A prescription is written for azithromycin 200 mg/5 mL with directions to take 1.5 tsp on day one, then 3/4 tsp on days two through five. What is the minimum volume of medication, in mL, that must be dispensed?

Rationale

22.5 mL of azithromycin must be dispensed.

To determine the total volume of medication required, we need to calculate the amount taken on day one and the amount taken over the next four days and then convert these amounts into mL.

A (15) YOUR ANSWER

This choice is incorrect because it underestimates the total volume of medication needed. The day one dose of 1.5 teaspoons (7.5 mL) and the subsequent doses over the next four days (3/4 tsp or 3.75 mL each day) amount to a total far exceeding 15 mL.

B (17.5) YOUR ANSWER

This option is also incorrect as it does not account for the full dosage needed. The total volume from day one and the four subsequent days (7.5 mL + 15 mL) totals 22.5 mL, which is greater than 17.5 mL.

C (22.5) CORRECT

This choice is correct. The calculation involves taking 1.5 tsp (7.5 mL) on day one and 3/4 tsp (3.75 mL) for each of the next four days, leading to a total of 7.5 mL + (3.75 mL x 4 days) = 7.5 mL + 15 mL = 22.5 mL.

D (30) YOUR ANSWER

This choice is incorrect as it overestimates the volume needed. The calculation shows that only 22.5 mL is necessary for the complete course of medication, making 30 mL excessive and unnecessary.

Conclusion

To ensure the patient receives the full prescribed amount of azithromycin, a total of 22.5 mL must be dispensed. This total comprises the initial dose and subsequent doses over the treatment period, highlighting the importance of accurate dosage calculations in medication dispensing.
