Section 1: Foundational Math Review - Fractions, Decimals, Percentages (Q1-12)
Q1. A patient is prescribed 1/2 tablet of a medication twice daily. How many tablets
will the patient take in a 7-day period?
A. 3.5 tablets B. 7 tablets [CORRECT] C. 14 tablets D. 3 tablets
Rationale: 1/2 tablet × 2 times daily = 1 tablet per day. 1 tablet × 7 days = 7 tablets.
REVIEW NOTE: Multiply fractions by whole numbers: (1/2) × 2 = 2/2 = 1.
Correct Answer: B
Q2. Convert the improper fraction 17/5 to a mixed number.
A. 2 3/5 B. 3 2/5 [CORRECT] C. 3 3/5 D. 4 1/5
Rationale: 17 ÷ 5 = 3 with remainder 2, so 17/5 = 3 2/5. REVIEW NOTE: Divide
numerator by denominator; quotient = whole number, remainder = new numerator
over original denominator.
Correct Answer: B
Q3. A patient drank 3/4 cup of water at breakfast and 1/2 cup at lunch. What is the
total fluid intake in cups?
A. 1 cup B. 1 1/4 cups [CORRECT] C. 1 1/2 cups D. 2 cups
Rationale: Find common denominator: 3/4 + 2/4 = 5/4 = 1 1/4 cups. REVIEW NOTE:
Convert 1/2 to 2/4, then add numerators: 3 + 2 = 5, keep denominator 4.
Correct Answer: B

Q4. A medication is available as 0.25 mg tablets. The order is for 0.75 mg. How many
tablets should be administered?
A. 1 tablet B. 2 tablets C. 3 tablets [CORRECT] D. 4 tablets
Rationale: 0.75 ÷ 0.25 = 3 tablets. REVIEW NOTE: Decimal division: move decimal in
both numbers equally. 0.75/0.25 = 75/25 = 3.
Correct Answer: C
Q5. Round 2.347 to the nearest hundredth.
A. 2.3 B. 2.34 C. 2.35 [CORRECT] D. 2.4
Rationale: The digit in the thousandths place is 7, which is ≥5, so round the
hundredths digit (4) up to 5. Result: 2.35. REVIEW NOTE: Look at the digit to the right
of your target place value; 5 or above rounds up.
Correct Answer: C
Q6. A hospital's census increased from 120 patients to 150 patients over one month.
What is the percent increase?
A. 20% B. 25% [CORRECT] C. 30% D. 33%
Rationale: Percent change = [(New - Original)/Original] × 100 = [(150 - 120)/120] ×
100 = (30/120) × 100 = 25%. REVIEW NOTE: Always divide by the original value, not
the new value.
Correct Answer: B
Q7. Convert 0.085 to a percentage.
, 3
A. 0.85% B. 8.5% [CORRECT] C. 85% D. 850%
Rationale: Move decimal two places right: 0.085 → 8.5%. REVIEW NOTE: Decimal to
percent = multiply by 100 or move decimal 2 places right.
Correct Answer: B
Q8. A patient is to receive 45% of a 500 mL IV bag. How many mL should be infused?
A. 225 mL [CORRECT] B. 250 mL C. 275 mL D. 300 mL
Rationale: 45% of 500 = 0.45 × 500 = 225 mL. REVIEW NOTE: "Of" means multiply.
Convert percent to decimal first, then multiply.
Correct Answer: A
Q9. What is 3/8 expressed as a decimal rounded to the nearest thousandth?
A. 0.37 B. 0.375 [CORRECT] C. 0.38 D. 0.4
Rationale: 3 ÷ 8 = 0.375 exactly. No rounding needed. REVIEW NOTE: Common
fraction-decimal conversions: 1/8 = 0.125, 3/8 = 0.375, 5/8 = 0.625, 7/8 = 0.875.
Correct Answer: B
Q10. A medication order states to give 2/3 of a 30 mL dose. How many mL should be
administered?
A. 10 mL B. 15 mL C. 20 mL [CORRECT] D. 25 mL
Rationale: 2/3 × 30 = 60/3 = 20 mL. REVIEW NOTE: Multiply fraction by whole
number: (2 × 30)/3 = 60/3 = 20.
Correct Answer: C
