Chapter 1: Arithmetic Needed for Dosage
MULTIPLE CHOICE
1. A patient/client was instructed to drink 25 oz of water within 2 hours but was only able to drink 15 oz.
What portion of the water remained?
a. 2/5
b. 3/5
c. 2/25
d. 25/25
ANS: A
Feedback: Subtract the quantity of water the client drank (15 oz) from the total available quantity (25
oz): 10 oz remain. To determine the portion of the water that remains, create a fraction by dividing 10
oz (remaining portion) by 25 oz (total portion). Therefore, 10 divided by 25 = 10/25. To reduce
fractions, find the largest number that can be divided evenly into the numerator and the denominator
(5). Ten divided by 5 (10/5) = 2; 25/5 = 5. The fraction 10/25 can be reduced to its lowest terms of 2/5.

2. A patient/client was prescribed 240 WWW.TBSM.WS
mL of Ensure by mouth as a supplement but consumed only 100
mL. What portion of the Ensure remained?
a. 5/12
b. 7/12
c. 100/240
d. 240/240
ANS: B
Feedback: Subtract the quantity of Ensure the client consumed (100 mL) from the total available
quantity (240 mL): 140 mL remain. To determine the portion of the Ensure that remains, create a
fraction by dividing 140 mL (remaining portion) by 240 mL (total portion). Therefore, 140 divided by
240 = 7/12. To reduce fractions, find the largest number that can be divided evenly into the numerator
and the denominator (20); 140 divided by 20 (140/20) = 7; 240/20 = 12. The fraction 140/240 can be
reduced to its lowest terms of 7/12.

3. A patient/client consumed oz. of coffee, 2/3 oz. of ice cream, and oz. of beef broth. What is
the total number of ounces consumed that should be documented for the patient/client?
a. 3 3/4
b. 4 5/12
c. 4 2/3
d. 4 4/9
ANS: B
Feedback: Add the amount of ounces consumed. First, change any mixed number to a fraction by
multiplying the whole number by the denominator and then adding that total to the numerator. For the
coffee, 4 2 = 8 + 1 = 9/4; for the beef broth, 2 1
= 2 + 1 = 3/2. Then add: 9/4 + 2/3 (ice cream) + 3/2. When fractions have different denominators, find
the least common denominator (LCD). For 2, 3, and 4, the LCD =
12. Rewrite each fraction using the LCD; divide the LCD by the denominator of each fraction and then
multiply that result by the numerator of the fraction. The new fractions to be added are 27/12 (coffee),
8/12 (ice cream), and 18/12 (beef broth). After conversion of the fractions, the numerators are added
together and the fraction is reduced to the lowest terms.

4. A coffee cup holds 180 mL. The patient/client drank 2? cups of coffee. How many milliliters would

a. 360
b. 420
c. 510
d. 600
ANS: B
Feedback: The coffee cup holds 180 mL. The client drank 2? cups. To estimate the total number of
milliliters consumed, multiply 180 7/3 ( ). When a mixed number is present, change it to an
improper fraction by multiplying the whole number by the denominator and then adding that total to
the numerator: 2 3 = 6 + 1 = 7/3. Therefore, 180 mL × 7/3 = 420 mL (180 ÷ 3 = 60 × 7 = 420).

ANS: C
Feedback: To estimate the amount of kilograms gained, subtract weight on admission (48.52) from
current weight (50.4 kg) = 1.88 kg (weight gained). To subtract decimals, decimals are stacked lined
up. Starting at the far right of the stack, the numbers are subtracted. In the answer, make sure the

Feedback: To add decimals, stack vertically, making sure that all of the decimal points exactly line up.
Starting at the far right of the stack, add each vertical column of numbers. In the answer, make sure the
decimal point lines up exactly with the points above it. To round off a decimal, the final number is
dropped. Add 0.004 g + 0.152 g = 0.156 WWW.TBSM.WS
g (thousandths place) to determine the total number of grams
the client consumed. When the final number (6) is 5 or greater, drop that number and increase the
adjacent number (5) by 1. When you want a number rounded off to the nearest hundredth, look at the
number in the thousandth place and follow the rounding off rule. Therefore, 0.156 = 0.16 g.

Feedback: Percent means "parts per hundred." Percent is a fraction, containing a variable numerator
and a denominator that always equals 100. Therefore, 30% = 30/100 (fraction), 30:100 (ratio), and 0.3
(decimal). To determine the percent of the orange juice the client drank, multiply 30% 16 oz. Using
the decimal format (0.3 16), line up the numbers on the right. Do not align the decimal points.

