Feedback
1 This is incorrect. Uncomplicated minor surgery increases the surgical client’s
kilocaloric requirement by only 5%.
2 This is incorrect. Surgery needed to repair soft tissue trauma requires a 14% to
37% increase in kilocalories.
3 This is incorrect. Surgery needed to repair soft tissue trauma requires a 14% to
37% increase in kilocalories, which is not the greatest increase noted.
4 This is correct. Major burns are the most extreme state of stress a client can
sustain and produce a hypermetabolic state that raises kilocaloric needs higher
than those of most other stresses. Kilocaloric requirements may be as high as
8,000 calories per day.
