qd stands for?

qd stands for?

• A. Once a day
• B. Twice a day
• C. Four times a day
• D. Nothing by mouth

Answer: (A)

qd comes from the Latin quaque die, meaning once per day. It’s used on prescriptions to indicate that a dose should be taken daily. The other options reflect different instructions: twice a day is usually written as bid or bis in die; four times a day is qid; nothing by mouth is NPO. Because qd explicitly means once daily, it’s the best match for this abbreviation. Some settings avoid qd due to potential misreading, but the standard meaning remains daily dosing.
