If the dose of liquid amoxicillin for a child is one and one-half teaspoonful three times a day for 10 days, what is the volume needed to fill the prescription?

100 mL
150 mL
200 mL
225 mL

The correct answer is: 225 mL

To determine the total volume of liquid amoxicillin needed to fill the prescription, first calculate the total daily dose and then the total required over the entire treatment period. The prescription specifies one and one-half teaspoonfuls taken three times a day. One teaspoonful is approximately 5 mL, so one and one-half teaspoonfuls equals 7.5 mL. By taking this three times a day, the total daily dose becomes: 7.5 mL × 3 = 22.5 mL per day. Next, since the treatment lasts for 10 days, the total volume needed is: 22.5 mL/day × 10 days = 225 mL. Thus, this calculation confirms that 225 mL is necessary to fulfill the prescription for the duration specified. This is why the correct answer is 225 mL, as it accurately reflects the total amount of medication the child requires based on the prescribed dosage and treatment duration.
