What is the normal oral temperature range?

• A. 96.8-98.0 F
• B. 97.0-99.0 F
• C. 97.6-99.6 F
• D. 98.6-100.6 F

Answer: (C)

Normal oral temperature readings are typically about 97.6 to 99.6 degrees Fahrenheit. This range reflects the usual variation seen in healthy adults and corresponds to a core temperature around 36.4 to 37.6 C. Oral readings can be a bit lower than core temperatures and are influenced by recent intake of food or drink, smoking, and the time of day. For an accurate result, wait after eating or drinking hot or cold items or after smoking, and place the thermometer correctly under the tongue. Ranges that start much lower or extend into fever territory aren’t considered normal for an oral reading, which is why this range is the best choice.
