QID stands for four times a day.

QID stands for four times a day.

• A. Autoclave
• B. BID
• C. QID
• D. Wave scheduling

Answer: (C)

Dosing frequency abbreviations tell you how often to take a medication. QID means four times a day, from Latin quater in die, literally “four times in a day.” So when a prescription uses QID, the dose should be taken four times within a 24-hour period as directed. The other terms here aren’t about dosing frequency: an autoclave is equipment used to sterilize instruments, and wave scheduling is a method for arranging patient appointments. A related shorthand, BID, stands for twice daily, which helps explain how these abbreviations encode timing in prescriptions.
