What is the total volume required for the prescription of 1 teaspoon QID for 10 days, given that 1 teaspoon is approximately 5 ml?

1. 150 ml

2. 200 ml

3. 250 ml

4. 300 ml

The correct answer is: 200 ml

To calculate the total volume required for the prescription, first, determine how many doses are taken in a day. Since the prescription indicates a dosage of 1 teaspoon four times a day (QID), that means the patient would take: 1 teaspoon (5 ml) × 4 doses per day = 20 ml per day. Next, since the prescription is for 10 days, multiply the daily volume by the number of days: 20 ml/day × 10 days = 200 ml. Therefore, the total volume required for this prescription is 200 ml, which aligns with the provided answer.
