The pharmacy technician receives the following prescription for amoxicillin suspension for a pediatric patient: Give 375 mg amoxicillin suspension b.i.d. X 10 days The pharmacy stocks amoxicillin 250 mg/5 mL suspension. How many mL should the technician calculate for a single dose?

Rationale

7.5 mL of amoxicillin suspension should be calculated for a single dose.

To determine the correct volume of amoxicillin suspension needed for a single dose of 375 mg, we can use the concentration provided (250 mg/5 mL) to perform the necessary calculations.

A (5) YOUR ANSWER

Choosing 5 mL would provide only 250 mg of amoxicillin, which is insufficient for the prescribed dose of 375 mg. Hence, this option does not meet the dosage requirement set forth in the prescription.

B (7.5) CORRECT

This choice correctly calculates the needed volume by recognizing that 250 mg is contained in 5 mL. To find out how many mL corresponds to 375 mg, we set up a proportion: \( \frac{250 \text{ mg}}{5 \text{ mL}} = \frac{375 \text{ mg}}{x \text{ mL}} \). Solving for x gives \( x = \frac{375 \times 5}{250} = 7.5 \text{ mL} \). Thus, this option accurately reflects the required dose.

C (10) YOUR ANSWER

Selecting 10 mL would yield 500 mg of amoxicillin, which exceeds the prescribed dose of 375 mg. This choice represents an overestimation that could lead to potential dosing errors.

D (15) YOUR ANSWER

Choosing 15 mL would provide an even larger amount of amoxicillin, totaling 750 mg, which is significantly higher than the required dose. This option is also an overestimation and not appropriate for the prescription.

Conclusion

Calculating the volume of amoxicillin suspension for a pediatric dose requires attention to the concentration provided. In this case, 7.5 mL is the correct volume needed to deliver the 375 mg prescribed. Understanding how to convert between milligrams and mL using the concentration allows for accurate dosing, which is crucial in pediatric medication management to ensure both efficacy and safety.
