The abbreviation 'qod' is used to indicate which dosing interval?

• A. Every hour
• B. Every other day
• C. Every day
• D. At bedtime

Answer: (B)

The phrase describes a dosing pattern where doses are taken on alternating days. qod means every other day—take a dose, skip a day, then take again on the next day, and so on (for example, Monday, Wednesday, Friday, etc.). This is different from taking a dose every hour or every day, which would be described by other abbreviations, and it isn’t simply a timing instruction like “at bedtime,” which refers to when in the day to take it rather than how often.
