1.
A medication order requires 0.75 g of a medication. The medication is available as 250 mg
tablets. How many tablets should be administered?
A. 2 tablets
B. 2.5 tablets
C. 3 tablets
D. 3.5 tablets
Correct Answer: C. 3 tablets
Rationale:
First convert grams to milligrams:

Then:
750 mg ÷ 250 mg/tablet = 3 tablets.
2.
A patient's weight decreases from 84 kg to 72 kg. What is the percentage decrease in weight?
A. 12.5%
B. 14.3%
C. 16.7%
D. 18.2%
Correct Answer: C. 16.7%
Rationale:
Decrease = 84 − 72 = 12 kg.
Percentage decrease:
,12 ÷ 84 × 100 ≈ 14.3%
Therefore, the correct answer is actually B. 14.3%.
Test-taking warning: Always divide the change by the original value, not the final value.
3.
A researcher mixes 30 mL of a 20% solution with 70 mL of a 5% solution. What is the
approximate concentration of the resulting solution?
A. 7.5%
B. 9.5%
C. 10.5%
D. 12.5%
Correct Answer: B. 9.5%
Rationale:
30 × 0.20 = 6 mL solute
70 × 0.05 = 3.5 mL solute
Total solute = 9.5 mL
Total solution = 100 mL
9.5 ÷ 100 × 100 = 9.5%.
4. A rectangular laboratory has an area of 96 square feet. If its length is 12 feet, what is its
perimeter?
A. 32 ft
B. 36 ft
C. 40 ft
D. 44 ft
Correct Answer: C. 40 ft
, Rationale:
Area = length × width
96 = 12 × width
Width = 8 ft
Perimeter = 2(12 + 8) = 40 ft.
5. A car travels 180 miles in 3 hours. At the same rate, how far will it travel in 4.5 hours?
A. 240 miles
B. 260 miles
C. 270 miles
D. 300 miles
Correct Answer: C. 270 miles
Rationale:
Rate = 180 ÷ 3 = 60 mph.
Distance = 60 × 4.5 = 270 miles.
6.
A student answers 42 of 50 questions correctly. What percentage did the student answer
correctly?
A. 78%
B. 80%
C. 84%
D. 86%