10. A patient/client is on a 1500 mL fluid restriction for 24 hours. At 3 PM, the client consumed 2/3 of the
fluid allowance for 24 hours. What are the maximum milliliters of fluid remaining that the
patient/client can consume during the evening shift?
a. 400
b. 450
c. 500
d. 550
ANS: C
Feedback: To estimate 2/3 of 1500 mL, multiply 2/3 × 1500. Set up the fraction: 2/3 1500/1 =
3000/3 = 1000 mL (amount of fluid consumed in milliliters). Multiply the fraction by multiplying the
numerators across and then multiplying denominators across. Reduce the answer to its lowest terms.
To determine the amount of fluid left to be consumed, subtract 1000 (amount of fluid consumed) from
1500 mL (total amount of fluid for 24 hours), which equals 500 mL (maximum fluid to be

1. A patient/client was instructed to drink 25 oz of water within 2 hours but was only able to drink 15 oz.
What portion of the water remained?
a. 2/5
b. 3/5
c. 2/25
d. 25/25
ANS: A
Feedback: Subtract the quantity of water the client drank (15 oz) from the total available quantity (25
oz): 10 oz remain. To determine the portion of the water that remains, create a fraction by dividing 10
oz (remaining portion) by 25 oz (total portion). Therefore, 10 divided by 25 = 10/25. To reduce
fractions, find the largest number that can be divided evenly into the numerator and the denominator
(5). Ten divided by 5 (10/5) = 2; 25/5 = 5. The fraction 10/25 can be reduced to its lowest terms of 2/5.

fraction by dividing 140 mL (remaining portion) by 240 mL (total portion). Therefore, 140 divided by
240 = 7/12. To reduce fractions, find the largest number that can be divided evenly into the numerator
and the denominator (20); 140 divided by 20 (140/20) = 7; 240/20 = 12. The fraction 140/240 can be

the total number of ounces consumed that should be documented for the patient/client?
a. 3 3/4
b. 4 5/12
c. 4 2/3
d. 4 4/9
ANS: B
Feedback: Add the amount of ounces consumed. First, change any mixed number to a fraction by
multiplying the whole number by the denominator and then adding that total to the numerator. For the
coffee, 4 2 = 8 + 1 = 9/4; for the beef broth, 2 1

d. 550
ANS: C
Feedback: To estimate 2/3 of 1500 mL, multiply 2/3 × 1500. Set up the fraction: 2/3 1500/1 =
3000/3 = 1000 mL (amount of fluid consumed in milliliters). Multiply the fraction by multiplying the
numerators across and then multiplying denominators across. Reduce the answer to its lowest terms.
To determine the amount of fluid left to be consumed, subtract 1000 (amount of fluid consumed) from
1500 mL (total amount of fluid for 24 hours), which equals 500 mL (maximum fluid to be
administered during evening shift).

11. A patient/client drank 0.375 mL of a medication that was available as 0.75 mL. List the amount of
medication consumed as a fraction of the whole.
a. 1/5
b. 1/4
c. 1/3
d. 1/2
ANS: D
Feedback: The patient/client consumed 0.375 mL of 0.75 mL of a medication. To estimate the amount
consumed, as a fraction of the whole, set up the problem as division: 0.375/0.750. Clear the decimal
points in both the numerator and the denominator by moving each decimal point three places to the
right. Therefore, 375/750 = 0.5 (or 1/2).

12. A laboratory report listed the following four results: bilirubin (0.2), creatinine (1.46), creatinine (0.09),
and albumin (0.75). Identify the smallest amount.
a. 0.2
b. 1.46
c. 0.09
d. 0.75
ANS: C
Feedback: The correct order from smallest to largest is 0.09, 0.2, 0.75, and 1.46. Size is determined by
the number of places that come after the decimal point. One place is “tenths,” two places is
“hundredths,” and three places is “thousandths.” Therefore, 0.09, read as nine hundredths, is smaller
than two tenths, seventy-five hundredths, and one and forty-six hundredths.

13. The laboratory report included these four numbers: 0.355, 0.3, 0.03, and 0.035. Which decimal is the
largest?
a. 0.3
b. 0.03 WWW.TBSM.WS
c. 0.035
d. 0.355
ANS: A
Feedback: The correct sequence from smallest to largest is 0.355, 0.035, 0.03, and 0.3. Size is
determined by the number of places that come after the decimal point. One place is “tenths,” two
places is “hundredths,” and three places is “thousandths.” Therefore, three tenths is larger than three
hundredths, thirty-five thousandths, and three hundred and fifty-five thousandths.
