Subtopic 1: Basic Conversion Skills Between
Celsius and Fahrenheit
Question 1
A patient's temperature reads 100.4°F. What is this temperature in Celsius?
A. 36.0°C
B. 38.0°C
C. 37.0°C
D. 39.0°C
Correct Answer: B. 38.0°C
Rationale: Use the formula: °C = (°F − 32) × 5/9 → (100.4 − 32) × 5/9 =
38.0°C.
Question 2
Convert 39.5°C to Fahrenheit.
A. 101.0°F
B. 102.5°F
C. 103.1°F
D. 104.0°F
Correct Answer: C. 103.1°F
Rationale: Use the formula: °F = (°C × 9/5) + 32 → (39.5 × 9/5) + 32 =
103.1°F.

Question 3
Which Fahrenheit temperature corresponds to a Celsius reading of 35.5°C?
A. 95.0°F
B. 96.5°F
C. 95.9°F
D. 94.0°F
Correct Answer: C. 95.9°F
Rationale: (35.5 × 9/5) + 32 = 95.9°F.
Question 4
A febrile patient presents with a temperature of 38.9°C. What is the
equivalent in Fahrenheit?
A. 101.4°F
B. 102.5°F
C. 100.9°F
D. 102.0°F
Correct Answer: D. 102.0°F
Rationale: (38.9 × 9/5) + 32 = 102.02°F, rounded to 102.0°F.
Question 5
What is the Fahrenheit equivalent of a hypothermic temperature of 32.0°C?
A. 89.6°F
, 4
B. 91.0°F
C. 90.5°F
D. 92.0°F
Correct Answer: A. 89.6°F
Rationale: (32 × 9/5) + 32 = 89.6°F.
Question 6
Convert 41°C, a critical fever temperature, to Fahrenheit.
A. 105.4°F
B. 106.0°F
C. 105.8°F
D. 104.5°F
Correct Answer: C. 105.8°F
Rationale: (41 × 9/5) + 32 = 105.8°F.
Question 7
If a newborn’s temperature is 97.7°F, what is it in Celsius?
A. 35.5°C
B. 36.0°C
C. 36.5°C
D. 37.0°C
Correct Answer: C. 36.5°C
