What is the normal temperature range for tympanic temperature measurement?

The normal temperature range for tympanic temperature measurement is accurately represented by the values given in the first option, which is 96.6-99.7 degrees Fahrenheit. Tympanic temperature measurement, taken in the ear, is a method often used due to its quick and non-invasive nature, and it reflects the core body temperature closely.

This range is consistent with accepted clinical standards for what is considered a typical tympanic temperature. The normal body temperature can vary based on several factors including the time of day and individual metabolic differences, but the specified range covers the average temperatures that can be expected in a healthy individual.

The other ranges provided in the remaining options are either too narrow or extend into levels that do not accurately reflect normal body temperatures. Thus, the first option represents the correct normal range for tympanic readings.
