q.h. denotes dosing interval of what frequency?

• A. Every Minute
• B. Every Day
• C. Every Hour
• D. Every Four Hours

Answer: (C)

q.h. means quaque hora, Latin for every hour. It indicates the dosing interval is hourly—take the dose once each hour. For example, a dose described as 1 tablet q.h. means one tablet every hour, as long as it’s safe to do so. If you see a specific interval like q2h, that would be every two hours, but q.h. alone points to hourly dosing.
