How often should medication prescribed as "q2h" be administered?

• A. Every hour
• B. Every two hours
• C. Every four hours
• D. Daily

Answer: (B)

Medications prescribed as "q2h" are intended to be administered every two hours. The abbreviation "q" stands for "quaque," which is Latin for "every," and the number following it specifies the interval in hours. Therefore, when a prescription states "q2h," it directs healthcare providers to give the medication at two-hour intervals throughout the day. This ensures that the medication maintains its intended therapeutic effect by providing consistent levels in the bloodstream. Recognizing such abbreviations is crucial in medication administration to avoid errors and ensure patient safety.
