What does the abbreviation q.h. indicate in dosing schedules?

• A. Every hour
• B. Every day
• C. Every 4 hours
• D. Every 6 hours

Answer: (A)

The main idea here is how dosing frequencies are written in prescriptions. The abbreviation q.h. uses a q for “every” and h for “hour,” from the Latin hora. So q.h. means every hour. This is different from other common timings like q.d. (every day), q4h (every 4 hours), or q6h (every 6 hours). In practice, you’d administer that medication once each hour around the clock unless the directive specifies otherwise.
