Hypehermia 
Select and explain. 
A. Temperature > 41.5, B. > 40 with autonomic dysfunctuion, C. >37.5-38.3 degC, D. 36.5-37.5 degC
C: >37.5-38.3 degC
Answer: C: >37.5-38.3 degC 
Explanation: Hypehermia is elevated body temperature due to failed thermoregulation that occurs when a body produces or absorbs more heat than it dissipates. Extreme temperature elevation then becomes a medical emergency requiring immediate treatment to prevent disability or death.Hypothermia<35.0 degC (95.0 degF)Normal36.5-37.5 degC (97.7-99.5 degF)Fever>37.5-38.3 degC (99.5-100.9 degF)Hypehermia>37.5-38.3 degC (99.5-100.9 degF)Hyperpyrexia>40.0-41.5 degC (104-106.7 degF)Ref: Ganong&;s review of medical physiology-24th edition; page no-317
