A patient's oral temperature was 99.8°F. What is this temperature in Celsius, rounded to the nearest tenth of a degree?
- A37.5°C
- B37.1°C
- C38.0°C
- D37.7°C
Show answer & explanationAnswer & explanation
Correct answer: D. 37.7°C
To convert Fahrenheit to Celsius, use the formula C = (F - 32) * 5/9. So, C = (99.8 - 32) * 5/9 = 67.8 * 5/9 = 37.666... which rounds to 37.7°C.
Why the other options are wrong
- A. Incorrect calculation.
- B. Incorrect calculation.
- C. Incorrect calculation.
