practice. The other terms listed refer to different concepts: the first pertains to ear-related instructions, the second indicates a restriction on oral intake, and the last refers to the frequency of medication usage. Each term carries significant implications for patient care, underscoring the importance of being familiar with medical abbreviations and their meanings.
