CHAPTER 1: Math for Clinical Calculations
1. A nurse must convert the fraction 3/4 to a decimal for a dosage calculation.
What is the correct decimal equivalent?
A) 0.34
B) 0.43
C) 0.75
D) 0.80
Answer: C | 3 ÷ 4 = 0.75
2. Express the decimal 0.125 as a fraction in lowest terms.
A) 1/4
B) 1/8
C) 1/6
D) 1/10
Answer: B | 0.125 = 125/1000 = 1/8
3. A medication order requires 2.5 mg. The nurse must round 2.478 mg to the
nearest tenth. What is the correct rounded value?
A) 2.4 mg
B) 2.5 mg
C) 2.48 mg
D) 3.0 mg
Answer: B | The hundredths digit (7) is ≥ 5, so round up.
4. Multiply 0.04 × 0.6. What is the product?
A) 0.24
B) 0.024
C) 2.4
D) 0.0024
Answer: B | 4 × 6 = 24; three decimal places total → 0.024
5. Divide 7.5 by 0.25. What is the quotient?
A) 3
, B) 30
C) 300
D) 0.3
Answer: B | 7.5 ÷ 0.25 = 750 ÷ 25 = 30
6. A dosage calculation yields 1.666… mL. Rounded to the nearest tenth, the
nurse should administer:
A) 1.6 mL
B) 1.7 mL
C) 2.0 mL
D) 1.66 mL
Answer: B | The hundredths digit (6) is ≥ 5, so round up to 1.7.
7. Convert the ratio 1:5 to a fraction.
A) 1/4
B) 5/1
C) 1/5
D) 1/50
Answer: C | A ratio of 1:5 = 1/5
8. A nurse calculates a dose and obtains 0.9875 g. Rounded to the nearest
hundredth, the value is:
A) 0.98 g
B) 0.99 g
C) 1.00 g
D) 0.987 g
Answer: B | The thousandths digit (7) is ≥ 5, so round up.
9. What is the decimal equivalent of the fraction 5/8?
A) 0.58
B) 0.625
C) 0.85
D) 0.525
Answer: B | 5 ÷ 8 = 0.625
10. Add the following decimals: 1.25 + 0.7 + 0.035.
A) 1.985
B) 2.085
