For the prescription Amoxicillin 250 mg/5 mL 150 mL, what is the total daily drug intake based on the dosage of 2 teaspoons t.i.d.?

A. 15 mL
B. 30 mL
C. 45 mL
D. 50 mL

The correct answer is: B. 30 mL

To determine the total daily drug intake for the prescription of Amoxicillin, it is important to first convert the dosage from teaspoons to milliliters and then calculate the total daily amount based on the frequency of administration. The prescribed dosage is 2 teaspoons three times a day (t.i.d.). Since 1 teaspoon is equivalent to approximately 5 milliliters, administering 2 teaspoons equates to 10 milliliters per dose. Next, to find the total intake for a day, multiply the amount per dose (10 mL) by the number of doses (3). 10 mL per dose × 3 doses per day = 30 mL per day. Therefore, the total daily drug intake of 30 mL reflects the correct calculation based on the prescribed frequency and dosage for the Amoxicillin syrup.
