What is the normal range for an adult's temperature?

The normal range for an adult's temperature orally is generally considered to be between 97.6°F to 99.6°F. This range accounts for variations in individual temperature readings due to factors like the time of day, activity level, and individual physiology.

A temperature reading within this range indicates a healthy body temperature, which is essential for proper physiological functioning. It is often considered that 98.6°F is the average normal body temperature, but normal variations can occur, thus establishing a broader range. This understanding helps nursing assistants to monitor and assess patients accurately, ensuring they can identify when a temperature may indicate a fever or hypothermia, prompting appropriate responses based on deviations outside this normal range.
