MATHEMATICS (50 Questions)
Q1: Multiply 0.06 by 0.021.
A. 0.00126 [CORRECT]
B. 0.0126
C. 0.126
D. 1.26
Correct Answer: A
Rationale: Multiply ignoring decimals: 6 × 21 = 126. Count total decimal places: 0.06 (2
places) + 0.021 (3 places) = 5 decimal places. Place decimal in product: 0.00126.
Option B moves decimal 4 places (common error), C moves 3 places, D ignores
decimals entirely.
Q2: A patient is to receive 500 mg of medication. The tablets available are 250 mg each.
How many tablets should the nurse administer?
A. 0.5 tablets
B. 1 tablet
C. 2 tablets [CORRECT]
D. 4 tablets
Correct Answer: C
,Rationale: Desired dose ÷ Dose on hand = 500 mg ÷ 250 mg = 2 tablets. This is a basic
dosage calculation using the formula method. Ensure units match before calculating.
Q3: Convert 3/8 to a decimal.
A. 0.25
B. 0.375 [CORRECT]
C. 0.4
D. 0.625
Correct Answer: B
Rationale: Divide numerator by denominator: 3 ÷ 8 = 0.375. Common errors: 3 ÷ 8 = 0.4
(rounding too early), or confusing with 5/8 (0.625) or 1/4 (0.25).
Q4: What is 45% of 180?
A. 72
B. 81 [CORRECT]
C. 90
D. 99
Correct Answer: B
Rationale: Convert percentage to decimal: 45% = 0.45. Multiply: 0.45 × 180 = 81.
Alternative: 10% of 180 = 18, so 40% = 72, plus 5% (9) = 81.
Q5: A solution contains 25 grams of dextrose in 500 mL. What is the percentage
concentration?
A. 2.5%
B. 5% [CORRECT]
C. 10%
,D. 25%
Correct Answer: B
Rationale: Percentage (w/v) = (grams of solute ÷ mL of solution) × 100 = (25 ÷ 500) ×
100 = 5%. Common error: using 25 ÷ 100 = 25% (incorrect denominator).
Q6: Convert 1745 military time to standard time.
A. 5:45 AM
B. 5:45 PM [CORRECT]
C. 7:45 PM
D. 5:45 AM
Correct Answer: B
Rationale: Military time 1745: subtract 1200 for PM times = 545 = 5:45 PM. First two
digits (17) represent hour (17 - 12 = 5 PM), last two (45) are minutes. Times 1300-2359
are PM; 0000-1159 are AM.
Q7: Solve for x: 3x + 7 = 22
A. 3
B. 5 [CORRECT]
C. 7
D. 9
Correct Answer: B
Rationale: Isolate x: 3x + 7 = 22 → 3x = 22 - 7 → 3x = 15 → x = 5. Check: 3(5) + 7 = 15 +
7 = 22 ✓
Q8: How many milliliters are in 4.5 liters?
, A. 45 mL
B. 450 mL
C. 4,500 mL [CORRECT]
D. 45,000 mL
Correct Answer: C
Rationale: 1 liter = 1,000 mL. Multiply: 4.5 × 1,000 = 4,500 mL. Metric conversions move
decimal: liters to milliliters = multiply by 10³ (move decimal 3 places right).
Q9: A recipe calls for a ratio of 3:2 flour to sugar. If you use 9 cups of flour, how much
sugar is needed?
A. 4 cups
B. 6 cups [CORRECT]
C. 8 cups
D. 12 cups
Correct Answer: B
Rationale: Set up proportion: 3/2 = 9/x → 3x = 18 → x = 6 cups. The ratio 3:2 means for
every 3 parts flour, 2 parts sugar. Scaling factor: 9 ÷ 3 = 3, so 2 × 3 = 6.
Q10: What is the Roman numeral for 49?
A. XLIX [CORRECT]
B. IL
C. XLVIIII
D. XLXI
Correct Answer: A
