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 240WmWLWo.f ETnBsuSreMb.yWmSouth 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.
