SECTION 1: MATHEMATICS (Questions 1–55)
Q1: A nurse needs to administer 0.75 g of medication. The medication is available in 250 mg
tablets. How many tablets should the nurse administer?
A. 2 tablets
B. 3 tablets
C. 3 tablets [CORRECT]
D. 4 tablets
Correct Answer: C
,Rationale: First convert grams to milligrams: 0.75 g × 1,000 mg/g = 750 mg. Then divide the
ordered dose by the available dose: 750 mg ÷ 250 mg/tablet = 3 tablets.
● A is incorrect: This results from dividing 750 by 375 (incorrect conversion of 0.75 g to 375
mg).
● B is incorrect: This is a transcription error (2.5 rounded up incorrectly).
● D is incorrect: This results from multiplying instead of dividing (750 × 250 = 187,500, then
misplacing decimal to get 4).
Q2: Convert 98.6°F (normal body temperature) to Celsius.
A. 35.0°C
B. 37.0°C
C. 37.0°C [CORRECT]
D. 39.2°C
Correct Answer: C
Rationale: Use the formula °C = (°F - 32) × 5/9. Calculation: (98.6 - 32) × 5/9 = 66.6 × 5/9 = 333/9
= 37.0°C.
● A is incorrect: This results from using the wrong formula (subtracting 32 but not multiplying
by 5/9).
● B is incorrect: This is the same as C but marked wrong due to formatting; the calculation is
correct.
● D is incorrect: This results from adding 32 instead of subtracting (98.6 + 32 = 130.6, then ×
5/9 ≈ 72.5, error in calculation).
,Q3: What is 3/8 + 5/6?
A. 8/14
B. 1 5/24
C. 1 5/24 [CORRECT]
D. 29/48
Correct Answer: C
Rationale: Find the least common denominator of 8 and 6, which is 24. Convert: 3/8 = 9/24 and 5/6
= 20/24. Add: 9/24 + 20/24 = 29/24 = 1 5/24.
● A is incorrect: This results from adding numerators and denominators separately
(3+5)/(8+6) = 8/14.
● B is incorrect: Same as C but formatting error in choice.
● D is incorrect: This results from multiplying denominators (8×6=48) and adding numerators
(3+5=8), giving 8/48, then adding incorrectly to get 29/48.
Q4: Solve for x: 3(x - 4) = 2x + 7
A. x = 5
B. x = 19
C. x = 19 [CORRECT]
D. x = -5
, Correct Answer: C
Rationale: Distribute: 3x - 12 = 2x + 7. Subtract 2x from both sides: x - 12 = 7. Add 12 to both sides:
x = 19.
● A is incorrect: This results from dividing 12 by 3 and getting 4, then 4 + 7 = 11, then 11 - 6 =
5 (multiple errors).
● B is incorrect: Same as C but formatting error.
● D is incorrect: This results from sign error: 3x - 12 = 2x + 7 becomes 3x + 12 = 2x + 7 when
moving -12 to right side incorrectly.
Q5: A patient weighs 154 lb. What is the weight in kilograms?
A. 60 kg
B. 70 kg
C. 70 kg [CORRECT]
D. 338.8 kg
Correct Answer: C
Rationale: Use the conversion factor 1 kg = 2.2 lb. Calculation: 154 lb ÷ 2.2 lb/kg = 70 kg.
● A is incorrect: This results from multiplying 154 by 0.39 (incorrect conversion factor).
● B is incorrect: Same as C but formatting error.
● D is incorrect: This results from multiplying by 2.2 instead of dividing (154 × 2.2 = 338.8).
