What does q.d. indicate?

• A. Every day
• B. Daily
• C. Everyday
• D. Once per day

Answer: (C)

Understanding how dosing frequency is expressed in medical abbreviations. q.d. comes from the Latin quaque die, meaning the medication should be given every day, i.e., once in 24 hours. That makes “every day” or the synonym “daily” the correct translations. The single word “everyday” is not correct here because it’s an adjective meaning ordinary or routine, not a time interval. So the intended meaning is “every day” or “daily.”
