Feedback
A Although the medication is being given at 4-hour intervals, it is not being given every 4 hours. If it were given every 4 hours, it could be given six times in 24 hours, not three, as with TID administration.
B "Twice a day" is the meaning of "BID." The patient is receiving the medication three times a day.
C The medication is being given three times a day at 4-hour intervals. The medication the nurse is documenting is diazepam, 5 mg orally TID.
D The medication administration is not spaced apart as every 8 hours.
