What is the significance of the abbreviation 'SQ' in medication administration?

The abbreviation 'SQ' stands for 'subcutaneous,' which is a specific route of administration for delivering medication. When medication is administered subcutaneously, it is injected into the layer of fat and tissue just beneath the skin rather than directly into the muscle or the bloodstream. This route is significant because it influences how the medication is absorbed, its onset of action, and its overall effectiveness. Subcutaneous injections are commonly used for medications that require a slow, steady absorption into the bloodstream, such as insulin or certain vaccines. Understanding the abbreviation 'SQ' is essential for medication aides to ensure proper administration and to communicate effectively with healthcare professionals about how medications should be given.
