Final answer:
To determine how much you would dispense for the prescription of Robitussin AC, you need to calculate the total volume based on the dosage instructions. In this case, the correct answer is 200 mL. Therefore, the correct answer is 200 mL (a).
Step-by-step explanation:
To determine how much you would dispense for the prescription of Robitussin AC, you need to understand the abbreviations used in the prescription. 'qid' stands for 'quarter in die,' which means 'four times a day.' '1 tsp' means one teaspoon. Finally, 'for 10 days' tells you that the prescription should be taken for a total of 10 days.
So, if the prescription is to take 1 teaspoon four times a day for 10 days, you would dispense:
1 teaspoon x 4 times a day = 4 teaspoons per day
4 teaspoons per day x 10 days = 40 teaspoons
Since 1 teaspoon is approximately 5 mL, you would dispense:
40 teaspoons x 5 mL = 200 mL
