Answer :
Final answer:
The normal oral temperature range is 97.6°F to 99.6°F, which can vary based on several factors including time of day, activity, and individual differences.The correct answer is:C. 97.6-99.6°F.
Explanation:
The measurement of body temperature is a key indicator of health and physiological status. A standard clinical thermometer is often used to measure oral temperature, which is a reliable method for detecting fever or monitoring body temperature for other clinical reasons. The average body temperature traditionally quoted is 98.6°F, but this mark is at the higher end of the normal body temperature range.
Several studies have shown that normal body temperatures can fluctuate and, in fact, the average may be lower than the long-held benchmark. Normal body temperature is not a single value, but rather a range that can fluctuate throughout the day; it tends to be lower in the morning and higher in the late afternoon and evening. Moreover, individual variations, age, gender, and the method used for measurement (oral, axillary, rectal, tympanic) can also cause variations in normal temperature readings.
