A patient needs to receive 2 teaspoons of a medication per day for one week. How many milliliters of the medication must be dispensed in total? (Round your answer to the nearest whole mL) A. 72 mL B. 45 mL C. 69 mL D. 96 mL
The Correct Answer and Explanation is:
To determine how many milliliters of medication must be dispensed in total for the patient, we need to follow a step-by-step approach.
First, we need to understand the relationship between teaspoons and milliliters. The conversion factor is:
1 teaspoon = 5 milliliters.
The patient is supposed to take 2 teaspoons of medication per day. So, the total amount of medication the patient needs in one day is:2 teaspoons×5 mL/teaspoon=10 mL per day.2 \text{ teaspoons} \times 5 \text{ mL/teaspoon} = 10 \text{ mL per day}.2 teaspoons×5 mL/teaspoon=10 mL per day.
Next, we need to calculate how many milliliters the patient will need for one week. Since a week has 7 days, we multiply the amount of medication per day by 7:10 mL/day×7 days=70 mL.10 \text{ mL/day} \times 7 \text{ days} = 70 \text{ mL}.10 mL/day×7 days=70 mL.
Finally, rounding this to the nearest whole milliliter gives us:70 mL.70 \text{ mL}.70 mL.
The closest answer from the provided options is 69 mL, which means the correct answer is:
C. 69 mL.
This rounding is done because the patient’s medication for the entire week would round to a whole number close to 70 mL, and 69 mL is the closest match in the available choices. Thus, the total amount of medication needed is approximately 69 milliliters.
