A patient's temperature increased from 98.6°F to 102.2°F. What is the percentage increase in the patient's temperature (rounded to one decimal place)?
- A4.1%
- B3.5%
- C3.7%
- D3.9%
Show answer & explanationAnswer & explanation
Correct answer: C. 3.7%
To calculate the percentage increase, first find the absolute increase (102.2 - 98.6 = 3.6°F). Then, divide the absolute increase by the original temperature (3.6 / 98.6 ≈ 0.03651). Multiply by 100 to get the percentage and round to one decimal place: 3.7%.
Why the other options are wrong
- A. Incorrect calculation; significantly higher than the actual increase.
- B. Incorrect calculation; perhaps a rounding error or miscalculation of the increase.
- D. Incorrect calculation; likely an error in the division or initial subtraction.
