What is the meaning of the abbreviation SQ?

The abbreviation "SQ" stands for "Subcutaneous," which refers specifically to the layer of fat and connective tissue that lies just beneath the skin. This term is commonly used in medical contexts, especially when discussing injections or placements of medications that are administered into the subcutaneous tissue.

Using "SQ" indicates that a substance, such as medication or vaccine, is injected into this layer, allowing for slower absorption into the bloodstream compared to intravenous administration. Understanding this terminology is crucial for caregivers, as it informs them of the appropriate routes of administration for medications and helps ensure the safe handling of treatments for individuals in assisted living care.

Other options provided do not accurately reflect the meaning of "SQ." For example, the telephone order refers to a method of communication regarding medical orders, while temperature represents a vital sign, and the term "every four hours" is often abbreviated as "Q4H" or similar. Recognizing the specific medical terminology is essential for effective and safe caregiving practices.
