Which term indicates that a medication should be taken four times a day?

  1. Qd

  2. Bid

  3. Tid

  4. Qid

The correct answer is: Qid

The term that indicates a medication should be taken four times a day is indeed "Qid," which stands for "quater in die" in Latin. This phrase translates to "four times a day." It is commonly used in medical prescriptions to ensure that patients understand how often they need to take their medication to maintain effective therapeutic levels. The other options represent different dosing frequencies: "Qd" means once a day, "Bid" means twice a day, and "Tid" means three times a day. Each of these terms is designed to provide specific instructions for medication administration, highlighting the importance of understanding these abbreviations for proper patient care and adherence to prescribed regimens.
