MATHEMATICS (Questions 1-20)
Question 1
A patient consumed 240 mL of water, 150 mL of orange juice, and 90 mL of milk. What is the total
volume consumed in liters?
A. 0.48 L
B. 0.48 L
C. 480 L
D. 4.8 L
Correct Answer: B (0.48 L)

,Rationale: Total mL = 240 + 150 + 90 = 480 mL. To convert mL to liters, divide by 1000: 480 ÷ 1000 =
0.48 L.

Question 2
A nurse must administer 2.5 mg of a medication. The available tablets are 0.5 mg each. How many
tablets should be given?
A. 3 tablets
B. 4 tablets
C. 5 tablets
D. 6 tablets
Correct Answer: C
Rationale: Number of tablets = Total dosage needed ÷ Dosage per tablet = 2.5 mg ÷ 0.5 mg = 5
tablets.

Question 3
What is 15% of 200?
A. 15
B. 20
C. 30
D. 45
Correct Answer: C
Rationale: 15% = 0.15. 0.15 × 200 = 30. Alternatively, 10% of 200 = 20, and 5% of 200 = 10, so 20 + 10
= 30.

Question 4
Solve for x: 3x + 7 = 22
A. x = 3
B. x = 4
C. x = 5
D. x = 6
Correct Answer: C
Rationale: 3x + 7 = 22 → Subtract 7 from both sides: 3x = 15 → Divide both sides by 3: x = 5.

Question 5
A patient's temperature is 37°C. What is this in Fahrenheit?
A. 96.8°F
B. 98.6°F
C. 99.5°F
D. 100.4°F
Correct Answer: B
Rationale: Formula: °F = (°C × 9/5) + 32. (37 × 9/5) + 32 = (37 × 1.8) + 32 = 66.6 + 32 = 98.6°F.

Question 6
What is the least common denominator (LCD) of 1/3, 1/4, and 1/6?
A. 6

, B. 12
C. 18
D. 24
Correct Answer: B
Rationale: Multiples of 3: 3, 6, 9, 12, 15; of 4: 4, 8, 12, 16; of 6: 6, 12, 18. Smallest common multiple is 12.

Question 7
A patient drank 0.75 L of water. How many mL is this?
A. 75 mL
B. 750 mL
C. 750 mL
D. 7500 mL
Correct Answer: B (750 mL)
Rationale: 1 L = 1000 mL, so 0.75 L × 1000 = 750 mL.

Question 8
Simplify: 5/8 + 1/4
A. 3/8
B. 5/12
C. 7/8
D. 6/8
Correct Answer: C
Rationale: Convert 1/4 to 2/8. Then 5/8 + 2/8 = 7/8.

Question 9
What is the square root of 144?
A. 10
B. 12
C. 14
D. 16
Correct Answer: B
Rationale: 12 × 12 = 144, so √144 = 12.

Question 10
A patient weighs 68 kg. Convert this weight to pounds (1 kg = 2.2 lb).
A. 136 lb
B. 149.6 lb
C. 149.6 lb
D. 154 lb
Correct Answer: B (149.6 lb)
Rationale: 68 kg × 2.2 lb/kg = 149.6 lb.
