A 32-year-old woman underwent emergency appendectomy 8 hours ago. The nurse checks her vital signs now. Her temperature is 100.4 F.

Which of these is the most likely reason of this relatively high temperature?

A- Over-hydration

B- Post-operative physiological response to surgical trauma

C- Urinary tract infection

D- Wound infection


This is a case of post operative physiological response to surgical trauma. Over-hydration doesn’t cause fever, dehydration does. Urinary tract infection and wound infection are not seen on the first post-operative day.

The correct answer is B
