Which abbreviation represents twice daily?

• A. bid, b.i.d
• B. tid
• C. qid
• D. qd

Answer: (A)

In medication orders, frequency is shown by standard abbreviations. The one for two times per day is bid, short for bis in die, meaning you give the dose twice a day (roughly every 12 hours). The other options correspond to different frequencies: tid means three times daily; qid means four times daily; qd means once daily (every day). Understanding these helps ensure medications are given at the correct intervals for safety and effectiveness.
