Correct Answer is C
Explanation
A. 99.6°F: This temperature is higher than expected for an axillary reading. Axillary temperatures are generally lower than oral temperatures.
B. 98.6°F: This reading matches the oral temperature. However, axillary temperatures are usually lower by approximately 1°F compared to oral temperatures.
C. 97.6°F: This is the correct answer because axillary temperatures tend to be about 1°F lower than oral temperatures.
D. 96.6°F: This reading is lower than typically expected for an axillary temperature and would indicate hypothermia, which is not expected if the oral temperature was normal.
