Section 1: Mathematics
1. A nurse needs to administer 2.5 mL of medication. How many doses are in a 250 mL bottle?
A) 10
B) 50
C) 100
D) 500
Rationale: 250 ÷ 2.5 = 100 doses.
2. Convert 0.75 to a fraction in simplest form.
A) 3/5
B) 75/100
C) 3/4
D) 7/10
Rationale: 0.75 = 75/100 = 3/4.
3. Solve for x: 5x − 7 = 3x + 9.
A) 4
B) 8
C) 16
D) 2
Rationale: 5x − 3x = 9 + 7 → 2x = 16 → x = 8.
4. What is 15% of 200?
A) 15
B) 20
C) 30
D) 40
Rationale: 0.15 × 200 = 30.
5. A patient drank 0.5 L of water, 250 mL of juice, and 150 mL of tea. What was the total intake in mL?
A) 650 mL
B) 750 mL
C) 850 mL
,D) 900 mL
Rationale: 0.5 L = 500 mL. 500 + 250 + 150 = 900 mL.
6. Divide 3/4 by 1/2.
A) 3/8
B) 1.5
C) 1/2
D) 6/4
Rationale: 3/4 ÷ 1/2 = 3/4 × 2/1 = 6/4 = 1.5.
7. How many milligrams are in 0.05 grams?
A) 0.5 mg
B) 50 mg
C) 500 mg
D) 5 mg
Rationale: 1 g = 1000 mg, so 0.05 × 1000 = 50 mg.
8. A rectangle has a length of 12 cm and width of 5 cm. What is the perimeter?
A) 17 cm
B) 24 cm
C) 34 cm
D) 60 cm
Rationale: Perimeter = 2(length + width) = 2(12 + 5) = 34 cm.
9. Which number is the largest?
A) 0.045
B) 0.405
C) 0.450
D) 0.504
Rationale: 0.504 is greater than 0.450, 0.405, and 0.045.
10. If a nurse works 7.5 hours per day for 5 days, how many total hours are worked?
A) 35
B) 37.5
C) 40
D) 42.5
Rationale: 7.5 × 5 = 37.5 hours.
11. What is the square root of 144?
A) 10
B) 12
C) 14
D) 16
, Rationale: 12 × 12 = 144.
12. Solve: 8 + 2 × (5 − 3)
A) 10
B) 12
C) 20
D) 14
Rationale: Parentheses first: 5 − 3 = 2. Then 2 × 2 = 4. Finally 8 + 4 = 12.
13. A patient’s temperature rises from 98.6°F to 101.3°F. How many degrees did it increase?
A) 1.7
B) 2.7
C) 3.7
D) 4.7
Rationale: 101.3 − 98.6 = 2.7°F.
14. What is 5/8 as a decimal?
A) 0.58
B) 0.60
C) 0.625
D) 0.875
Rationale: 5 ÷ 8 = 0.625.
15. Convert 2.4 liters to milliliters.
A) 24 mL
B) 240 mL
C) 2400 mL
D) 24,000 mL
Rationale: 1 L = 1000 mL, so 2.4 L = 2400 mL.
16. A medication order is 250 mg. Tablets are 125 mg each. How many tablets are needed?
A) 1
B) 2
C) 3
D) 4
Rationale: 250 ÷ 125 = 2 tablets.
