What is the meaning of the abbreviation QID?

The abbreviation QID stands for "quater in die," which is a Latin term meaning "four times a day." This term is commonly used in medical prescriptions and caregiver notes to indicate the frequency with which a medication or treatment should be administered. Understanding this abbreviation is crucial for caregivers, as it helps ensure that patients receive their medications at the correct intervals for optimal effectiveness and safety.

In contrast, the other choices represent different medical instructions but do not align with the meaning of QID. For instance, “every other day” describes a less frequent schedule, while “temperature” refers to a specific measurement rather than a dosing frequency. The last option concerning “subcutaneous” refers to a method of administering medication rather than a dosing schedule. Thus, knowing that QID specifically indicates a four times daily frequency is vital in caregiving for proper medication management.
