Question 1
What is the Fahrenheit equivalent for a patient's room that needs to be kept at 25
degrees Celsius?
A) 70°F
B) 75°F
C) 77°F
D) 80°F
Correct Answer: C) 77°F
*Explanation: The formula to convert Celsius to Fahrenheit is (°C × 9/5) + 32 = °F. So, (25
× 9/5) + 32 = (45) + 32 = 77°F. This conversion is essential in healthcare settings where
different thermometers or facility standards may use different scales .*
Question 2
What is the Celsius equivalent for a patient who is running a fever of 102 degrees
Fahrenheit?
,A) 37.9°C
B) 38.9°C
C) 39.9°C
D) 40.9°C
Correct Answer: B) 38.9°C
*Explanation: The formula to convert Fahrenheit to Celsius is (°F − 32) × 5/9 = °C. So,
(102 − 32) = 70, then 70 × 5/9 = 350/9 = 38.89°C, which rounds to 38.9°C. A fever of
102°F represents a significant elevation from normal body temperature .*
Question 3
Given the following set of numbers: 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
Correct Answer: D) ±5
Explanation: First, identify the whole number(s) in the set. The whole number here is 25.
The square root of 25 is 5, and since both positive and negative values squared equal 25,
the answer is ±5. This concept is fundamental when working with variance and standard
deviation in statistics .
Question 4
Given the following set of numbers: 10, 2.5, -4, -4.5, 5. What is the sum when
adding together only the whole numbers?
A) 5.5
B) 11
,C) 12.5
D) 15
Correct Answer: D) 15
*Explanation: Identify the whole numbers (integers) in the set: 10, -4, and 5. Sum = 10 +
(-4) + 5 = 11. Wait—10 + (-4) = 6, plus 5 = 11. However, the verified answer indicates
15, which suggests that -4 may be excluded, and the whole numbers considered are 10
and 5, summing to 15. Always carefully review which numbers qualify as "whole
numbers" in your specific assessment context .*
Question 5
Given the following expression: 4 + 7 × (6 − 3)². What is the answer using proper
order of operations?
A) 25
B) 46
C) 67
D) 99
Correct Answer: C) 67
*Explanation: Following PEMDAS (Parentheses, Exponents, Multiplication/Division,
Addition/Subtraction): First, parentheses: (6 − 3) = 3. Then exponent: 3² = 9. Then
multiplication: 7 × 9 = 63. Finally addition: 4 + 63 = 67. Remembering order of
operations is critical for accurate dosage calculations and statistical formula
application .*
Question 6
Given the following expression: 5 × (30 − 27)² + 4. What is the correct answer
using proper order of operations?
A) 34
B) 49
, C) 65
D) 81
Correct Answer: B) 49
*Explanation: Parentheses first: (30 − 27) = 3. Then exponent: 3² = 9. Then multiplication:
5 × 9 = 45. Finally addition: 45 + 4 = 49. This reinforces the consistent application of
order of operations across different expressions .*
Question 7
What is the greatest common factor of 132 and the square root of 121 using prime
factorization?
A) 1
B) 2
C) 10
D) 11
Correct Answer: D) 11
*Explanation: The square root of 121 is 11. Prime factorization of 132 is 2 × 2 × 3 × 11 =
2² × 3 × 11. Prime factorization of 11 is simply 11. The greatest common factor is the
product of common prime factors: 11. Understanding GCF is useful when simplifying
fractions in medication calculations .*
Question 8
What is the greatest common factor of 24 and 84 using prime factorization?
A) 2
B) 4
C) 8
D) 12
Correct Answer: D) 12
