What is the normal oral temperature range?

• A. 96.6-98.6 degrees Fahrenheit
• B. 93.6-97.9 degrees Fahrenheit
• C. 97.6-99.6 degrees Fahrenheit
• D. 98.6-100.6 degrees Fahrenheit

Answer: (D)

Normal oral temperature is measured to distinguish what’s typical from what signals fever. In many CNA resources, a practical normal range is about 98.6°F up to 100.6°F. The value 98.6°F is the classic average, and 100.6°F marks the upper limit before fever is considered. Temperatures above this point are typically labeled fever, while lower readings can reflect individual variation or environmental factors. The other ranges either fall too low or extend beyond what’s commonly viewed as the normal window, making them less accurate as a single “normal” range. Remember that body temperature can vary with time of day, activity, and how the measurement is taken, so a small variation around this range is normal.
