A physician orders 7 teaspoons daily of a certain drug in four equally divided doses. Refer to the appropriate entries in the table of English and Metric Equivalents for Capacity to convert given units to the unit indicated. Complete parts a. through d..

Answer 1

a. How many milliliters are in one teaspoon?
There are 5 milliliters in one teaspoon.

b. How many milliliters of the drug will be given in one dose?
In one dose, 7 teaspoons are divided equally, so each dose will be 7/4 = 1.75 teaspoons. Therefore, 1.75 teaspoons x 5 milliliters per teaspoon = 8.75 milliliters of the drug will be given in one dose.

c. How many milliliters of the drug will be given in a day?
Since there are four equally divided doses in a day, the total amount of the drug given in a day would be 4 doses x 8.75 milliliters per dose = 35 milliliters.

d. How many liters of the drug will be given in a week?
Since there are 7 days in a week, the total amount of the drug given in a week would be 7 days x 35 milliliters per day = 245 milliliters. To convert this to liters, we divide by 1000: 245 milliliters / 1000 = 0.245 liters of the drug will be given in a week.
