What does QID indicate in medication administration?

• A. Every eight hours.
• B. Four times a day.
• C. Twice daily.
• D. Once daily.

Answer: (B)

QID indicates four times a day. It comes from the Latin quater in die, meaning the total daily dose is divided into four administrations. In practice, this is typically spaced roughly every 6 hours to distribute the dose across a 24-hour period. This differs from other common abbreviations: BID means twice daily, tid means three times daily, and qd means once daily. So, a QID order requires four doses within each day.
