The same total number of daily doses is indicated by both abbreviations in which of the following pairs?

The abbreviation "t.i.d." stands for three times daily, indicating a dosing frequency of thrice a day. In contrast, "q6h" denotes a dosing frequency every 6 hours, which results in a total of four doses within a 24-hour period. Thus, these two abbreviations do not represent the same total number of daily doses.

"q.i.d." signifies a dosing frequency of four times daily, indicating a total of four doses in a day. On the other hand, "q8h" implies a dosing frequency every 8 hours, resulting in a total of three doses within a 24-hour period. Therefore, these abbreviations do not indicate the same total number of daily doses.

The abbreviation "q.o.d." refers to a dosing frequency of every other day, meaning the medication is taken once in 48 hours. In contrast, "q4h" indicates a dosing frequency every 4 hours, leading to a total of six doses in a day. Hence, these abbreviations do not represent the same total number of daily doses.
