If a prescription states QID, how often should the medication be given?

• A. Twice a day
• B. Three times a day
• C. Four times a day
• D. Every other day

Answer: (C)

The abbreviation QID stands for "quater in die," which is Latin for "four times a day." When a prescription indicates QID, it instructs that the medication should be administered four times throughout the day. This dosing schedule is typically evenly spaced to maintain consistent therapeutic levels in the patient’s system. Understanding such abbreviations is crucial for ensuring proper medication administration and adherence to the prescribed treatment plan, which ultimately impacts the effectiveness of the therapy.
