Final answer:
The normal temperature range is actually 97.7 to 99.5°F (36.5 to 37.5°C), not 96.6 to 99.6°F. Therefore, the statement is false.
Step-by-step explanation:
The statement that the normal range for temperature is 96.6-99.6°F is false. According to the information provided, the normal range for an adult’s body temperature is about 97.7 to 99.5°F (36.5 to 37.5°C). This range is consistent with the body’s efforts to maintain homeostasis for temperature, where fluctuations around the physiological setpoint of approximately 37°C (98.6°F) are normal. It is also mentioned that extreme variances in body temperature might indicate medical conditions such as fever, infection, a tumor, or circulatory problems.
