What does the abbreviation 'sq' indicate?

The abbreviation 'sq' stands for 'subcutaneous,' which refers to the administration of medications under the skin, typically into the fatty layer of tissue. This route is commonly used for insulin injections or certain vaccines, as it allows for a slower absorption of the medication into the bloodstream compared to other methods like intravenous or intramuscular injections.

Subcutaneous injections are usually administered at a 45-degree angle, depending on the patient's body composition, and are often preferred for self-administration because they can be easily performed in an outpatient setting. Understanding this abbreviation is crucial for medication technicians, as it informs them about the correct technique and site for administering various medications while ensuring patient safety and efficacy of treatment.
