Question 50

B indicates the highest number of daily doses.

The abbreviation "q4h" signifies that a medication should be taken every 4 hours, which results in 6 doses per day, indicating the highest frequency among the options provided.

A) b.i.d.

The abbreviation "b.i.d." stands for "bis in die," which means twice a day. This results in a total of 2 doses per day, which is significantly lower than the frequency indicated by "q4h."

B) q4h

"q4h" stands for "quater in die," meaning every 4 hours. This translates to 6 doses within a 24-hour period, making it the option that indicates the highest number of daily doses.

C) q.i.d.

The abbreviation "q.i.d." means "quater in die," which corresponds to four times a day. This results in 4 doses per day, which is less frequent than "q4h."

D) q8h

"q8h" indicates that a medication should be taken every 8 hours. This results in a total of 3 doses per day, which is lower than both "q4h" and "q.i.d."

Conclusion

The option "q4h" is definitively the highest in terms of daily doses, allowing for six administrations in one day. All other options—b.i.d., q.i.d., and q8h—offer fewer doses, confirming that "q4h" is the correct choice due to its higher frequency of administration.
