Pharmacy Technician Certification Exam Practice Questions Practice Question

A prescription states "Take 2 tsp q.i.d.,dispense 20 doses." What volume,in mL,should be dispensed?

Correct Answer: B

Rationale: To determine the total volume to dispense, first calculate the daily dosage. Taking 2 teaspoons four times a day (q.i.d.) equals 8 teaspoons daily. Since there are approximately 5 mL in 1 teaspoon, 8 teaspoons is equivalent to 40 mL per day. With 20 doses prescribed, the total volume needed is 40 mL multiplied by 20 doses, resulting in 800 mL.

Option A (120 mL) underestimates the total volume. Option C (240 mL) is also too low, as it does not account for the full 20 doses. Option D (800 mL) mistakenly assumes a single daily dose instead of the total for 20 doses. Thus, the correct volume to dispense is 200 mL.
