The answer is D. All of the Above.
BID, TID, and QID are terms used by doctors for prescribing medicines. BID in Latin stands for <em>bis in die</em>, which means twice a day. When the doctor prescribes a drug with BID priority, it means that the nurse should give it twice, normally with a 12-hour interval. TID stands for <em>ter in die</em>. This means it should be administered three times a day. If this is the prescription of the doctor, the medicine should be given three times within 24 hours. This is within an 8-hour interval. Lastly is QID. In Latin, this means <em>quater in die</em> which means four times a day. Usually, this has a 6-hour interval.
