What is the normal oral temperature in degrees Fahrenheit?

  1. 97.6 degrees F

  2. 98.6 degrees F

  3. 99.6 degrees F

  4. 100.4 degrees F

The correct answer is: 98.6 degrees F

A normal oral temperature for a healthy adult is typically around 98.6 degrees Fahrenheit. This value, established by studies conducted in the 19th century, serves as a baseline for evaluating a person's body temperature. It reflects the average internal body temperature when measured orally and is essential in medical contexts for assessing a patient’s health. The variations in body temperature can occur due to factors such as the time of day, the method of measurement, age, activity level, and individual variability. Normal body temperature may range from about 97°F to 100°F, but 98.6°F is often referenced as the average. This significance is reflected in clinical practice, where a deviation from this average might indicate a potential health issue such as fever or hypothermia. While other options present numbers close to typical variations, 98.6°F is recognized as the standard measure for normal oral temperature, making it the most accurate choice in this context.
