Section 1: Basic Numeracy and Number Systems (Questions
1–40)
1. A patient's medication dosage is calculated based on the
patient's weight. The dosage requires 5 mg/kg. If the patient
weighs 70 kg, what is the total dosage?
A. 350 mg
B. 350 mg
C. 14 mg
D. 75 mg
Answer: A
Rationale: Multiply the dosage per kg (5 mg) by the patient's weight (70 kg). 5 × 70 =
350 mg. Units of "per kg" indicate multiplication.
2. Which number system includes zero, negative numbers, and
positive numbers?
A. Whole numbers
B. Natural numbers
C. Integers
D. Rational numbers
,Answer: C
Rationale: Integers include all positive and negative whole numbers, including zero.
Natural numbers are positive only, and whole numbers are non-negative. Integers are a
subset of rational numbers.
3. A rational number can be defined as:
A. Any number that can be placed on a number line
B. A number that can be expressed as a ratio of two integers
C. Any non-negative number
D. A number that cannot be expressed as a fraction
Answer: B
Rationale: Rational numbers can be written as a/b where a and b are integers and b ≠
0. This includes terminating and repeating decimals. All integers are rational numbers.
4. Given the set: 3.3, -2.3, -16, 25. What are the square roots of
the whole number?
A. ± 2.3
B. ± 3.3
C. ± 4
D. ± 5
Answer: D
Rationale: The whole number in the set is 25. The square roots of 25 are ±5 because 5
× 5 = 25 and (-5) × (-5) = 25.
,5. What is the greatest common factor (GCF) of 132 and the
square root of 121?
A. 1
B. 2
C. 10
D. 11
Answer: D
Rationale: √121 = 11. The GCF of 132 and 11 is 11 because 11 divides evenly into both
numbers (132 ÷ 11 = 12).
6. Simplify: 3/4 + 2/5 =
A. 5/9
B. 7/9
C. 23/20 = 1 3/20
D. 23/20
Answer: D
Rationale: To add fractions, find a common denominator (20): 3/4 = 15/20, 2/5 = 8/20.
Sum = 15/20 + 8/20 = 23/20, which is an improper fraction.
7. Convert 0.75 to a fraction in simplest form.
A. 75/100 = 3/4
B. 3/4
C. 75/100
D. 7/10
Answer: B
Rationale: 0.75 = 75/100 = 3/4 (divide numerator and denominator by 25).
, 8. Convert 2.5 to a fraction.
A. 5/2 = 2 1/2
B. 25/10 = 5/2
C. 25/10
D. 5/2
Answer: A
Rationale: 2.5 = 25/10 = 5/2 = 2 1/2.
9. Convert 3/8 to a decimal.
A. 0.3
B. 0.35
C. 0.375
D. 0.38
Answer: C
Rationale: 3 ÷ 8 = 0.375.
10. What is 15% of 200?
A. 15
B. 30
C. 40
D. 50
Answer: B
Rationale: 15% = 0.15. 0.15 × 200 = 30.

1. A patient's medication dosage is calculated based on the
patient's weight. The dosage requires 5 mg/kg. If the patient
weighs 70 kg, what is the total dosage?
A. 350 mg
B. 350 mg
C. 14 mg
D. 75 mg
Answer: A

350 mg. Units of "per kg" indicate multiplication.
2. Which number system includes zero, negative numbers, and
positive numbers?
A. Whole numbers
B. Natural numbers
C. Integers
D. Rational numbers
,Answer: C
Rationale: Integers include all positive and negative whole numbers, including zero.
Natural numbers are positive only, and whole numbers are non-negative. Integers are a
subset of rational numbers.
3. A rational number can be defined as:
A. Any number that can be placed on a number line
B. A number that can be expressed as a ratio of two integers
C. Any non-negative number
D. A number that cannot be expressed as a fraction
Answer: B
Rationale: Rational numbers can be written as a/b where a and b are integers and b ≠
0. This includes terminating and repeating decimals. All integers are rational numbers.
4. Given the set: 3.3, -2.3, -16, 25. What are the square roots of
the whole number?
A. ± 2.3
B. ± 3.3
C. ± 4
D. ± 5
Answer: D
Rationale: The whole number in the set is 25. The square roots of 25 are ±5 because 5
× 5 = 25 and (-5) × (-5) = 25.
,5. What is the greatest common factor (GCF) of 132 and the
square root of 121?
A. 1
B. 2
C. 10
D. 11
Answer: D
Rationale: √121 = 11. The GCF of 132 and 11 is 11 because 11 divides evenly into both
numbers (132 ÷ 11 = 12).
6. Simplify: 3/4 + 2/5 =
A. 5/9
B. 7/9
C. 23/20 = 1 3/20
D. 23/20
Answer: D
Rationale: To add fractions, find a common denominator (20): 3/4 = 15/20, 2/5 = 8/20.
Sum = 15/20 + 8/20 = 23/20, which is an improper fraction.
7. Convert 0.75 to a fraction in simplest form.
A. 75/100 = 3/4
B. 3/4
C. 75/100
D. 7/10
Answer: B
Rationale: 0.75 = 75/100 = 3/4 (divide numerator and denominator by 25).
, 8. Convert 2.5 to a fraction.
A. 5/2 = 2 1/2
B. 25/10 = 5/2
C. 25/10
D. 5/2
Answer: A
Rationale: 2.5 = 25/10 = 5/2 = 2 1/2.
9. Convert 3/8 to a decimal.
A. 0.3
B. 0.35
C. 0.375
D. 0.38
Answer: C

10. What is 15% of 200?
A. 15
B. 30
C. 40
D. 50
Answer: B
Rationale: 15% = 0.15. 0.15 × 200 = 30.
